No federal law stops you from running a background check the moment you post a job. That surprises people. What federal law controls is what you do with the check once you have it, and that's exactly why most employers wait anyway.
The safer, more common practice is to wait until after you've made a conditional job offer. Not because one law demands it everywhere. Because running a check earlier creates real legal exposure, and because a lot of states and cities do demand it, even if yours doesn't yet.
Search the Fair Credit Reporting Act for a section on "when in the hiring process." You won't find one.
FCRA controls disclosure, written authorization, and the adverse-action notice you owe someone before you turn them down over a report. It doesn't say when in your process you're allowed to pull that report.
So to say that again a different way: FCRA is a rulebook for how you run a check, not a calendar for when you run it. That gap is where a lot of the confusion starts.
There's one real federal timing rule worth knowing, and it's not about criminal background at all. The Americans with Disabilities Act (ADA) requires medical exams and disability-related questions to wait until after a conditional offer. That rule is real, and it's federal. It's just specific to medical inquiries, not criminal history checks.
People sometimes assume that ADA rule covers background checks in general. It doesn't. That's an easy mix-up, and worth getting right.
If there's no federal timing law for criminal background checks, why does almost every HR guide tell you to wait? Two reasons, and they're both bigger than they sound.
First, disparate impact. The Equal Employment Opportunity Commission (EEOC) has said for years that screening everyone out for a criminal record before you've even evaluated them as a candidate can end up screening out certain protected groups more than others. Lawyers call that a disparate impact.
That's a Title VII problem, the federal law against workplace discrimination, not a background-check-law problem. It exists whether or not your state has a ban-the-box law on the books. I've written more on how FCRA and Title VII work as two separate rulebooks here, if you want the fuller version.
Second, a growing number of states and cities have made "after the offer" a legal requirement outright, not a suggestion. We cover that landscape in our ban-the-box guide, and cities like New York City run their own layered rules on top of state law.
If one of those applies to where you're hiring, that law controls, full stop. This article is about the baseline underneath all of it, the practice most employers follow even where nothing forces their hand.
A conditional offer is a real job offer, not a maybe. You tell the candidate the job is theirs, pending something specific, like a background check or reference check coming back clean.
That's different from telling someone "you're a finalist" or "we really like you" without ever using the word offer. Vague language doesn't count as a conditional offer. Treating it like one is exactly the kind of shortcut that gets employers in trouble.
Put it in writing. State the condition plainly: this offer is contingent on a satisfactory background check. Then run the check. That order matters.
Say your state has no ban-the-box law, and your business is small enough that Title VII enforcement feels distant. You could screen every applicant before you even interview them. I'd still tell you not to.
Here's why, from having sat on the vendor side of this for years. You're paying for a report on every applicant instead of just your finalist. That adds up fast once you're hiring at any real volume.
You're also forming an opinion about someone's record before you've talked to them about the job, their experience, or how an old offense actually relates to the work. That's the exact setup the EEOC has flagged as risky. It's also, frankly, a bad way to hire good people.
And there's a documentation problem. Reject someone after a pre-interview screen, and if they also happen to be older, or a member of a protected class, you've made it easier for them to argue the record was a pretext instead of the real reason.
Rejecting after a real interview and a real offer, tied to a specific, job-related finding, is a much harder claim to challenge. That part's not optional in my book, law or no law.
Not every check carries the same risk. Employment verification, education verification, and reference checks aren't about someone's criminal history, so they don't carry the disparate-impact concern driving ban-the-box laws.
Plenty of employers run those earlier, sometimes right after a strong interview, before extending any offer at all. That's common, and generally fine.
One rule still applies no matter what you're checking or when: FCRA requires a disclosure and signed authorization before you pull any consumer report. Criminal background and credit checks are the ones I'd hold until after the offer. Everything else is a lower-stakes, case-by-case call.
If you're setting this up for the first time, here's the sequence I'd use.
Check your specific state and city rules before you finalize this. Some of them add steps, tighten the timing further, or push the trigger point even earlier than what's described here.
