What Do Background Checks Really Look Into? 5 Truths and 3 Strategies

What Do Background Checks Really Look Into? 5 Truths and 3 Strategies

You're changing jobs, and HR tells you "we need to run a background check." Many people tense up at the words "background check" — what will they look into? Will they discover that some parts of my resume aren't entirely accurate? Will someone from my previous company say bad things about me? Actually, background checks aren't as scary as you think, nor are they as arbitrary. Understanding the truth about background checks helps you handle them with confidence. Today, we'll cover the 5 truths about background checks and 3 strategies for dealing with them.

Truth 1: Background Check Scope — They Don't Check Everything, But Core Information Is Always Verified

Many people think background checks mean "turning you inside out" and checking everything. That's not the case. Background checks have a defined scope — they don't check everything, but core information is always verified.

• Must-check items: Identity information (name, ID number, household registration, etc. — confirming you are who you say you are); education and degrees (whether they're real and verifiable on CHSI); work history (which companies you've worked at, tenure, job titles); criminal records (whether you have any criminal convictions); conflicts of interest (whether you hold shares or positions at competitor companies). These are checked by virtually all companies
• Optional-check items: Salary level (actual salary at the previous company, not just what you stated); work performance (your previous company's evaluation of you); reason for departure (voluntary resignation or termination); professional qualifications (whether required certifications for certain roles are genuine); credit history (especially important in the financial industry). Whether these are checked depends on the depth of the background check and the position level
• Non-check items: Content of your personal social media accounts (unless involving trade secret leaks); your family background (unless involving conflicts of interest); your political views and religious beliefs (legally prohibited from discrimination); your health status (legally prohibited from employment discrimination). These are personal privacy, and legitimate background check companies won't investigate them
• Check depth correlates with position level: Regular positions typically only check must-check items, completed in 1-3 days; mid-level management positions check most optional items, completed in 3-5 days; executive positions check nearly everything, completed in 1-2 weeks. The higher the position, the deeper the check
• Real case: Xiao Qin applied for a regular operations role, and the background check only verified identity, education, and work history — completed in 2 days. His friend applied for a VP position at another company, and the check took 2 weeks, including requiring salary bank statements from the previous company

Background checks aren't a "bottomless pit" — they have clear scope and boundaries. Understanding what will and won't be checked eliminates the anxiety of unknown fears.

Truth 2: Background Check Methods — It's Not Secretive; Most Require Your Authorization

Many people think background checks are done secretly without your knowledge. That's not true. In a proper background check process, most checks require your authorization and cooperation.

• Authorization requirement: Legitimate companies must obtain your written authorization before conducting a background check. Without your authorization, the background check company cannot access your personal information. If you refuse authorization, the company can choose not to hire you, but they cannot conduct a check without authorization
• Information provision: During the background check, you need to provide some basic information, such as your ID number, education certificate numbers, and contacts at previous companies. The background check company verifies information based on what you provide
• Verification methods: Identity information is verified through public security systems; education and degrees through CHSI; work history by contacting the previous company's HR or direct supervisor; criminal records through police certificates; salary levels through bank statements or social insurance payment records. Each type of information has different verification channels
• Previous company contact: When the background check company contacts your previous employer, they typically reach out to the references you provided (usually your former direct supervisor or HR). Some background check companies may also find references independently, but legitimate ones will inform you in advance
• Real case: Xiao Han received an email from the background check company before starting, asking him to fill out an authorization form and provide relevant information. He carefully read the authorization scope and found it only covered identity, education, and work history verification — nothing beyond reasonable scope — so he signed the authorization

Legitimate background checks aren't secretive "covert investigations" — they're transparent processes with authorization, procedures, and boundaries. If you encounter a company conducting checks without authorization, that's non-compliant, and you have the right to refuse.

Truth 3: Salary Verification — Your Word Doesn't Count; Your Previous Company's Records Do

Salary is one of the most sensitive aspects of background checks. Many people slightly "enhance" their salary on resumes — writing 15,000 when they actually earned 12,000, or including annual bonuses in the monthly figure. But during background checks, your salary will be verified — it's not whatever you say; your previous company's records determine the truth.

