Country Dialing Codes

An international dialing code (also called a country code or ITU-T E.164 code) is the numeric prefix that identifies a country when placing international calls. For example, +359 is Bulgaria, +1 is the United States and Canada, and +44 is the United Kingdom.

First dial the international direct dialing (IDD) prefix of the country you are calling from (00 in Europe and most countries, 011 in the US/Canada, or + from a mobile), then the destination country code, then the local number without the leading zero. Example: from Bulgaria to the US — 00 1 555 1234567 (or +1 555 1234567).

The +1 country code (the North American Numbering Plan — NANP) is shared by the US, Canada, and most Caribbean nations. They differ by the NANP area code that follows (e.g. 1242 for the Bahamas, 1876 for Jamaica). +7 is shared by Russia and Kazakhstan.

The "+" symbol is a universal placeholder for the IDD prefix when dialing from a mobile phone. "+359 88..." works from any country because the phone replaces "+" with the local IDD prefix automatically (00, 011, etc.).

No. Dependent territories often share the country code of their parent nation. French Guiana uses +594, while Guadeloupe uses +590. This list includes both sovereign nations and major dependent territories with their own ITU code.

Codes follow the ITU-T E.164 recommendation (current 2025) — the official international standard for telephone numbering. No external services are queried — everything runs in your browser.
