Look Up a Phone Number’s Area Code

Enter a +1 number to see its numbering assignment, format, and possible time zone. The lookup runs in your browser.

Enter a phone number

Enter a 10-digit +1 North American number. We check its structure and area-code record, not the caller’s identity or whether the line is active.

What can this lookup tell you?

It can show whether a number follows the +1 numbering pattern and which public area-code assignment it uses. It cannot show a subscriber name, current carrier, live line status, current location, or spam complaint history. Caller ID can also be spoofed.

If the caller claims to represent a company, contact that company using a number from its official website or paperwork. Read the verification guide.
