Phone Number Parser

Reference

What is a phone number parser?

A phone number parser takes a raw phone number string and extracts structured information: the country, the national number, and formats it in standard representations. This tool detects the country from the dialing prefix, validates the number length against known country rules, and formats the number in E.164 (e.g. +14155551234), international (e.g. +1 415 555 1234), and national (e.g. (415) 555-1234) formats. It also provides a best-guess on whether the number is a mobile or fixed line based on common prefix patterns.

Phone number formats explained

E.164 — the ITU standard: a + sign followed by the country code and subscriber number, with no spaces or formatting. Maximum 15 digits. Used by telecom systems and APIs (e.g. +14155551234). International — E.164 with spaces for readability (e.g. +1 415 555 1234). National — the format used within the country, often with a trunk prefix like 0 (e.g. (415) 555-1234 in the US, 0415 555 1234 in Australia).
