About Dial Codes

Dial Codes is a free reference for telephone codes: the international calling code of every country and territory, how to dial each one, and the STD (area) codes of 2640 places in India. It also has a small tool that turns a phone number into a WhatsApp chat link.

Where the data comes from

• Country calling codes, exit codes, trunk prefixes and number lengths: the metadata of Google libphonenumber (version 9.0.43 of its Python port), used under the Apache License 2.0. The country codes themselves are assigned by the International Telecommunication Union (ITU) under its E.164 plan.
• STD codes of India: the India area-code file of libphonenumber (Apache License 2.0), which states that it was generated from the National Numbering Plan 2003 of the Department of Telecommunications, Government of India. We grouped the places by state and worked out each code from that file.
• Time zones: the IANA Time Zone Database, which is in the public domain. The clock on a country page is worked out by your own device.

Number patterns such as +44 7XXX XXXXXX only show the shape of a number. They are not real phone numbers.

How current it is

The data was last checked in November 2026. Telephone numbering changes from time to time: countries add digits, and new area codes open. The India list follows the 2003 plan, so it groups some places under the state they belonged to for telecom purposes then. If a call does not connect, check the code with your phone company.
