Question 1

What formats does the phone number parser support?

Accepted Answer

The parser supports all major international phone number formats including E.164 (+12025550100), international (+1 202-555-0100), national (202-555-0100), and RFC3966 (tel:+1-202-555-0100). You can enter numbers with or without country code — if you omit the country code, set a default country to help the parser interpret the number correctly.

Question 2

What is the difference between E.164 and international format?

Accepted Answer

E.164 is the strictest machine-readable format: a plus sign followed by only digits, no spaces or dashes (e.g. +12025550100). International format is the human-readable equivalent with spaces and punctuation (e.g. +1 202-555-0100). E.164 is required by most telephony APIs (Twilio, AWS SNS, etc.), while international format is for display.

Question 3

What phone number types can be detected?

Accepted Answer

The parser can identify: MOBILE, FIXED_LINE, FIXED_LINE_OR_MOBILE, TOLL_FREE, PREMIUM_RATE, SHARED_COST, VOIP, PERSONAL_NUMBER, PAGER, UAN, VOICEMAIL, and UNKNOWN. Type detection accuracy varies by country — some countries (like the US) cannot distinguish mobile from fixed-line numbers without carrier lookup.

Question 4

What is the difference between 'valid' and 'possible' for a phone number?

Accepted Answer

A 'possible' number has the right length for a phone number in that country but may not be assigned. A 'valid' number passes full validation including format rules, prefix checks, and length — it is far more likely to be a real, dialable number. Always use validity (not just possibility) when filtering user-submitted phone numbers.
