International Dialing in Three Steps
Use these quick steps to ring an international number with the right country code and E.164 format, all at low per minute rates.
1. Lead with the Plus Sign
Begin every international number with the plus sign or your device's exit code. The plus signals the network to apply the correct international routing.
2. Add the Country Code
Type the ISO country calling code, for example +44 or +91, ahead of the national number so the call reaches the right country.
3. Follow E.164
Enter the complete national number in E.164 format with no spaces or punctuation. For instance, +441234567890.

What E.164 Means
E.164 is the standard phone number format used across the worldwide phone network. Sticking to it keeps your international calls routing the same way every time.
E.164 Rules
- Open with the country calling code and drop any leading zeros.
- Keep the whole number to 15 digits or fewer, not counting the plus sign.
- Leave out spaces, parentheses, or dashes when you store numbers to dial.
Example
