What is E.164 format?

E.164 is the international standard telephone numbering plan defined by the ITU. An E.164 number starts with + followed by the country calling code and the national (significant) number — with no spaces or punctuation. Example: +14155551234.

How does the tool detect the country?

The tool matches the leading digits after the + or 00 prefix against a database of country calling codes using longest-prefix matching. For example, +44 is matched to the United Kingdom, +91 to India, and +1 to the US/Canada NANP region.

Can it parse multiple phone numbers at once?

Yes — enter one phone number per line and the parser will analyze each one separately, producing a structured report for each.

Is my phone number sent to a server?

No. All parsing happens in your browser. Your phone numbers are never uploaded, stored, or transmitted anywhere.

What is Phone Number Parser?

A phone number parser analyzes an input phone number and extracts structured information: the country of origin (via dialing code matching), whether it's a mobile, landline, toll-free, or premium-rate number (via prefix hints), the national number portion, and the E.164 international format. All parsing uses regex and prefix matching — no external libraries needed.

This tool supports dozens of countries and handles common input formats like (555) 123-4567, +44 7911 123456, and 1-800-555-1234. Multiple numbers can be parsed simultaneously, one per line.
