# A2P Registration Guide

> Register your business for A2P 10DLC texting to send reliable SMS messages to customers.

## What is A2P 10DLC?

A2P (Application-to-Person) 10DLC (10-Digit Long Code) is the industry standard for business text messaging in the United States. US mobile carriers now require all businesses to register their brand and messaging campaigns before sending SMS messages through standard phone numbers.

Without registration, your text messages may be filtered, throttled, or blocked entirely by carriers.

## Why Do I Need It?

* **Reliable delivery** — Registered messages are trusted by carriers and reach customers consistently
* **Higher throughput** — Send more messages per second compared to unregistered numbers
* **Carrier compliance** — Meet regulatory requirements from T-Mobile, AT\&T, Verizon, and other US carriers
* **Avoid filtering** — Unregistered messages are increasingly blocked as spam

## Registration Fees

| Fee                   | Amount | Frequency |
| --------------------- | ------ | --------- |
| Brand registration    | \$4    | One-time  |
| Campaign registration | \$15   | One-time  |

These fees are covered by your Answering Agent plan — there is no additional cost to you.

**Opt-out requirements:**

If you collect personal information through text messaging, you should have a privacy policy that covers:

* How customers can opt out
* How you protect customer information

## After Approval

Once your registration is approved:

1. **Status updates** — Your texting settings page will show "Approved" status
2. **Select a sender** — Choose a default phone number for outbound texts
3. **Start texting** — Your AI assistant can now send text messages to callers
