A2P Registration

Some countries require legal documentation before a number can be activated. These are industry regulations, not something Ivorey controls, and are handled via third-party review.

If you want to register phone services in the United States through Ivorey, then A2P 10DLC registration is a legal requirement. A2P means "Application-to-Person" and 10DLC is your 10-Digit Long Code (your standard business phone number).

You'll need to purchase and complete A2P registration, which verifies your business as a legitimate sender for SMS and helps you to stay compliant and avoid being flagged as spam.​

After you register, your brand gets a Trust Score. It tells carriers how trustworthy your brand is. Higher scores = higher message throughput (faster and more reliable sending).

Your Trust Score is based on:

• Whether your info matches across your website, brand name, and messages

• How transparent you are about opt-in and opt-out

• Your messaging history

1. From the Ivorey main menu, go to [Settings] > [Phone Services] > [Trust Center] > and under A2P Messaging, click the [Start Registration] button​

   1. If your business has a Tax Number (EIN for the US, CCN for Canada, etc.), please select [Yes, the business I’m registering has a US EIN] (Standard Low Volume Brand Registration)​

   2. If your business does not have a Tax Number but operates from a valid Business Address in the US/Canada, please select [No, the business I’m registering does not have a US EIN] (Sole Prop Brand Registration)​

   3. If your business does not have a Tax Number and the business address is not in US/Canada, unfortunately you cannot proceed with A2P Brand Registration. In this case, the best alternative would be to use Toll-Free numbers​

      2. Click the X or [Back] button, to address the issues and proceed
         ​

   Note: While this compliance review is designed to reduce common causes of rejection, the feedback and suggestions provided do not guarantee carrier approval.​

9. When you're ready, click [Submit]​

After you hit Submit on your A2P Brand registration application:

• Your application goes for third party approval. This process can take up to 2 weeks, but is usually quicker. Please note that Ivorey has zero control over this process and we cannot do anything to speed it up. ​

• If denied, you'll need to address any errors and resubmit. ​

• Once your Brand registration is successfully approved as part of the A2P 10DLC setup, the next essential step is to register a Campaign associated with that Brand. This step is mandatory to begin sending A2P messages through 10DLC phone numbers. It’s very important to note that Campaign registration is not triggered automatically once your Brand gets approved.​

• You will need to manually submit the Campaign registration yourself, after Brand approval. Until this is done, your A2P 10DLC setup remains incomplete, which means you will not be able to send compliant SMS messages through your 10DLC numbers.

1. From the Ivorey main menu, go to [Settings] > [Phone Services] > [Trust Center] > and under A2P Messaging, click the [Create Campaign] button​

2. Follow the prompts to complete the Campaign registration form​

3. Await Campaign approval before using your number for A2P messaging

Sole Proprietor is for individuals without an EIN. Standard Brand is for registered U.S. businesses with an EIN.

Likely reasons for an A2P rejection include EIN mismatch, invalid website, or use of a PO Box address. Ensure the legal business name and EIN number match exactly to what’s shown on the CP 575 form. Do not use the business name found on W2 or W9 forms, as they may differ. If the business name spans multiple lines on your CP 575/147c letter, you must enter all lines above the address line during registration.

• Example:
  ABC Holding Group Inc.
  Division of Regional Services
  123 Main Street
  New York, NY 10001
  ​
  The legal name to enter would be: ABC Holding Group Inc. Division of Regional Services

Yes, after your brand and campaign are approved, you can add new numbers which will be automatically registered under the same campaign. There is no resubmission is needed, but it may take several days for registration to complete.

If your A2P 10DLC registration fails multiple times, it may reach the maximum retry limit. When this happens, the A2P section in the Trust Centre appears greyed out and the registration wizard is no longer available.

Once the retry limit is reached, the registration can’t be resubmitted from your end, even if you’re prompted to do so. An internal reset is required before you can return to the Trust Centre and submit the registration again. Please reach out to Support via the live chat widget to request a reset.
