How this service works
Country for an ITU E.164 calling code or international number prefix, such as +44 or +1 876; flags shared codes.
Output
Returns an object with the resolved calling code, a list of matching countries (each with name and ISO alpha-2 code), a list of all countries that share the code if applicable, a plain-language summary, verdict, and optional disclaimer and attribution fields.
Example use cases
Identify origin of unknown caller
“I got a call from a number starting with +234 — what country is that from, and is that code shared with other countries?”
Validate phone number country prefix
“Before I send an SMS to +1 876 555 1234, can you confirm which country the +1 876 prefix belongs to?”
Enrich contact database with country info
“I have an international phone prefix +49 in my CRM — look up which country that belongs to so I can tag the record correctly.”

Endpoint
GEThttps://country-codes-iso.x402tookit.com/calling-code?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify which country (or countries) an ITU E.164 calling code or phone number prefix belongs to, especially when dealing with shared codes like +1. Prefer this over a generic country lookup when the input is a dial code rather than a country name, ISO code, or TLD.
Side effects
- Unrecognised or malformed code returns an empty countries array with an explanatory summary
- Ambiguous prefixes shared by many countries will list all of them in sharedWithAll rather than a single match
- Missing 'code' query parameter results in a validation error
- Non-numeric or improperly formatted input (e.g. letters) may return no match
