HOW IT WORKS

A missed call. A verified number

The caller number carries the code. Users enter its last digits to complete verification — they do not need to answer the call.

01

Enter a number

The user enters their phone number in your client’s app or website.

02

Receive a call

Your platform requests a Flash Call through Revicom.

03

Enter the code

The user enters the last 4–6 digits of the incoming caller number.

04

Confirm the number

Your service checks the code and completes the verification.

What is Flash Call verification?

Flash Call verifies a phone number using an incoming call. The last digits of the caller number act as the verification code, which the user enters in an app or website.

Does the user need to answer the call?

No. The code comes from the caller number, rather than a spoken message. The user reads the required digits from the incoming or missed call.

How many digits can the code contain?

The code can contain four to six digits. Confirm the code format when planning your integration and make the instructions clear in your interface.

What if the user cannot complete verification?

Offer an SMS alternative. You can configure the fallback on your side or discuss a Revicom-managed setup if you use us as your SMS Hub.

Where is Flash Call available, and what does it cost?

Send us your destination countries and expected traffic volumes. We will review availability and provide the rates relevant to your planned traffic.

Can existing Revicom clients use SMPP?

SMPP is an available connection option. Contact our team to review how Flash Call can fit your existing Revicom integration.
