Country Calling Codes

Gives you programmatic access to international dialing data without hunting through telecom standards docs. You get country calling codes, ISO country codes, E.164 formatting rules, regional information, trunk prefixes, and NANP area codes for North America. Reach for this when you're building phone number validators, formatting international numbers for display, or need to parse and validate user input in contact forms. It's the reference data you'd otherwise scrape from Wikipedia or maintain in a static JSON file, exposed through a queryable interface. Useful for CRM integrations, communication platforms, or any app that handles phone numbers across multiple countries.
