Verification products to secure best user experience and protect your Apps
Missed call verification
With this cost-savvy verification technique, users receive a missed call from a random number. The 4 last digits of this random number are used as a passcode.
Strong SMS verification
One-time SMS passcodes are sent via our extensive mobile carrier network to ensure best delivery rates at optimal costs.
Phone call verification
Passcode is delivered as a voice message via phone call, reaching both mobile and landline numbers.
Caller ID verification
Another cost-saver, where the user receives a random phone number to call. They complete verification by dialing this number from the number that needs to get verified.
HLR lookup
Every phone number is verified against international databases to ensure it’s validity and identify the type (mobile or landline).
Multiple carrier support
Connected directly to 120 voice and SMS providers worldwide, Apifonica ensures failover delivery of verification calls and messages at the best rates.
How complex Voice & SMS phone verification works
Phone number validity check
When users enter their phone number for the first time (i.e. during a registration process), Apifonica instantly checks international databases to define if the number is valid and whether it is a mobile or landline number.
Landline number verification
An SMS cannot be delivered to a landline number, so Apifonica converts the passcode into a voice message using text-to-speech technology, calls the user and reads them the passcode.
Mobile number verification
Apifonica delivers verification passcode via SMS. If undelivered or users provide no input, Apifonica calls the number and reads out the passcode.
Passcode input
Users input the passcode to complete the transaction, which is then verified by the company’s system.
