Phone Number Formatter
Phone Number Formatter Overview
Format and validate phone numbers
The Phone Number Formatter & Validator is an essential utility for verifying and standardizing international phone numbers. Leveraging the industry-standard Google libphonenumber library, it parses raw input to determine the country of origin, validity, and line type (mobile vs. landline). The tool outputs the number in multiple formats: International, National, and the critical E.164 format required by many APIs (like Twilio and AWS SNS). Use this tool to clean up your customer data, debug SMS delivery issues, or ensure your contact forms are accepting valid inputs.
