A reference check and a background check get lumped together in a lot of hiring workflows, but they answer two different questions. A reference check tells you what people who worked with a candidate think of them. A background check tells you what the public record and verified sources say happened. One is opinion. The other is documentation. Employers who treat them as interchangeable, or who run only one and assume it covers the other, end up with gaps they don’t find out about until something goes wrong.
What a reference check actually catches
A reference check is a conversation. You, or someone on your behalf, calls people the candidate has worked with, usually former supervisors, sometimes peers, and asks about performance, reliability, communication style, and how they handled specific situations. Done well, it can surface things no record will ever show: whether someone showed up consistently, how they responded to feedback, whether they were the kind of colleague people wanted to work with again.
The limitation is baked into the process. The candidate chooses who you call. Nobody hands over the name of a manager who fired them for cause. Many employers, worried about defamation exposure, will only confirm dates of employment and job title, which flattens the reference check into a formality that adds little beyond what the resume already claims. A reference check is a useful, human data point. It is not a verification.
What a background check actually catches
A background check pulls from records: county and state criminal courts, national and state sex offender registries, motor vehicle records, education and employment verification, professional license checks, and in some sectors, exclusion databases and financial history. It doesn’t care whether the candidate likes you or the reference likes the candidate. It reports what’s documented.
That objectivity is also its limit. A clean background check confirms the absence of certain records. It says nothing about whether someone is a good communicator, handles pressure well, or will actually show up reliably. Two candidates can have identical criminal history results and be wildly different hires.
Reference check vs background check, side by side
| Question | Reference check | Background check |
|---|---|---|
| Source of information | People the candidate names | Courts, registries, agencies, verified employers/schools |
| What it measures | Opinion, work style, reputation | Documented facts and records |
| Selection bias | High, candidate picks who’s called | Low, sources are fixed and independent of the candidate |
| Catches criminal history | Rarely, and only if disclosed voluntarily | Yes, within the scope searched |
| Catches work style, reliability, fit | Yes, if the reference is candid | No |
| Typically governed by FCRA | Only if a third party compiles it for you | Yes, when run through a consumer reporting agency |
When FCRA applies to reference checks
This is the part employers most often get wrong. If your own HR staff picks up the phone and calls a candidate’s former manager, that conversation generally isn’t a “consumer report” under the Fair Credit Reporting Act, because you aren’t acting as a consumer reporting agency and no third party assembled the information for a fee. The moment you outsource reference calls to a background check vendor, a staffing partner, or any outside company that compiles the results into a report for you, the analysis changes.
Under FCRA, a report based on personal interviews with people who know the candidate, covering character, general reputation, or mode of living, is an investigative consumer report, a specific category with its own disclosure rules. Before you can request one, the law requires that you mail or deliver a clear written disclosure to the applicant, within three business days of requesting the report, stating that an investigative consumer report may be made and describing its nature and scope. You also have to tell the applicant they can request more detail about that scope, and you have to certify to the reporting agency that you’ve made these disclosures, as set out in 15 U.S.C. § 1681d. Skip that step because “it’s just a reference check” and you’ve created the same compliance exposure as skipping disclosure on a criminal background report.
The same baseline FCRA obligations that apply to any employment background check, permissible purpose, authorization, and adverse action notice if the report factors into a negative decision, apply here too whenever a third party is involved. The FTC’s guidance for employers walks through these obligations directly, and it doesn’t carve out reference-based reports as an exception. If you’re running third-party reference verification alongside a standard background check, both need to be covered by your disclosure and authorization paperwork, not just the criminal history piece. For a deeper walkthrough of what counts as a lawful reason to pull a report in the first place, see our guide on FCRA permissible purpose for background checks.
Why running only one leaves blind spots
Reference checks alone let selection bias do the filtering for you. A candidate with a pattern of conflict at past jobs will simply not list the people who saw it. You end up with a report that confirms what the resume already implied, favorable, self-selected, and thin on anything that would give you pause.
Background checks alone catch documented history but tell you nothing about fit, communication, or how someone actually performs day to day. A candidate can clear every records search and still be a poor hire because they don’t collaborate well, don’t meet deadlines, or misrepresented what their previous role actually involved, something a candid former supervisor would have flagged in thirty seconds. This is also where the two checks catch different kinds of misrepresentation: a background check verifies that the employment dates and degree are real, while a reference conversation can tell you whether the job duties the candidate described bear any resemblance to what they actually did.
Skipping either one also has downstream risk. Employers who hire without adequate screening and then face an incident involving that employee can face negligent hiring claims, where the question becomes whether a reasonable employer would have uncovered the risk with ordinary diligence. Relying on a single, incomplete check is a weaker position than showing you ran both. We cover this exposure in more detail in our piece on negligent hiring risk and employer screening.
A practical sequencing for hiring
Most employers get better results, and cleaner compliance, by sequencing these deliberately rather than running them simultaneously or interchangeably.
Reference checks fit naturally earlier in the process, once you’re down to a short list of finalists but before an offer is extended. They’re part of your decision-making about who to hire, not a final gate, so they belong alongside interviews and skills assessments.
Background checks fit better after a conditional offer has been made. This is standard practice for criminal history specifically, and it’s the sequencing that EEOC guidance on background checks assumes when it discusses individualized assessment of criminal records: you’ve already decided the candidate is qualified based on their skills and interview performance, and the background check confirms there’s nothing in the record that changes that. Running it after the offer, rather than as an early filter, keeps criminal history from being used as a first-pass screen, which is both a fairer process and a more defensible one if a decision is ever challenged. Many states and cities have their own rules about exactly when criminal history can be considered in the hiring timeline, so check your local requirements before finalizing your process.
Putting it together: interview, check references on your finalists, extend a conditional offer, then run the background check as the last step before start date. If either step turns something up, you have an adverse action process to follow, and the earlier stages have already done the work of narrowing the field so that process doesn’t have to happen often.
Frequently asked questions
Can I skip a background check if the references are strong?
No. Strong references reflect the opinions of people the candidate chose to list. They don’t confirm the absence of a criminal record, verify a degree or license, or check a driving history. For any role with safety, financial, or vulnerable-population responsibilities, a background check covers ground a reference conversation structurally cannot.
Do I need written consent for a reference check the same way I do for a background check?
If you or your own staff make the reference calls directly, FCRA generally doesn’t apply and separate consent isn’t required under that law, though your own hiring policy or state law may still call for notifying candidates. If a third party compiles the reference calls into a report for you, it’s typically treated as an investigative consumer report under FCRA, which does require specific written disclosure and authorization before you request it.
What’s the difference between an investigative consumer report and a standard background check report?
A standard consumer report for employment usually draws from records, criminal history, verifications, driving records. An investigative consumer report is built from personal interviews about a person’s character, reputation, or mode of living, which is exactly what a third-party reference check produces. FCRA treats the two differently, and the investigative version carries an added disclosure requirement about the nature and scope of the investigation.
Should reference checks happen before or after the background check?
Reference checks work best earlier, while you’re still comparing finalists, since they’re part of the hiring decision itself. Background checks work best after a conditional offer, once you’ve already decided the candidate is qualified and you’re confirming there’s nothing in the record that changes that.
Can a bad reference alone justify rescinding a job offer?
It can, but the analysis is different from an adverse action based on a background check report obtained through a consumer reporting agency, which triggers specific pre-adverse and adverse action notice steps under FCRA. If the reference information came through a third-party investigative consumer report, treat it the same way you’d treat a background check finding, with notice and a chance to respond, before finalizing the decision.
