Who Called Me — Phone Number Format and Area-Code Reference

Check a phone number's format, numbering-plan country, number type, and available area-code details. Parsing runs in the browser; results do not identify a subscriber or the caller's current location. Sitewide analytics scripts also load on this page; see the Privacy Policy.

How to Use

Enter the full phone number including the + symbol and country code. The tool parses its numbering format and displays information available in its local reference data. Area codes can be reassigned or used outside their historical region, so they do not prove a caller's location.

What Information is Provided?

Depending on the number and available metadata, the result can include its numbering-plan country, number type, and selected area-code or region details. The tool does not verify that a number is assigned, active, or owned by a particular person.

Why Include the + and Country Code?

The country code is needed to interpret an international number. For example, +1 212 and +212 begin with different country codes. Include the + symbol and country code for the tool to parse the number in the intended numbering plan.
