What Is a Background Check for a Job?

By the Gray Hair Jobs Editorial Team · Published October 7, 2026 · 2 min read

The short answer

A background check is a review an employer may run before hiring to confirm facts about you. It can include past employment, education, criminal records, driving records, or credit history, depending on the job. Employers usually ask for your written permission first. Many background checks happen after a conditional job offer, near the end of the hiring process.

Key points

Background checks confirm information about a job candidate.
What is checked depends on the job and the employer.
Employers using a screening company generally need your written permission.
Checks often happen after a conditional offer.
You can ask what the check will include.

Why it matters in a job search

Background checks are a normal part of hiring for many jobs, especially in healthcare, education, finance, security, and driving. Knowing what to expect helps you prepare and avoid surprises.

It also helps you spot problems. A real employer runs a background check through its own process, usually late in hiring. A stranger who asks you to pay for a background check before an interview may be running a scam.

What it looks like

Depending on the job, a background check might include:

Employment history. Confirming where and when you worked.
Education. Confirming degrees or certificates you listed.
Criminal records. Common for jobs with vulnerable people, money, or security.
Driving records. For jobs that involve driving.
Credit history. For some jobs that involve handling money.
References. Calls to people you listed.

You will usually receive a form to sign giving permission. It may be on paper or online. You may be asked for your full name, past addresses, and date of birth at this stage. Your Social Security number may also be requested, so make sure the request comes from the real employer first.

What to do next

Make sure the dates, titles, and degrees on your resume are accurate. Mismatches cause delays.
Gather the details you might be asked for, such as past addresses and former employers' names.
Only give sensitive information like your Social Security number through the employer's official hiring process, after you have interviewed and received an offer.
If something in your history may come up, consider being ready to explain it briefly and honestly.
Let your references know they may be contacted, and confirm their phone numbers and email addresses are current.

Frequently asked questions

Can I see the results of my background check?

Often, yes. If an employer uses an outside screening company and plans to reject you because of what the report says, federal rules generally require the employer to tell you and give you a copy of the report first. That gives you a chance to point out mistakes. The Federal Trade Commission publishes information about these rights.

Should I pay for my own background check?

Be very cautious. Legitimate employers usually arrange and pay for background checks themselves. Being asked to pay a fee for a background check, especially before an interview, is a common sign of a job scam. If you are unsure, contact the employer through a phone number or website you find on your own.

How long does a background check take?

It varies with what is being checked and how quickly past employers or schools respond. Some take a few days; others take longer. If you have not heard back in a reasonable time, it is fine to politely ask the employer for an update.
