A2P 10DLC for Insurance Agents — What You Need to Know

What is A2P 10DLC?

A2P stands for Application-to-Person. 10DLC stands for 10-Digit Long Code — a regular phone number that looks like any other 10-digit number but is registered with mobile carriers for business messaging.

Since 2021, the major US carriers (AT&T, T-Mobile, Verizon) have required businesses sending SMS at scale to register their brand and messaging use case. This registration process is called A2P 10DLC.

Why does this matter for insurance agents?

Without proper A2P registration, your SMS messages to leads and clients may be:

• Filtered — silently blocked by carriers so they never reach the recipient
• Delayed — held for review before delivery
• Flagged as spam — marked with a spam warning on the recipient's phone

If you are wondering why your SMS follow-up campaigns have poor response rates, A2P filtering may be the reason.

How A2P registration works

The process has three steps:

1. Brand registration — Register your company with TCR (The Campaign Registry). Provide your EIN, company name, and business type. This is a one-time step.

2. Campaign registration — Describe how you will use SMS. For insurance agents: "Licensed insurance agent sending appointment reminders, quote follow-ups, and policy status updates to opted-in clients."

3. Phone number assignment — Assign your 10-digit phone number to your approved campaign.

The problem with self-managed A2P

Most CRM providers give you a phone number and tell you to handle A2P registration yourself. The registration portal is technical, the use-case descriptions require specific wording for insurance, and approval can take weeks. Agents who fill this out incorrectly end up with filtered messages or rejected campaigns.

How SonicCRM handles A2P

SonicCRM is registered as a platform-level brand with TCR. Every SonicCRM customer gets a phone number that is already assigned to an approved insurance-specific campaign. You do not fill out any forms, wait for any approvals, or manage any registration.

You sign up, you get a number, your SMS delivers.

This is a significant difference from platforms where A2P is your problem. For insurance agents sending high volumes of lead follow-up and client communication, reliable SMS delivery is not optional.

TCPA compliance for insurance SMS

Beyond A2P registration, insurance agents must also comply with the Telephone Consumer Protection Act (TCPA):

• Get written consent before sending marketing SMS
• Include opt-out instructions in every message (STOP)
• Honor opt-out requests immediately
• Keep a record of consent

SonicCRM's SMS module includes built-in opt-in tracking, automatic opt-out processing, and STOP keyword handling. Your opt-out list is maintained automatically so you never accidentally message someone who has unsubscribed.
