Running a background check by phone number has become a standard safety practice for parents and smartphone users alike. Unknown callers flood our phones daily, and about 33% of Americans report receiving scam calls at least once a week.
A background search service can tell you who’s calling before you pick up and whether that caller deserves your attention or should be blocked.
These tools pull data from public records, social media, and telecom databases to give you a clear picture of the person behind the number. Here are seven services that I’ve tested and found reliable.
What Information Can You Get From a Phone Number Background Check
A background phone number check can reveal more than just a name. Most services scan public databases, court records, and online profiles to compile detailed reports.
The amount of information you get depends on the service you choose and whether the number has a digital footprint.
Here’s what you can find with a reverse phone lookup:
- Owner’s full name and any known aliases
- Current and past residential addresses
- Email addresses linked to the phone number
- Social media profiles and online accounts
- Carrier information and phone type (mobile, landline, VoIP)
- Relatives and known associates
- Criminal records and court documents (on premium plans)
This information helps you decide who to let into your life through your phone.

Tips to Determine the Best Phone Number Background Check Service
Not all reverse lookup services work the same way, and the best one for you will depend on what you need. Before you choose a background phone number check, think about these things:
- Look at the size of the database. Services with bigger databases usually give more accurate results. Look for platforms that get their information from many sources and update their records once a month.
- Understand what’s free vs. paid. Most services offer free basic lookups that show a name and location. Detailed reports with criminal records and social media usually require payment.
- Look over the policy for cancellations. A lot of services automatically renew after a trial period. If you only need one search, set a reminder to cancel. Otherwise, choose pay-per-report options.
- Check the area that is covered. Most services only work with US phone numbers. TrueCaller works in more countries than the other apps if you need to look up people in other countries.
- Think about privacy. Find out if the service keeps track of your searches or shares your information with other companies. You and the person you’re looking up are both safe when you do an anonymous search.
