Phone Number Formatter API

What it does

Phone Number Formatter parses a phone number and returns it in common formats you can store, display, or validate against. Send a number and optionally a country code, and get back the parsed result with e164, international, national, valid, region, country_code, and the original input.

Use it when you need to normalise user-entered numbers before saving them to a database, comparing them across systems, or preparing them for SMS and calling workflows. The country parameter defaults to US, which helps when the input is missing an explicit international prefix and you still need a consistent parse.

The response is straightforward: valid tells you whether the number can be interpreted, while the format fields give you the canonical versions for downstream systems. e164 is useful for transport and storage, national is better for local presentation, and international gives you a human-readable cross-border format.

Phone Number Formatter fits into signup forms, contact import tools, CRM pipelines, and any workflow where phone numbers arrive in different shapes and need to be standardised before use.
