What is the E.164 phone number format?

E.164 is the international standard: a + followed by the country code and national number with no spaces — e.g. +15551234567. Databases and APIs expect this format. This tool outputs it for every parsed number.

How do I format a phone number for international dialing?

Paste it into the parser above and read the "international" format — e.g. +92 300 1234567. That is exactly what you dial from abroad (replacing the + with your carrier's international prefix if needed).

Can this tool tell which country a phone number is from?

It detects the country from the +country code using a built-in dial-code table (e.g. +1 → US/CA, +44 → UK, +92 → PK). Without a country code it uses your selected default country. It cannot identify the carrier or whether the number is active.

Why is my number marked invalid?

Usually the digit count does not fit the detected country's national number length (e.g. 10 digits for US, 10 for PK mobiles after the leading 0). Double-check for missing digits or a wrong country code.

Is this as accurate as libphonenumber?

No — and it is honest about that. This is a lightweight heuristic parser: correct for standard numbers in the 6 supported countries, but it cannot do carrier detection, region-level validation, or the hundreds of edge cases the full libphonenumber database handles.

Phone Number Parser — Parse & Format Phone Numbers

What is Phone number parser?

Phone Number Parser — Parse any phone number free online — get E.164, international, and national formats with country detection. Heuristic parser, nothing uploaded.

A lightweight heuristic parser written for this tool: it strips formatting characters, extracts an explicit +country code when present (matched against a built-in country-code table), otherwise applies the selected default country. Validation is shape-based (expected national digit ranges per country), not a carrier lookup. All processing is client-side; nothing is uploaded. This is intentionally not libphonenumber — lighter, but less precise.
