Error message: We weren't able to approve your SMS registration

Resubmit an SMS registration that fails due to a mismatched EIN

For US Customers:

Exclamation point IconImportant: Our SMS marketing tools are only available to US customers (excluding Puerto Rico and the US Virgin Islands) with a valid 9-digit Tax ID Number (TIN), or an Employer ID Number (EIN) for businesses assigned by the IRS. Sole proprietors who are the only employee do not need to enter Employer ID Number (EIN). Contacts with phone numbers from Puerto Rico can join your list and receive text messages. Learn more.

 

For Australian Customers: 

Exclamation point IconImportant: Our SMS marketing tools are only available to Australian customers with a valid 11-digit Tax ID Number (ABN). Learn more.

After you submit the SMS registration form, our SMS messaging provider checks your registration information against official databases. If the information you entered doesn't match, your registration can be rejected. 

 

The status of your Business ID

It can take some time for your business registration to become active. If you submit your SMS registration and your business ID hasn't been processed yet, it can cause problems with your registration.

 

For the US: 

Newly created EIN numbers can take between 2 weeks and 90 days to populate in the IRS database, which is referenced by The Campaign Registry (TCR), the third-party that helps mobile carriers verify SMS marketing traffic from business phone numbers. It's a good idea to wait at least 14 days after the date you receive your new EIN before registering for SMS to prevent a failed registration because your EIN hasn't been updated in the IRS database yet. Learn more.

 

For Australia: 

If all required information is submitted, you will usually receive online notification of your ABN right away. If information is missing or cannot be verified, an ABN will not be allocated immediately. Your application will be processed manually, which may take up to 28 days. To check the progress, contact the ABR.


If your registration fails the first time

Clock IconSave time: Have a recent tax form handy to ensure your ABN or EIN, business name, and business address exactly match what you enter in the SMS registration fields. (Alternatively, you can search your state's business entity database for the information if you don't have access to a tax form.)

 

When your registration is rejected, a banner appears on both the SMS tab in your account settings and on the SMS dashboard. To resolve the error, you have to resubmit the SMS registration.

  1. Click on the arrow next to the account profile name in the top right-hand corner and select Settings from the drop-down menu.

    Note:
    Alternatively, you can click Channels > SMS (not pictured) and skip to step 3.

  2. From the My Account dashboard, click the SMS tab.
  3. Click the Register again button.


     
  4. Fill out the registration information again and make sure that your organization name, physical address, and business ID exactly match what is on your tax form.

    • For the US: An EIN is not required; however, if you have an EIN, you must use it to register. You also need a valid website to complete the registration.

    • For Australia: If a website is unavailable, a link to a social profile can be provided.

  5. When you're ready, click the Submit registration button in the lower right-hand corner to resubmit your registration.

Navigate to your account settings. Alternatively, you can click Marketing channels > SMS and skip to step 3.
