Self-Serve Registration Process for A2P 10DLC

I’m ready to register for A2P! Is it a self-serve process?

The first question to ask is: do you anticipate sending more than 5,000 message segments in any given day within your Avochato inbox?

  • If the answer is “No, I won’t send more than 5,000 message segments in any given day,” then the process is fully self-serve and you can complete the 3 steps below on your own. Avochato will automatically register your business and will allow you to create a low-volume use case for each inbox. If you have only one Avochato inbox (also known as a phone line), then you only need to create one low-volume use case. If you have multiple, you will need one per inbox.
  • If the answer is “Yes, I will send more than 5,000 message segments in any given day” then please only complete Step 1: Business Registration, have a look at the Standard and Special Use Cases listed here, and contact us at 415-214-8977 or We will help get your account set up with a high-volume use case to ensure higher throughput and deliverability. If you have multiple inboxes, and some are expected to be high volume but others are not, you can complete steps 1 through 3 below for the low-volume use case inbox(es), and we will help set up the high-volume ones.

How can I verify my business for A2P?

Avochato has made it easy for you to register to A2P in just 3 steps:

  1. Business Registration
  1. Use Case Creation
  1. Syncing Use Case to an Inbox

In order to be verified successfully, you need to complete all 3 steps.


To start, navigate to Settings from the left-hand menu. At the top, you will see a NEW section called "Verify Business" — click on A2P & Use Case. This will take you to the “Verify Business” page.

  1. Business Registration
      • Click on the "Register for A2P" button to fill out the form. If this button is greyed out, it means your account is still in trial mode. Make sure you have upgraded your account before applying for A2P 10DLC.

      • Important: Please ensure your data is accurate. EIN must exactly match your business name and your business address on file with your state / government registration. Providing inaccurate business information will cause carriers to reject the application, leading to additional $4 fees for each subsequent submission. Please make sure your business type, EIN, business address, and other business details are accurate before submitting your application to avoid any duplicate $4 charges from carriers.

      • Note: A Use Case helps carriers know the types of messages you will be sending to your contacts. Carriers ask you to provide two sample messages as well as a description of the type of communication you will be sending to recipients. Be as specific as possible to avoid a rejected application. Make sure you include in each sample message:
        • Your business name when introducing yourself to a contact
        • Appropriate opt-out language such as “Reply STOP to opt out”

      • Important: A Use Case can only be tied to one inbox, so you will need to add as many Use Cases as you have inboxes.
  1. Syncing Use Case to an Inbox
      • Once a Use Case is submitted, an 'Account' column will appear with a drop-down menu. Within the drop-down menu, select the specific inbox that the newly submitted Use Case will be assigned to. Repeat this step if you have multiple Use Cases.
      • This is an important last step to ensure your account is fully verified on A2P.
