# Country Calling Codes API

Looks up a country by calling code (+44), ISO region (GB) or English country name and returns the calling code, every region that shares it.

Looks up a country by calling code (+44), ISO region (GB) or English country name and returns the calling code, every region that shares it, national number lengths, trunk and international dialing prefixes, example numbers and the leading digits of mobile and fixed-line numbers where the numbering plan defines them. Derived from open libphonenumber metadata and CLDR country names; it describes numbering-plan rules, not who is assigned a number.

## Questions

### How much does Country Calling Codes cost?

1 credit per lookup (an unknown code, country or name is free). Credits come out of the one balance shared by every LookValid product.

### Am I charged when nothing is found?

No. When the lookup runs and finds nothing, it returns found: false and costs 0 credits. An error costs nothing either.

### How long are results cached?

For 7 days, per account. Repeating the same lookup inside that window returns cache_hit: true and costs 0 credits.

### Which API key do I use?

The same key as every other product. Send it as a Bearer token in the Authorization header. Email hello@lookvalid.com and we set up your account and send the key.
