Viteza FAQ

Within your account, you get access to three different services:

  • Live – Our Real-time Lookup service
  • Velocity – Our superfast Number Portability Lookup service which tells you the current network to which a number is connected
  • TeleShield – Our Teleshield routing queries to confirm number validity, service type (e.g., mobile/fixed), and up to 30 additional service clarifications

The Viteza User Guide provides information on how to access the coverage and pricing for each service that is available.


There are several use cases for real-time queries. If your business relies upon customer information containing mobile numbers then you’ll know how important it is to be able to contact them. Retail businesses, call centres and sales departments may regularly want or need to contact their customers whether via a mobile telephone call or via SMS (text message). Having accurate and up to date information on whether a number is active makes your efforts more cost-effective but also compliant with GDPR and other regulatory bodies.

SMS Messaging companies sending large volumes of 2FA (Two-factor authentication) messages or OTP (One Time Passcodes) also need to know that a mobile number is active as well as obtaining the correct and least cost routing for the messages they are sending on behalf of banks, e-commerce sites, airlines and ride-sharing companies around the world.

You can find instructions on use of the service and topping up your balance in the Viteza User Guide.
