Validate and Format Phone Number API

What it does

Phone Number Validator parses and validates phone numbers, returning E.164 and country-aware formats you can store or compare reliably. Send a phone value in E.164 form or national format; for national-format numbers, include the optional country hint as an ISO alpha-2 code.

The response tells you whether the number is valid and includes the normalized e164 value when available. It can also return the original input, country, calling_code, country_code, national_format, national_number, and international_format, so you can standardize user-entered contact data without guessing formatting rules.

Use Phone Number Validator when you need to clean signup forms, deduplicate contacts, or accept local phone entry from multiple countries while keeping one canonical representation in your database. It is especially useful before sending SMS, building user profiles, or enforcing per-country phone rules at the edge of your app.

If you only need a validity check, use the valid flag. If you need normalization, use the formatted fields to display or persist the number in a consistent way.
