Get Started with Add-ons

Add-ons are features of the PhoneID API that allow you to get additional information about a phone number along with the base details.

The self-service API only supports the Contact add-on. This add-on allows you to retrieve the name, address, and other contact info associated with the subscriber for the phone number you submit. This page walks you through how to use the Contact add-on in a request and provides other details helpful to using it.

How to Use It

Follow these steps to use the Contact add-on.

Step 1: Enable the Contact Add-on

  1. Log in to your account at
  2. From the left navigation menu, click PhoneID.
  3. From the list of choices that appear under PhoneID, click Settings.
  4. Under the Add-Ons section, turn the switch for Contact Add-On Enabled to Enabled.

Step 2: Send a Request with Add-on Parameters

  1. Prepare a request to the PhoneID API, including all the normal requirements (see Get Started).
  2. Also include the addons request body parameter in the payload.
  3. Also include the sub-property contact, with an empty object as its value.
  4. Send your request.



Authorization: Basic 12345678-9ABC-DEF0-1234-56789ABCDEF0:vjE/ZDfPvDkuGNsuqCFFO4neYIs=
Content-Type: application/json; charset=utf-8
Date: Tue, 31 Jan 2017 14:51:26 GMT
    "addons": {
        "contact": {}



Requests to the PhoneID API that include add-ons must use only the application/json content-type. Basic requests without add-ons have more flexibility on content-type.

Try It

If you have credentials for TeleSign APIs and have enabled this add-on, you can try a test request in the API Explorer. You can also get a code snippet for the request.

  1. Open the reference page for the POST /phoneid/{complete_phone_number} endpoint.
  2. Under the AUTHENTICATION header in the right panel of the page, put your Customer ID in the username field and your API key in the password field.
  3. Under the PATH PARAMS header in the middle panel of the page, enter the complete phone number (including country code) that you want information about in the complete_phone_number field. Do not include any special characters or spaces.
  4. Click Try It! in the right panel to see your transaction. You will be charged the standard rate for your transaction, and you are subject to all compliance rules as appropriate for your transaction.
  5. If you want you can also click the copy icon to the left of Try It! to copy the code snippet displayed. To change the programming language of the snippet, select one of the options under the LANGUAGE header in the right sidebar.

Try It with cURL

You can also try a test request using cURL:

  1. Copy the command below into a text editor
  2. Replace $COMPLETE_NUMBER in the command with the phone number you want information for.
  3. Replace $CUSTOMER_ID with your customer ID from TelePortal
  4. Replace $API_KEY with your API key from TelePortal.
