Perform Number Deactivation Check

This page shows you how to send a request to find out the activation status of a phone number using the Number Deactivation API. The Number Deactivation API will return basic details about whether the number has been deactivated, when, and by which carrier the phone number was deactivated based on carriers’ phone number data and TeleSign’s proprietary analysis.

The fastest way to try out this API is with TeleSign’s Number Deactivation API Explorer.

Number Deactivation API Explorer
NOTE: When using the Number Deactivation API Explorer, you will be charged your contracted rate for each transaction. The time shown in ms is not indicative of regular transmission rates, and only applies to the Number Deactivation API Explorer.
SettingsHeaders [1]Auth[basic]Code Generation
Send requests directly from the browser (CORS must be enabled)
Path Params
1 path param not set
complete_phone_number
$$.env
No $$.env variables are being used in this request.

Use these instructions with the Number Deactivation API Explorer (above) to perform a number deactivation check and get a code snippet for making the request in the language of your choice.

  1. Click the Auth [basic] tab and for Username add your Customer ID. For Password add your API key.
  2. Click the Settings tab and in the complete_phone_number field, enter your phone number with the country code and no special characters or spaces.
  3. Click Send.
  4. Click the Code Generation tab and use the Language and Library drop-downs to choose the language you want your code snippet in.
  5. After you send your request, look through the JSON response and save the value for the reference_id parameter. You will need this to receive transaction status results, described on the Obtain Transaction Status Results page.

Congratulations! You’ve performed your first number deactivation check using TeleSign’s Number Deactivation API and generated a code snippet!
