Register for A2P 10DLC texting (US)

In the US, phone carriers require every business that texts customers to register first. This is called A2P 10DLC registration. Without it, carriers may block or filter your texts.

Registration has three steps: your brand (your business), your campaign (what kind of texts you send), and assigning your phone numbers.

Before you start

Have these ready:

• Your legal business name and EIN (tax ID), exactly as they appear on your IRS paperwork.

• Your business address, website, email and phone.

• A contact person's name, email, phone and job title.

• A link to your privacy policy and terms & conditions pages.

• Two sample texts you plan to send.

Open the registration

1. Click Settings, then Integrations.

2. Click Configure Telephony.

3. Open the Compliance tab and find A2P 10DLC Registration.

Step 1: Register Your Brand

1. Click Pre-fill from Business Details to fill in what you already entered.

2. Check the Business Name, EIN / Tax ID, Business Type, Industry and address.

3. Fill in the contact person's details.

4. Click Register Brand.

Step 2: Register Your Campaign

1. Choose a Use Case, such as Customer Care, Marketing or Mixed.

2. Choose your Opt-in Method: how customers agree to get your texts.

3. Write a Description of the texts you send.

4. Add Sample Message 1 and Sample Message 2. Include your business name and "Reply STOP to opt out."

Common reasons for rejection

• The business name or EIN doesn't exactly match IRS records.

• The website is missing, under construction, or has no privacy policy.

• Sample messages don't match the use case, or don't include opt-out wording.

Troubleshooting

• "No SMS-capable number on this sub-account yet." Buy a phone number first.

• You see a message that a phone connection is required. Your phone service isn't set up yet. Submit a ticket and we'll help.
