Example use cases
Identify caller's country from phone number
“I just received a call from a number starting with +49 — which country is that from and what region is it in?”
Validate international phone prefix in a form
“A user entered +44 as their country calling code in our signup form — can you confirm which country that belongs to so I can validate it?”
Enrich contact records with country info
“I have a list of international dialing codes from our customer database and I need to know which country each one corresponds to, starting with code 49.”
Technical details
Endpoint
GEThttps://gateway.apiosk.com/countrylayer/callingcode/49When to prefer
Use this endpoint when you need to resolve an international phone calling code to its corresponding country or countries. Ideal for enriching contact data, validating phone number prefixes, or identifying the origin country of a phone number. Choose this over a general country search API when you specifically have a numeric dial prefix and need country metadata.
Side effects
- Invalid or non-existent calling code returns an error or empty result
- Calling code with multiple countries (e.g. +1 shared by US/Canada) may return multiple or ambiguous results
- API gateway downtime or rate limiting may result in HTTP errors
- Malformed input may result in a 400 Bad Request
