About Phone Number Formatter
We built this tool to solve a common frustration: phone number formats that don't work across different platforms.
Our Mission
Phone Number Formatter exists to make phone number formatting simple, free, and accessible to everyone. Whether you're managing a CRM, building a contact form, or just need to format a number quickly, our tool provides instant, accurate results in multiple international formats.
Why We Built This
Inconsistent phone number formats cause real problems:
- CRM systems create duplicate records for the same contact
- Click-to-dial features break when numbers aren't standardized
- International calls fail due to incorrect formatting
- Data migrations between platforms lose phone number consistency
- Manual reformatting wastes valuable time
How It Works
Our formatter uses libphonenumber-js, a JavaScript port of Google's libphonenumber library. This battle-tested library powers phone number validation and formatting for millions of applications worldwide. It understands the formatting rules for every country and ensures your numbers are valid and properly formatted.
