Dialing Code to Country

About this calculator

This tool looks up which country or countries correspond to a given international calling code (such as +90 for Turkey or +1, shared by the US, Canada and several Caribbean nations) as assigned under the ITU-T E.164 numbering plan, the international standard that governs how phone numbers are formatted worldwide. Some codes map to a single country while others, like +1 and +7, are shared "world zone" codes split further by area code.

Travelers, call center and telemarketing operators, developers building phone-number validation into forms, and anyone receiving an unfamiliar international call use this to quickly identify the origin of a dialing code. Enter a dialing code to see the matching country or countries.
