Phone Number Parser

E.164 is an international telephone numbering plan defined by ITU-T. It specifies a maximum of 15 digits starting with a country code, with no spaces or punctuation. For example, a US number would be +15551234567.

The parser matches the leading digits of the phone number against a built-in lookup table of approximately 30 common country calling codes. It tries longer codes first (e.g., +44 for UK before +4 for anything else) to find the best match.

The parser handles many common formats including +1-555-123-4567, 15551234567, (555) 123-4567, 555.123.4567, and international formats with country codes. It strips all non-digit characters (except a leading +) before parsing.

The type detection is a best guess based on common patterns for each country. For the US, numbers starting with area codes followed by typical mobile prefixes are classified accordingly. For exact results, a full carrier database lookup would be needed.

Yes — numbers without a country code are assumed to be US/Canadian (+1) numbers. If the number has 10 digits, the parser will prepend +1 automatically. For other countries, include the country code for accurate parsing.
