Frequently Asked Questions
What is E.164 format?
E.164 is the international telephone numbering plan that defines the format for phone numbers: + [country code] [national significant number], with a maximum of 15 digits.
What does a valid phone number mean?
A valid phone number matches the expected format and length for its country. Note that format validity does not guarantee the number is actually in service.
How does auto-detect work?
The tool analyzes the country code prefix (+1, +44, +91, etc.) to determine the country. If no prefix is entered, it validates against the selected country's format.
