Phone Number Formatter
A phone number formatter strips non-digit characters and applies a readable layout — the familiar (xxx) xxx-xxxx format for 10-digit US/Canada numbers, and a generic grouped "+digits" layout for other lengths. The (xxx) xxx-xxxx layout is specific to the North American Numbering Plan shared by the US, Canada, and several Caribbean nations, which is why a 10-digit number formats that way by default while other-length numbers fall back to a generic grouped layout rather than guessing at a country-specific format that might be wrong.
How it works
- Enter a phone number in any format.
- Read the formatted result.
Formula Strip non-digits; 10-digit (or 11 with leading 1) numbers get (xxx) xxx-xxxx; others get grouped +digits
Frequently asked questions
Does this validate international numbers correctly for every country?
No — full international formatting needs a large per-country metadata database (like Google’s libphonenumber) this site doesn’t ship. US/Canada 10-digit numbers get the familiar layout; other lengths get a generic grouped format.
Does this tell me if a number is real or reachable?
No — it only reformats digits you provide; it does not verify the number exists or is in service.
What if I include the country code?
A leading "1" on an 11-digit number is recognized as the US/Canada country code and formatted accordingly; other country codes fall back to the generic grouped format.
Is my phone number sent anywhere?
No. Formatting runs entirely in your browser.
Does this handle extensions, like "x1234"?
No — every non-digit character is stripped before formatting, so an extension's digits get merged straight into the main number instead of kept separate. Format the base number here and add the extension manually afterward.
