1. What is Portability Check?
Portability Check allows you to perform a phone number check to clean up and update your customer database before you initiate customer communications. When you query a phone number via our Portability Check API, you’ll receive the query result containing validated information related to the phone number. For example to which country and operator the number is registered, and whether the phone number is formatted correctly or not.
It’s recommended to perform such a check on a regular basis to make sure your customer database is up to date. Even better is to perform the check prior to sending an SMS or making a call.
That’s important, as it can be a major cost saving factor to know which operator the number is registered to and whether the number is correct. Portability Check can also minimize failed delivery attempts by distinguishing between number types, such as mobile and landline numbers.
PRO TIP: Portability Check is part of our Number Information services. tyntec’s Portability Check obtains data directly from local number portability databases (in countries where portability is supported) and utilizes live network information from tyntec’s global network.
For use cases requiring more contextual, real-time data, tyntec’s Number Verification service offers even more possibilities to minimize message loss and unsuccessful call attempts. It verifies phone numbers in real time and provides additional key information about each phone number, such as the subscriber status and roaming data.

Click ‘Add a new account’ near the top left of your screen. You will be able to select an API / protocol.
To finalize the setup of your account, you need to choose at least:
- API / Protocol (RESTful API or ENUM)
- Source IP Address #1
You can also add a second ‘Source IP Address.’ For the RESTful API you can also add a ‘Respond back URL.’


For this part, you'll probably need some developer's expertise.
