A zero-dependency Node.js wrapper around Google's libphonenumber library for parsing, formatting, storing, and validating international phone numbers. It makes the Closure-compiled JavaScript port of libphonenumber easy to require and use in Node.js projects.

Use cases

• validate international phone numbers in a node.js app
• parse raw phone number strings into country code and national number
• format phone numbers as E.164 or RFC3966
• standardize user-entered phone numbers before storing them
• look up carrier and region metadata for a phone number
• normalize phone numbers for SMS sending

When to choose

• you need Google's libphonenumber functionality in Node.js without fighting the Closure library
• you want a zero-dependency, regularly updated phone number library
• you need reliable international phone parsing, formatting, and validation server-side

When to avoid

• you are not on Node.js (use the official libphonenumber ports for Java, C++, or the browser directly)
• you only need lightweight country-code validation and want a smaller library
• you need TypeScript types out of the box (they live in a separate @types package)