• Verification methods: Background check companies typically ask for your bank statements from the past 6 months, or estimate your actual salary through social insurance contribution bases. Bank statements are the most direct evidence — how much money actually hit your account each month is crystal clear. Social insurance contribution bases also reflect your salary level, though some companies pay at the minimum base
• Common issues: The salary on your resume doesn't match your actual salary. If you wrote 15,000 but actually earned 12,000, the discrepancy will be discovered during the check. Small discrepancies (within 10%) generally won't affect hiring; larger discrepancies (over 20%) may cause the company to question your integrity and even rescind the offer
• Why salary verification matters so much: Salary is an important measure of a person's market value. If you falsify your salary, the company will assume you might falsify other things too. Integrity is the baseline of the workplace — once questioned, it's hard to recover
• How to handle it: Write your actual salary on your resume — don't inflate it. If you feel your salary was low, you can explain the reasons during the interview (e.g., the company's overall salary level was low, or you accepted a pay cut for growth opportunities) rather than falsifying the numbers. Honesty is more persuasive than inflated figures
• Real case: Xiao Xu wrote 18,000 monthly salary on his resume, but bank statements during the background check showed 14,000. The new company's HR asked about the discrepancy. Xiao Xu explained that 18,000 was his annual income including year-end bonus divided by 12. HR understood but asked him to note the salary composition on future resumes. The offer wasn't affected, but the process was nerve-wracking

Salary verification is the "monster-revealing mirror" of background checks — whether you've been honest about your salary becomes immediately clear. The safest strategy is to report honestly and not play games with numbers.

Truth 4: Education Verification — CHSI Reveals Everything; Falsification Will Be Discovered

Education falsification is the easiest way to get caught in a background check. That's because education verification is extremely simple — CHSI (China Higher Education Student Information) reveals everything. No matter what education you've fabricated, if it's not on CHSI, it doesn't exist — there's no room for luck.

• Verification method: Background check companies verify your education and degree information through CHSI. Enter your name and ID number, and all your education information appears — certificate numbers, institutions, majors, graduation dates. If your education can't be found on CHSI, it's falsified
• Common education falsification methods: Fabricating non-existent education (claiming a bachelor's degree when you never attended university); inflating education level (writing bachelor's when you have an associate degree, or master's when you have a bachelor's); fabricating institutions (writing 985/211 when you attended a regular university); changing major names (writing a hot major when you studied an unpopular one). All these methods fail against CHSI
• Consequences of education falsification: Once discovered, the offer will be immediately rescinded. Even if you've already started working, the company can terminate your labor contract for "providing false information" without any economic compensation. More seriously, education falsification can be recorded in your professional credit history, affecting future job searches
• Overseas education verification: Overseas degrees are verified through the Ministry of Education's Chinese Service Center for Scholarly Exchange certification system. If you have an overseas degree, you need to complete degree certification in advance
• Real case: Xiao Tian wrote on his resume that he graduated with a bachelor's degree from a 985 university, but he actually only had an adult education associate degree from that institution. The background check showed an associate degree on CHSI, inconsistent with his resume. The offer was immediately rescinded, and Xiao Tian was also added to a recruitment platform's blacklist

Education falsification is the most basic mistake in background checks — because verification is so simple, CHSI reveals everything. Don't gamble on this issue. Reporting your education honestly is the most fundamental integrity baseline.

Truth 5: Work Performance Verification — Former Colleagues' Evaluations Matter, But Aren't Decisive

Work performance verification is the most "subjective" aspect of background checks. The background check company will contact your former direct supervisor or colleagues to learn about your work performance, professional conduct, and teamwork abilities. But former colleagues' evaluations are subjective, not decisive — the new company will consider them holistically and won't reject you based on one person's negative review.

