That’s where the international phone number format comes into play.

This standardized approach helps bridge the gap, making it easy to dial and connect with people worldwide without having to worry about regional quirks.

The international phone number format, especially the E.164 standard, solves this by creating a universal structure that’s easy to use worldwide.

This guide covers everything you need to know about international phone formatting, why it matters, and how adopting it ensures your calls and messages reach the right people, no matter where they are.

What Exactly Is International Phone Number Format?

The international phone number format is a standardized way of representing phone numbers to ensure compatibility across countries and networks. The primary standard used worldwide is the E.164 format, established by the International Telecommunication Union (ITU).

This format structures phone numbers to include only essential details for international dialing, eliminating any unnecessary symbols or local codes.

E.164 is the official international standard for phone numbers. It establishes a single structure to make every number unique and globally recognized.

In the E.164 format:
  • The maximum character length is 15 digits.
  • Numbers begin with the country code, followed by the area or network code, and the subscriber number.
  • Symbols and spaces (such as dashes or parentheses) are omitted.
For example, the E.164 format for a New York number might look like this: +12125550123.

Why Is It So Important?

Seamless communication across borders is essential for both personal and business purposes.

Standardized phone number formats enable this smooth exchange, ensuring that calls and messages reach the intended recipient no matter where they are in the world.

Without a universal structure, communicating internationally could become a puzzle of incompatible digits and uncompleted connections.

So let’s discuss the international phone number format, its importance, how to structure numbers for international use, and best practices for keeping your contact information globally accessible.

Examples:

An international phone number typically follows the structure:

+[Country Code] [Area Code/Network Code] [Subscriber Number]

Here’s how it looks for different countries:
  • United States: +1 202 555 0185
  • United Kingdom: +44 20 7946 0958
  • Australia: +61 2 9374 4000
  • India: +91 98765 43210
  • Canada: +1 416 555 0199
  • France: +33 1 45 67 8901
  • Germany: +49 30 1234567
  • Brazil: +55 11 91234 5678
  • Japan: +81 3 1234 5678
  • South Africa: +27 21 123 4567
  • Mexico: +52 55 1234 5678
  • Italy: +39 06 123 4567
  • China: +86 10 1234 5678
  • Russia: +7 495 123 4567
In the above examples:
  • The + symbol signifies an international call.
  • The Country Code is unique to each country (e.g., 1 for the US, 44 for the UK).
  • The Area/Network Code may vary within the country.
  • The Subscriber Number is the individual’s local phone number.
This consistent structure makes it easier to call internationally by clearly identifying the country and region before the actual phone number.

E.164: The Format Accepted Internationally

Each country has unique dialing rules and phone number lengths, which can vary by region. For instance:
  • North America: Uses a 10-digit format with a 3-digit area code and 7-digit subscriber number.
  • Europe: Countries like France and Germany use variable-length codes, often requiring the full city code even for local calls.
  • Asia: Diverse formats exist, from Japan’s varying area code lengths to India’s standardized area codes.

Standardized Way

To streamline communication, it’s recommended that all phone numbers be formatted in the E.164 format when stored in a database or used for automated calling and messaging systems.

For example, instead of (202) 555-0185 for the US, use +12025550185.

This ensures that your contact details are recognized universally, removing ambiguities caused by local formats.
