The United States has approximately 471 million active phone numbers. Our phone number search works with several types of phone numbers, including landline, mobile, and VoIP numbers.
A mobile phone number is a telephone number associated with a mobile phone or cellular device and linked to a specific individual or company, rather than a physical address. The United States has about 388 million mobile phone numbers, the majority of all phone numbers. Our cell phone number lookup tool will use the area code and exchange code analysis to identify which carrier the phone number was originally assigned to.
Here are the top five US cell phone companies in Q1 2025:
A landline phone number, also known as a fixed-line or wireline number, is connected to a fixed telephone network through a wired connection and associated with a specific physical address. Traditional landline usage has been declining steadily, with approximately 18 million connections remaining in the United States as of June 2024. During the reverse landline lookup process, we use NPA-NXX lookup to identify the geographic location of the phone number.
Voice over Internet Protocol (VoIP) numbers are telephone numbers that are associated with internet-based phone systems. VoIP numbers can be either real telephone numbers or virtual numbers. Virtual numbers are not associated with a specific telephone line and can be used to route calls to different devices, or to different locations. This makes VoIP number lookup process very complicated. As of June 2024, in the U.S. there were 65 million VoIP (internet-based) service phone numbers.

Whether you're dealing with suspicious callers, verifying someone's contact information, or trying to reconnect with colleagues and friends, our phone search service can save you time, money, and potential headaches. There are many reasons why people use reverse number check, but here are the most important:
Check phone number owner to solve question like "who called me?". Reverse caller id lookup will help you find who owns a phone number and decide whether it‘s worth answering or calling back.
Caller ID spoofing is when someone makes a fake phone number show up on your phone screen to hide who is really calling you. Never trust caller ID alone, verify and call back a number you find yourself.
Use our service for a spam phone number search. Identify if the unknown caller is reported to be a spammer, telemarketer, or robocall before you answer. Block unwanted calls to protect your privacy.
When an unknown caller claims to represent a bank, government agency, or service provider, verify their identity first. Protect yourself from scammers, prevent identity theft, and avoid financial fraud schemes.
Results will vary based on data availability, country and type of the phone number searched:
Full name of the person or business associated with the phone number.
Full addresses, including street, city, state, and ZIP code.
Historical records give more information of where the owner lived or operated in the past.
Other individuals or companies connected to the same contact information.
Country and area codes indicate the region where a phone number was originally assigned.
Prefix code may indicate the original phone number type (landline/mobile) and carrier or service provider.
Sometimes our partner service may be able to provide additional premium information such as:
