How to Register Your Business for A2P 10DLC in Calilio?

To register your business for A2P 10DLC in Calilio, open Compliance under Settings, start a customer profile on the Profile tab, and enter your business details and United States or Canadian address. Submit the profile for review, then register your brand on the Brand tab.

Registration runs in three stages, and the stepper at the top of the screen names them: Business Details, Brand Details, and Campaign Details. This article covers the first two, which together register your business. Registering the campaign that carries your messages is a task of its own.

Before you begin

Have your business registration documents to hand. The details you enter have to match them.
You need a United States or Canadian address. A P.O. box is not accepted.
You need a United States or Canadian mobile number you can reply from. A Calilio number cannot be used.

Step 1: Open the A2P Messaging screen

Click Settings, then Compliance under WORKSPACE in the settings menu.
A2P Messaging opens in a new browser tab, on a different address from the rest of the Calilio web app.
The screen opens on the Onboarding tab, which explains what A2P 10DLC covers.

Click Settings, then Compliance to open A2P Messaging.

Step 2: Start your customer profile

Click Profile, the second of the five tabs.
Click Create a Profile at the top right of the table.
The control is unavailable once your workspace has a registered profile, and the table then lists it.

Click Create a Profile on the Profile tab.

Step 3: Answer where you are located

The first step of the profile asks whether you are personally located in the United States or Canada.
Choose Yes or No, then click Continue.
Click Cancel to leave the profile without saving anything.

Answer the location question, then click Continue.

Step 4: Enter your business details

Fill in Legal Business Name, Business Type, Business Registration ID Type, and Business Registration Number.
Choose your Business Industry, add your Website URL, and tick every region under Business Regions of Operation.
Click Save and Continue.

Important: Enter the details exactly as they appear on your registration documents. Calilio states that The Campaign Registry generates a trust score from them, and that a difference in the business name or the address lowers your messaging limits.

Enter your business details, then click Save and Continue.

Step 5: Enter your business address

Choose Enter new address, or pick Select from existing addresses to reuse one already on your account.
Set the Country Code, then fill in Street Address, City, State/Province/Region, and Postal/Zip Code.
Click Save and Continue.

Enter a United States or Canadian address, then click Save and Continue.

Step 6: Review the profile and submit it

Check the contact information and the business address on the review step.
Tick the declaration, which covers identity verification and how long Calilio keeps the profile.
Click Submit for Review.

Tick the declaration, then click Submit for Review.

Expected result

Your profile appears in the table on the Profile tab, with its own Status.
The table shows the business name, the contact name, the country, the business email, and the phone number you registered.
The Brand tab is the next stage.

How do you register your A2P brand?

Open the Brand tab and click Register new Brand. Choose the brand type, enter a Brand Name, pick the Vertical that matches your business, and add a mobile number for verification. Tick the consent line and click Register.

Vertical offers ten industries, from Agriculture through to Healthcare.
Only United States and Canadian mobile numbers are accepted, and a Calilio number cannot be used.
One mobile number can register no more than three Sole Proprietor brands, counting brands registered with other providers.

Fill in the brand form, then click Register.

What happens after you register a brand?

After you register a brand, Calilio sends a verification message to the mobile number you entered. Reply Yes to that message within 24 hours to complete the verification. If the message does not arrive, wait for the countdown on the screen to finish and click Resend verification.

Reply to the verification message, or click Resend verification.

Is there a fee to register an A2P brand?

Yes. Calilio charges a one-time brand registration fee, and the amount is stated twice on the brand step: once above the form and once in the consent line you tick before registering. The plan comparison lists the current charges.

Contact Calilio support

If your profile or your brand stays unapproved, contact our support team with your workspace name, the legal business name you registered, and the date you submitted it.

For your security, do not share passwords or payment card details.
