Country Code List - Alphabetical Listing by Country or Region

What is the format of an international phone number?

The international format for a phone number is typically written as:

[Country Code] [Area Code] [Local Number]

Here's a breakdown of each part:

• + (Plus Sign): This is the international prefix, indicating that the number is in international format.
• Country Code (CC): A 1-3 digit code that identifies the country where the phone number is located. For example, the country code for the United States is +1, while the United Kingdom’s is +44.
• Area Code (AC): A code that identifies a specific geographic region within a country. The length of the area code varies by country, but it's usually 1-3 digits. In some countries, the area code is not used or is incorporated into the local number.
• Local Number (LN): The unique phone number assigned to a specific phone line or device.

Examples of an international phone number

+1 202 555 1234 (United States)

+44 20 7183 8750 (United Kingdom)

+61 2 9876 5432 (Australia)

Note that the international format may vary slightly by country and phone number type (e.g., landline, mobile, toll-free).

How to Identify the Country of a Phone Number?

Identifying the country of a phone number can be tricky, but there are a few ways to do so. Here are some steps you can follow:

• Every country has a unique country code, a series of numbers that precedes the phone number. You can identify them using a tool like the one you are viewing online now.
• The country code is usually 1-3 digits long.
• You can look up the country code online or check the phone number against a list of country codes.
• For example, the country code for the United States is +1, while the United Kingdom’s is +44. Other examples of country codes and phone number formats:
  • United States: +1 (XXX) XXX-XXXX
  • Canada: +1 (XXX) XXX-XXXX
  • Australia: +61 XXXX XXXXXX
  • India: +91 XXXX XXXXXX

Which Country Uses the +1 Prefix?

The country that uses the +1 prefix is the United States, as well as its territories, and several Caribbean and Pacific island nations. The North American Numbering Plan (NANP) uses the +1 prefix for these countries and territories, which include:

• United States
• Canada
• Many Caribbean islands, such as the Bahamas, Bermuda, and the Cayman Islands
• Some Pacific island nations, such as American Samoa and Guam

This means that when calling a phone number in one of these countries or territories from outside the region, you would use the +1 prefix, followed by the area code and the local phone number.
