What is USPhonebook?

USPhonebook is an online phone directory and reverse phone lookup service that allows users to search for personal and business contact information by name, phone number, or address. With a database of over 500 million phone numbers, USPhonebook aims to be a comprehensive resource for finding the owner of nearly any U.S. phone number.
Some of the key features of USPhonebook include:
- Reverse phone lookups to identify the owner of unknown numbers
- People search by name to find phone numbers and addresses
- Business search to locate company contact details
- Background checks for more in-depth information about individuals
- Unlimited searches with a paid membership
How Does USPhonebook Work?
To look up a phone number on USPhonebook, simply enter the 10-digit number into the search bar on the homepage or Reverse Phone Lookup page. USPhonebook will then scan billions of records in its database and return any available information about the number, which may include:
- Full name of the owner
- Current address
- Alternate phone numbers
- Email addresses
- Social media profiles
- Family members and known associates
- Marital status and estimated income range
You can also do a people search by entering a name and location to find matching profiles with phone numbers, addresses, and background details. The business search works similarly – just enter the company name and USPhonebook will surface the business’s phone number, address, website, and other contact info.

Accuracy of USPhonebook Results
Like many other reverse phone lookup services, USPhonebook compiles its data from public records, online directories, social networks, and other third-party sources. While this allows them to build a massive database, the sheer volume makes it difficult to ensure every record is fully up-to-date.
In our experience testing USPhonebook, the accuracy was hit or miss. Well-established landline numbers and business listings yielded the most reliable results, but mobile numbers and less conventional VoIP numbers proved trickier to identify.
Of course, it’s impossible for any phone directory to have perfect accuracy all the time, but this is something to keep in mind when using USPhonebook or similar services. Always verify important details through additional sources before acting on the information.

USPhonebook Pricing & Membership Options
USPhonebook offers both free and paid search options depending on your needs:
- Free search: Look up any phone number to see the city and state it’s registered in. Gives you a general idea of the number’s location but does not reveal the owner’s name or address.
- Paid membership: Unlocks full access to USPhonebook’s people search and background check features. Pricing starts at $4.99 for a 5-day trial, then $29.99/month for unlimited searches. Cancel anytime.
Compared to other reverse phone lookup services, USPhonebook’s pricing is competitive but on the higher side, especially if you only need to look up a couple numbers. For the best value, we recommend the 5-day trial to test out the service before committing to a monthly plan.
How to Opt Out of USPhonebook
If you find your personal information in USPhonebook and want it removed for privacy reasons, you can submit an opt-out request. Here’s how:
- Go to the USPhonebook opt out page
- Enter your phone number and email address in the provided fields
- Complete the CAPTCHA to verify you are a real person
- Click “Remove My Info” to process your opt-out request
USPhonebook states that it can take up to 48 hours for records to be fully removed from their database after submitting the form. Keep in mind that opting out of USPhonebook will not necessarily remove your information from other public records sources they use to compile their listings.
Alternatives to USPhonebook

- NumLookup – A completely free reverse phone lookup service that shows the caller’s name, location, carrier, and line type for numbers in its database. More limited than paid services but a good place to start.

Consider your specific search needs, budget, and how many lookups you’ll be doing when deciding which service is the best fit.
