A2P 10DLC Registration with Carrier

After activating your Smarter Contact account, you need to register your Brand and Campaign due to A2P 10DLC.

Mobile carriers are requiring all US businesses sending SMS through the A2P 10DLC system to register with them.

With Smarter Contact, you can register for FREE.

We kept it as SIMPLE and SMOOTH as possible.

Here’s how you can get registered and start running your campaigns.


1. Activate your subscription on the Membership page.

2. Go to the A2P 10DLC page in the Settings of your account.

3. Add the required info to the relevant fields:

Describe Campaign

• Message flow: Describe how a customer opts into a campaign, thereby giving consent to the sender to send messages. If a campaign supports different opt-in mechanisms, you must mention all of them.
e.g. Our company has a website where contacts submit the form, providing their contact details and consent to receive messages from us. We collect this data and use it to send our campaigns. (NOT TO BE USED IN REAL FORM)

• Describe your SMS campaign
• Campaign Alias/Title

• Sample Message 1: The message should have opt-out language Reply STOP to unsubscribe.
• Sample Message 2: The message should have opt-out language Reply STOP to unsubscribe.

4. Once you’ve added all the necessary information, click Submit.

5. Wait for the registration to get approved.
After the Brand registration approval, you can purchase owned numbers to get them approved by the carrier.


  • All form fields are required for submission
  • You can have up to 49 numbers in your account with Standard A2P 10DLC registration
  • The average approval time is around 72h. Registration for brands with new EIN may take longer, as it takes time for IRS to update the national registry.
  • The approval of your registration is done on the carrier’s side, and we cannot speed up the process.
  • Carriers may also ask you to submit copies of the documents to prove the brand ownership.
  • You also need to register your subaccounts. Message templates should be different for each account, while message flow, campaign description, and campaign title can be similar to the data submitted for the main account.
    Each subaccount can also have 49 owned numbers.
  • Trial users can’t register with A2P 10DLC. Activate your subscription to register
