Phone Number Validator
Validate basic international phone syntax locally; this tool does not check country allocation or whether a number can be reached.
A QUICK WALKTHROUGH
How to use this tool
- Enter a number beginning with + and a country code.
- Optionally remove spaces, hyphens, and parentheses.
- Review the syntax result; this is not a carrier or country validator.
Syntax only
Accepted form is + followed by 8–15 digits, with the first digit from 1–9. This does not verify country allocation, ownership, reachability, or libphonenumber rules.
Local processing
The number is checked in your browser and is not uploaded or stored.