• Verification content: Background check companies typically ask former colleagues the following questions — How was this person's work attitude? Professional competence? Teamwork ability? Any disciplinary violations? What was the reason for departure? Would you work with them again? These questions cover the main aspects of work performance
• Subjectivity of evaluations: Former colleagues' evaluations inevitably carry subjective coloring. If you had a good relationship, they might give very positive reviews; if you had conflicts, they might give lower ratings. Background check companies and new employers know this, so they won't treat a single evaluation as decisive
• Multi-dimensional verification: Legitimate background check companies don't just contact one reference — they typically reach out to 2-3, including your direct supervisor, peer colleagues, and HR. Cross-validating evaluations from multiple dimensions produces a relatively objective conclusion. If 2-3 references give consistent evaluations, the credibility is high
• Impact of negative reviews: Will a negative review from a former colleague affect hiring? It depends on the content. If the negative review involves integrity issues (e.g., fraud, stealing trade secrets), the impact is significant; if it's just "personality clash" or "different working styles," the impact is minimal. New companies distinguish between "character issues" and "personality differences"
• Real case: During Xiao Yin's background check, his former supervisor gave excellent reviews, but one former colleague said something negative. The background check company contacted two other former colleagues, and both gave positive evaluations. The new company concluded after comprehensive consideration that the negative review was due to personal friction and didn't affect hiring. Xiao Yin successfully joined the company

Work performance verification is the least controllable aspect of background checks, but also the least worth panicking about. Legitimate background checks use multi-dimensional verification and won't reject you based on one person's evaluation. The key is the overall impression you left at your previous company — if most people evaluate you positively, an individual negative review won't be fatal.

Strategy 1: Don't Falsify Your Resume — This Is the Fundamental Approach to Background Checks

The root of all background check problems is resume falsification. If you haven't falsified anything on your resume, the background check is just a formality. So the fundamental strategy for handling background checks is: don't falsify your resume.

• Report salary honestly: Don't inflate your salary. If you feel your salary was low, explain the reasons during the interview rather than falsifying numbers. Discovered salary inflation can not only cost you the offer but also damage your professional credibility
• Report education honestly: Don't fabricate or inflate your education level. CHSI reveals everything — falsification will be discovered. If you have an associate degree, write associate degree; if you have a self-taught bachelor's, write self-taught bachelor's. Education isn't the only measure of ability, but integrity is non-negotiable
• Report work history honestly: Don't fabricate non-existent companies or positions, don't extend tenure dates, and don't exaggerate job responsibilities. Work history is a key verification item in background checks — any inaccuracy may be discovered
• Explain departure reasons honestly: Don't hide termination experiences. If you were terminated, you can explain the reasons and your reflections during the interview rather than fabricating "voluntary resignation." Honestly facing your past is more persuasive than fabricating a perfect story
• The line between "enhancement" and "falsification": Enhancement is highlighting your strengths and achievements (e.g., "led XX project, improving efficiency by 30%"); falsification is fabricating non-existent facts (e.g., claiming you "led XX project" when you only participated in a small portion). Enhancement is acceptable; falsification is absolutely not

Not falsifying your resume is the "get out of jail free card" for background checks. If you haven't falsified anything, the check is just a formality — you have nothing to worry about.

Strategy 2: Notify Former Colleagues in Advance — Let References Be Prepared

Background checks will contact your former colleagues, so notifying potential references in advance so they're prepared is essential.

• Choose appropriate references: Background checks typically require 2-3 references, including your former direct supervisor and peer colleagues. Choose people who have a good relationship with you and understand your work capabilities. Don't choose people you've had serious conflicts with
• Communicate in advance: Before the background check begins, contact your references and let them know you're job hunting and that a background check company may reach out. Briefly mention the position and company you're applying for so they have context. You don't need to "rehearse" — just let them know to expect a call
• Express gratitude: References are spending time taking background check calls for you — express your appreciation. No need for gifts or money (which might actually raise suspicion with the background check company) — a sincere "thank you" is enough
• If you have a poor relationship with your former supervisor: If you're worried about negative evaluations from your former direct supervisor, you can explain the situation when providing references and offer alternative people who can vouch for your work capabilities (e.g., leaders from other departments you collaborated with, or supervisors from your previous-previous company). Legitimate background check companies will understand and accept this
• Real case: Xiao Wu contacted his former supervisor and two former colleagues before the background check, letting them know to expect a call. The former supervisor said he'd provide an honest evaluation, and the two colleagues agreed to cooperate. The background check went smoothly, with all three references giving positive evaluations

Notifying references in advance isn't "rehearsing" — it's basic courtesy and preparation. Letting references know about the upcoming call helps them cooperate better and avoids catching them off guard.

