TeleSign PhoneID Monitoring enables you to track your end-users’ phone numbers for important events, helping you identify potential fraud and then take necessary steps to protect your users and your business.
Every 24-hours, if any of these events occur, TeleSign sends you an alert you can use to take further action.
The service tracks the following events for your subscribed phone numbers:
- Number Deactivation - The user disconnects their phone number completely.
- Number Porting - The user keeps their phone number while changing carriers.
- Number Change - The user keeps their carrier, but changes the phone number tied to their account.

How it Works
The operation of the product occurs in three steps.
Step 1: Subscribe Phone Numbers
When your account is opened, we create a dedicated directory for you on an SFTP site and send you access details for that site. You can then subscribe new phone numbers for monitoring at any time by uploading a subscription file to this directory. The service checks for new subscription files once per hour. You can also unsubscribe numbers using this same file.
Step 2: Process Subscription File
If there are problems that prevent processing of the entire subscription file, we upload a rejection file to your SFTP directory that gives you details about why the file is rejected.
If there are problems with the processing of individual records in the subscription file, we send you an error file with details about each record-level error.
If the file is not rejected, each new record successfully processed results in the new phone number you specified being added to the monitoring DB (or if an unsubscribe operation is specified, removing it from the DB).
It can take up to 90-days from the time the service receives an unsubscribe request for a phone number for that operation to be processed. So you may still receive alerts for that number in the meantime.
Step 3: Send Alerts
The service checks with carriers on an ongoing basis for tracked events, for all subscribed phone numbers in the monitoring DB. Every 24-hours, if any of these events occurred over that period for a subscribed number, an alert file is uploaded to your dedicated SFTP directory with details about each event. We recommend that you create a process in your system to check periodically for the appearance of these alert files, so you can take appropriate action.
