How phone number validation works

Phone number validation checks whether a number conforms to the numbering plan for its country. This includes verifying the country code, checking the total digit count, and validating the area/subscriber number format.

This tool performs basic structural validation. It checks the country code, digit count, and common format rules. For production applications, use a library like libphonenumber for comprehensive validation.

Common validation issues

Missing country code: Always include +1, +44, +91, etc. Without it, the number is ambiguous.
Wrong digit count: US numbers are 10 digits (after +1), UK mobiles are 10 digits (after +44), India is 10 digits (after +91).
Leading zero confusion: Many countries use a leading 0 for domestic dialing (e.g., 020 in the UK). Drop the 0 when adding the country code: +44 20, not +44 020.
