A2P Texting Registration

US carriers require businesses to register before they text customers from a local 10-digit number. The A2P messaging registration page is where you submit your business and campaign details once, then follow the status until your local numbers are approved to text.

Why registration is needed

A2P (application-to-person) 10DLC is the US carrier system for business text messages sent from standard 10-digit local numbers. Carriers filter or block texts from local numbers that aren’t registered, so each business registers its brand (who is sending) and its campaign (what kind of messages it sends and how people agree to receive them). One registration covers all the local numbers in your workspace.

Where to find it

Open Phone Numbers from the sidebar. If your workspace owns at least one local number, a card called Register local numbers for SMS (A2P) appears; click Register to open the A2P messaging registration page. You can also click View messaging approvals & readiness on the same screen and open the Local numbers (A2P) tab, which shows the same form. New to numbers? Start with Phone Numbers.

What you submit

The form is split into three sections:

• Business (Brand) — legal business name, business type (sole proprietor, partnership, LLC, corporation, non-profit, or government), EIN / tax ID, country of registration, industry, business website, street address, business email, and business phone.
• Primary contact — first and last name, email, phone, and job title of the person responsible for the registration.
• Campaign & messaging — the campaign use case, estimated monthly messages, a description of how you’ll use messaging, one to five sample messages (one per line), how people consent to receive your messages, whether messages may contain links or phone numbers, and anything else you want to add.

The legal business name, business type, EIN / tax ID, business website, business email, contact email, use case, campaign description, consent description, and at least one sample message are required. If one is missing, the page tells you which field to fill in.

How to submit your registration

1. 1
   Fill in Business (Brand) with your legal details, exactly as they appear on your official business and tax records.
2. 2
   Add the Primary contact for the registration.
3. 3
   In Campaign & messaging, pick the use case that matches most of your texts and write sample messages that look like the texts you will really send, such as appointment confirmations or follow-ups after a call.
4. 4
   Explain clearly how customers agree to receive texts from you, for example by giving their number when they book.
5. 5
   Check Numbers this covers in the right-hand panel to see which local numbers the registration applies to.
6. 6
   Click the submit button at the bottom of the right-hand panel. If a registration fee applies to your workspace, the button and a note above it show the amount before you submit.

Registration statuses

The banner at the top of the page shows the current status next to a four-step progress bar: Details, Submitted, In review, and Approved.

• Not registered — nothing has been submitted yet.
• Pending review — your details are saved and waiting to be processed. You can still change them and click Update submission.
• In review — your registration is with the carriers. The form is locked; contact support if something must change.
• Approved — your local numbers are cleared to send texts. The form stays locked; contact support if you need changes.
• Rejected — the banner shows the reason. Correct the details it mentions and submit again.

What happens while it’s pending

Until your registration is approved, your local numbers can’t be used to send texts. The Readiness tab of Messaging approvals & readiness shows what your workspace can send today: the Outbound SMS sender currently in use, such as the shared platform number, and a What is gated right now list of everything still waiting on approval.

On the shared platform number, texts are outbound-only, so Two-way SMS threads stay off until you send from your own approved number. Phone calls aren’t affected: your numbers keep answering calls with your AI agent while the registration is reviewed.

Tips for a smooth review

• Make sure the legal name, EIN, and address match your official registration records exactly.
• Enter a working website address for the business.
• Keep sample messages realistic and include your business name in them.
• Tick Messages may contain links or Messages may contain phone numbers if your texts will include them.

Frequently asked questions

Do I need A2P registration for toll-free numbers?

No. A2P covers local 10-digit numbers only. Toll-free numbers use their own verification on the Toll-free tab of Messaging approvals & readiness.

Do I register each local number separately?

No. One registration per workspace covers the local numbers listed under Numbers this covers.

Can I change my details after submitting?

Yes, while the status is Pending review: edit the form and click Update submission. Once it moves to In review or Approved, the form is locked and you need to contact support.

What if my registration is rejected?

The reason appears under the Rejected status. Fix the details it points to and submit the form again.

Is there a fee to register?

If a fee applies to your workspace, the amount is shown on the submit button and in a note above it before you submit, so you always see it first.
