What is a country calling code?

Country calling codes are the numeric prefixes that identify a nation or numbering zone in international telephone dialing. They are defined by the ITU-T E.164 standard and appear after your international access prefix (like 00 or 011) and before the national number. Example: to call a number in France from the United States, you dial 011 (US international access) + 33 (France’s country code) + the local number.

Key points at a glance

Standard: ITU-T E.164 defines international numbering, including country codes.
Length: Country codes are 1–3 digits; national numbers that follow vary in length by country.
Access prefix: Many countries use 00; the US/Canada and other NANP regions use 011.
Roaming prefixes: Mobile devices often accept the plus sign (+) as a universal international access indicator.

Regional patterns (first digit of the country code)

While there are exceptions, the first digit often hints at the region:

+1 — North American Numbering Plan (NANP): United States, Canada, and ~20+ territories share +1 but have distinct area codes.
+2 — Africa (most assignments), with some island territories and special cases.
+3 and +4 — Europe.
+5 — Latin America and parts of the Caribbean.
+6 — Oceania and parts of Southeast/South Asia.
+7 — Russia and Kazakhstan (shared zone).
+8 — East and Northeast Asia; also includes some global service ranges (for example, international freephone in +800).
+9 — West, Central, and South Asia, and the Middle East.

Interesting facts about calling codes

Shared code, different places: The NANP uses +1 for multiple countries and territories; area codes distinguish each participant.
Historic splits and new codes: Country reorganizations have created new codes (for example, +420 for the Czech Republic and +421 for Slovakia after the split of Czechoslovakia).
Global service codes: Some ranges are not tied to a single country, such as +800 for international freephone services.
Territories vs. parent states: Some territories share their parent’s code (e.g., +44 for the UK and crown dependencies), while others have their own.
Plus sign convenience: Dialing + replaces the need to remember the local international access prefix (00, 011, 0011, 810, etc.).

How to dial internationally

Enter your international access prefix:

00 in much of the world
011 in the NANP (+1) region
0011 in Australia, 810 in parts of Eastern Europe/Central Asia, and other variants elsewhere

Enter the country calling code (for example, +33 for France, +81 for Japan, +55 for Brazil).
Enter the local subscriber number (often omitting any domestic trunk prefix like a leading 0).

Tip: On mobile, start with + then the country code (e.g., +44), which the network translates to the correct international access prefix for you.
