How many countries are supported?
We support phone number validation for 200+ countries and territories worldwide, including all major regions.
What phone number formats can I submit?
Submit numbers in any format - with or without country code, spaces, dashes, or parentheses. We parse and validate automatically.
Can you detect if a number is mobile or landline?
Yes, we return line type information including mobile, landline, VoIP, toll-free, and premium rate classifications.
What is E.164 format?
E.164 is the international phone number standard (e.g., +14155551234). It's required by most SMS and calling APIs.
Does it return the carrier name?
No. Line type (mobile, landline, VoIP, toll-free) is derived from the number itself. Carrier names and HLR lookups need a live network query, which this API does not make.
Does validation check if the number is actually in use?
We validate format and structure. To check if a number is actually reachable, you would need to send a verification SMS or call.
