Toll-Free Numbers Verification API

Overview

A toll-free number can be used to send messages in US & Canada once it passes an additional verification process. Users who don’t verify their toll-free numbers will be blocked from sending messages as of November 8, 2023.

A verified toll-free number ensures that the business owning the number is identified, and that the message's content has been reviewed and does not oppose the Disallowed Content Policy. This process ensures better deliverability and less filtration.

To set up a new channel to send SMS messages using a toll-free number the following steps are required.

API Access

The following API requests can only be made using a valid access key, and attached to an access role, with an access policy that at least specifies the permissions to the resources outlined in each section below. Learn more about API access.

Find an available number

If you do not already have a US or Canadian toll-free number available in your workspace you can find one to purchase.

The following example will return the first available toll-free number required for use with toll-free number registration. Country can be either `US` or `Canada`.

curl --location 'https://nest.messagebird.one/workspaces/<your-workspace-id>/numbers-available?limit=1&country=<your-selected-country>&type=tollfree' \
--header 'Accept: application/json' \
--header 'Authorization: AccessKey <your-access-key>'

Purchase a number

Once you have found an available number you can purchase this by providing the number (in E.1624 format) and the country (using a two digit ISO code).

A successful request to this endpoint will start a recurring monthly subscription based on the monthly cost of the number.

The following example will purchase the number if it is still available and you have sufficient balance in your workspace wallet. Provide number in E.1624 format and country in 2 digit ISO code (e.g. US).

curl --location 'https://nest.messagebird.one/workspaces/<your-workspace-id>/numbers' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'Authorization: AccessKey <your-access-key>' \
--data '{
  "numbers": [
    {
      "number": "",
      "country": ""
    }
  ]
}'

Submit a verification application for a toll-free number(s)

Before you can use a toll-free number to send SMS messages, you must submit a toll-free number verification request and wait for it to be approved.

You can submit one toll-free number per verification request.

You are not allowed to submit the same number twice, unless the previous submission was resolved with status Rejected or Verified.
