Enter a phone number and it is reformatted as you type.
What this is
This phone number formatter takes a number in any common form and shows it in the four formats a system is likely to want - E.164, international, national and RFC 3966's tel: - each with its own copy button, with no claim made about whether the number is valid or what kind of line it is.
A phone number is written differently depending on who is asking: E.164 (+14155552671) is the one format almost every system - an API, a database, a carrier - takes without complaint; international and national are how a person writes it between and inside the number's own country; and RFC 3966's tel: scheme is what a link or a SIP header carries. This tool converts between all four without checking whether the number is actually assigned.
How to read the result
The facts row names the country the number belongs to. Each format below it - E.164, international, national and tel: - has its own copy button, so you can take exactly the one your system needs without retyping or re-escaping it.
Reshaping a number does not confirm it is a real, assigned range on its own, and a malformed number breaks every check further down the line; see sending an SMS that arrives for why that matters before segment pricing, sender-name or A2P checks even start.
Common mistakes
What goes wrong most often, and how to tell.
- Typing a national number with no country code and no hintA number typed without its +country code can be reshaped into more than one country's formats, depending on which country it belongs to - set the hint below, or start the number with its own +code, so there is only one country to format it for.
- Assuming a formatted number is a valid oneThis tool reshapes whatever you give it into every common format; it does not check whether the number is a real, assigned range. Use the phone number validator for that.
Questions
What people ask about this tool.
- No. This tool only reshapes a number into E.164, international, national and tel: form. For a check against real assigned ranges, use the phone number validator.
- A national number on its own is ambiguous - the same digits can belong to more than one country. A leading + country code carries that information itself; without one, the two-letter country field supplies it.
- RFC 3966's tel: scheme is what a clickable phone link or a SIP header carries - pasting it as an href lets a phone or softphone dial it directly.
- No. Everything is reshaped in your browser, against the metadata that shipped with this page itself; nothing you type is ever sent anywhere.
