Phone verification API for incoming SMS
Automate the receiving side of phone verification for accounts and workflows your business is authorized to manage. Our service supplies the number and incoming SMS; your own application remains responsible for validating the code.
Verification, validation and OTP sending are different
Phone-number validation checks a number's format or line information. An OTP-sending API messages your own users. This page concerns a third job: supplying a number and receiving the SMS that another authorized service sends to it.
Knowing which job you need prevents the wrong integration. Tell us the target service and country so we can confirm whether inbound verification supply fits your workflow.
A clear activation lifecycle
Your integration requests a number, waits for the incoming SMS, receives the full message and then completes or cancels the activation according to its status. Keeping each activation tied to one workflow helps avoid mismatched codes.
Availability and cancellation terms depend on the selected service, country and number type.
Physical SIM and virtual options
Some target services treat number types differently. We offer virtual numbers and physical SIM options across 189 countries, but no provider can promise acceptance by every third-party platform.
Run a sample using the real service and country you intend to support before ordering daily volume.
Business onboarding
Contact the sales manager with your service list, countries, preferred number type and expected volume. We confirm current availability, arrange API access and agree a test before a larger supply contract.
Frequently asked questions
Does this API validate whether a phone number is active?
No. It supplies numbers and receives inbound verification SMS; it is not a phone-number lookup or validation database.
Does it send OTP codes to my customers?
No. Your own platform must generate, send and validate customer OTPs. This service handles inbound SMS on supplied numbers.
Can I test a specific service and country?
Yes. A small test is recommended before regular supply because acceptance and availability vary.
