Recent rulings and regulations aimed at enhancing trust around SMS messaging now require all customers using SMS messaging to register for A2P 10DLC.

This applies to all major U.S. telecommunications carriers and is not specific to SourceWhale and our messaging provider Twilio.

Beginning July 5, 2023, all SMS messages sent to U.S. phone numbers using 10DLC phone numbers—i.e., 10 digit US phone numbers such as (111) 111-1111—must be sent via a registered application-to-person (A2P) campaign.

Messages sent using unregistered phone numbers will be subject to a gradual increase of message blocking, ultimately leading to a full block of all unregistered U.S.-bound messages sent after August 31, 2023.

Admins can register for A2P 10DLC from directly within SourceWhale.


Registration Process

  1. Go to SourceWhale Admin settings.

  2. Click the “Compliance” tab.

  3. Fill in the form to register for SMS and Dialer.

  4. Click ‘Submit’ to complete registration.

**Please note, for Industry, you can choose the Industry that you serve. For example, if you are a tech recruiters, you can select Technology**

You will be able to check the status of your registration application at any time by navigating to the Compliance tab in Admin settings.

You can also cancel the registration process from this view by clicking the ‘Cancel Registration’ button.


What is A2P 10DLC?

A2P 10DLC refers to a system in the United States that allows businesses to send Application-to-Person (A2P) type messaging via standard 10-digit long code (10DLC) phone numbers.

Carriers in the US consider all Twilio traffic to be A2P. Carriers’ A2P 10DLC offerings provide better delivery quality and lower filtering risk than long code SMS of the past, using the same phone numbers.

Why does SourceWhale require me to register for SMS?

These requirements are coming from wireless carriers (AT&T, T-Mobile, Verizon, etc) in order to reduce spam. All applications that allow sending of SMS messages to US numbers require customers to register for A2P 10DLC.

How long will it take for my application to be processed?

A2P Campaign registrations are subject to a manual vetting process by our messaging provider Twilio. For more information on this vetting process, please visit Twilio’s FAQ page.
