Read a phone number

What this tool does not know

It has no access to carrier records, so it cannot give you a name, a carrier or a line type. It does not know whether a number is a scam either. Spam labels on your phone are estimates by your carrier or an app, and they are wrong in both directions sometimes. If a number is reported as spam, treat that as a hint and not a verdict.

The number you type is processed on our server to produce this page and is not saved to a database. Ordinary web server logs, however, record the requested address, which includes the digits, and those logs rotate after about a week. If that bothers you, type only the area code and three more digits.

What to do with an unfamiliar call

1. Do not call back a number that rang once and hung up. Calls to some Caribbean codes can be billed at international rates.
2. Look for the organization's own website and compare the number with the contact page. Our walkthrough of free ways to identify a caller shows how.
3. If a caller claims to be your bank or the government, hang up and phone the number printed on your card or on the official site.
4. Block the number in your phone, and report scams at reportfraud.ftc.gov. Text messages can be forwarded to 7726.

Curious why paid sites seem to know more? Our explainer covers where that data comes from, and it is not as impressive as the ads suggest.

How to read each field of the result

The region is the state, province or territory the area code was assigned to. It describes where the line was first set up. People move and keep their numbers, and mobile numbers travel with them, so treat the region as background, not as the caller's location. The main places are the larger cities the code covers, listed as a quick sense of geography. The time zone matters more than it seems: a call at what is 3 a.m. there and 6 a.m. for you tells you the caller did not check, which is one more reason to suspect an automated dialer.

The notes underneath flag patterns. A toll-free code such as 800, 888 or 877 means a business or a service that pays for incoming calls, and the number can ring anywhere. A 900 number is premium-rate and may charge you to call it. Some Caribbean and Canadian codes look domestic but belong to other countries, which is why a one-ring call from an unfamiliar code is a poor invitation to ring back.

Common situations

If a number has called once and left no message, do nothing and let it go. If it keeps calling, block it in your phone. If it left a voicemail naming a company, find that company's own website yourself and compare the number. Our guide to free ways to identify a caller walks through the steps, and for business callers see how to find the company behind a number. If you suspect a lookup report is wrong about someone, read how to treat it.

What to do next

1. Do not call back a number you do not recognize, especially after one ring.
2. Never give out codes, account numbers or card details to an inbound caller.
3. Block the number and report scams at reportfraud.ftc.gov. Forward spam texts to 7726.