Strategy 3: Know Your Own Background Check Records — Discover Problems Early, Solve Them Early

Before the background check, you can "background check" yourself — verify that your information matches your resume and identify and resolve any issues in advance.

• Check education: Log into CHSI and verify your education and degree information is correct. If you find errors (e.g., school name, major name, graduation date), contact your school to correct them promptly. If your education can't be found on CHSI (e.g., early degrees not in the system), prepare relevant supporting documents in advance
• Check social insurance: Log into your local social insurance platform and review your payment records. Social insurance records reflect your work history and salary level. If you find discrepancies between social insurance records and your resume (e.g., a period of employment without social insurance contributions), prepare an explanation in advance
• Check credit: Log into the People's Bank of China Credit Reference Center and review your personal credit report. If you're applying for a position in the financial industry, credit history is a must-check item. If you find issues in your credit record (e.g., overdue payments), prepare an explanation in advance
• Check business registration: Search your name on Tianyancha or Qichacha to see if you have any registered companies or business registrations. If you hold shares or positions at a competitor company, it may be considered a conflict of interest
• Real case: Xiao Gong checked CHSI before his background check and discovered his graduation date was half a year earlier than what he wrote on his resume (he had misremembered). He corrected the information on his resume in time, avoiding the embarrassment of an "inconsistency" being discovered during the check

Knowing your own background check records in advance is like taking a practice test before the real exam — discover problems, solve problems, and you won't panic during the "real test."

3 Common Background Check Questions: Answers to Your Biggest Worries

The 3 most frequently asked questions about background checks, answered.

• Question 1: Will the background check contact former colleagues I didn't provide? Answer: Legitimate background check companies generally only contact the references you provide. However, some companies (especially for senior positions) may find references independently through industry connections. If the background check company wants to contact references you didn't provide, they should inform you in advance. If you're worried about a particular former colleague giving negative reviews, you can explain the situation when providing your references
• Question 2: Can I omit a very short employment period (less than 3 months) from my resume? Answer: Yes, you can. Your resume is information you voluntarily provide, and you have the right to choose which experiences to showcase. But if you do include it, you must report it accurately. If the background check company discovers this period through social insurance records and asks about it, you can explain "the experience was too short and irrelevant to the position, so I didn't include it on my resume." Most companies will understand
• Question 3: If the background check finds discrepancies, will the offer definitely be rescinded? Answer: Not necessarily. It depends on the nature and extent of the discrepancy. If it's a minor error (e.g., start date off by one month, slightly different job title), most companies won't care. If it's major falsification (e.g., fake education, fabricated work history), the offer will almost certainly be rescinded. The key distinction is between "honest mistakes" and "intentional deception" — the former can be explained, the latter is unforgivable

Background checks aren't a monster — they're just an information verification process. If your resume is honest and your experience is real, the check is a formality. If your resume has inflation, the check is a mirror that reveals the truth.

Conclusion: Background Checks Aren't Scary — Falsification Is

The 5 truths about background checks — they have scope, they require authorization, salary will be verified, education is easily checked, and work performance is multi-dimensionally verified — tell you a core fact: background checks are an information verification process, not a fault-finding tool. The 3 strategies — don't falsify your resume, notify former colleagues in advance, and know your own records — give you a complete path from preparation to response. Background checks aren't scary — falsification is. As long as your resume is truthful and your experience is genuine, the background check is just a formality. Remember: integrity is the hardest passport in the workplace, and background checks only verify whether that passport is genuine.
