<< Learn the benefits of A2P 10DLC

If you would like to send SMS text messages to prospects and clients from a 10-digit local phone number, you must register for A2P 10DLC. If you want to text from a toll-free number, you can continue to do that as you have been.

Registering for A2P 10DLC will be simple!

There are three simple steps to registering for A2P 10DLC within the Trust Center:

  1. Create a business profile for your brand(s) - Now live!

  2. Register your brand(s) for an A2P messaging plan (one time) - Coming soon!

  3. Register your campaigns/use cases (ongoing) - Coming soon!

The Trust Center is live now, and you can register your company by creating a business profile. That will take care of Step 1.

Next is to determine which plan is the right fit for you, and then register for that plan with the required information.

Two Types of A2P 10DLC Plans

After reviewing the patterns of our clients, we believe the majority of our clients will fall under the "Starter" category. But it's important to read through both options so you understand the benefits and limitations of each.

Once you are registered and your campaign use cases are approved, you will be able to connect your existing phone numbers to your A2P profile. There is no need to purchase additional phone numbers to become A2P compliant.


This plan is intended for sole proprietors/free agents and small businesses. It requires only a light registration, and provides simple access to A2P 10DLC for businesses with lower volumes of daily text messages to prospects and customers.

Under the Starter Plan you can have up to 5 phone numbers registered and can send up to 3,000 messages a day per plan, at a rate of 1-2 messages per second (MPS). T-Mobile is limiting Starter Plan users to 1,000 messages a day. Messages exceeding these limits will fail.

There is only one type of campaign under the Starter Plan. The "Starter" campaign is a mixed use campaign type.

It is free to register for the Starter Plan, however the per-message rate will be slightly higher compared to the Standard Plan.


This plan is for businesses with larger volumes of communication. You can have as many phone numbers registered as you like and there are no message limits per day.

Under the Standard Plan, you must announce the use case for your campaign and submit sample messages for approval.

The Standard Plan will require a registration fee (one time) and ongoing campaign registration fees.

Important reminders about A2P 10DLC fees

While additional fees are always difficult to swallow, there are clear benefits to A2P 10DLC. While it may take a while to reach critical mass, the purpose of A2P 10DLC is to weed out spammers and scammers - which will make your legitimate business communications stand out and get noticed.

  • Verified messages will be funneled through separate, priority channels, improving delivery.

  • Verified messages are more likely to be read, trusted, and acted upon by consumers, improving response rates.

  • We are all consumers ourselves, and it will ultimately improve our own quality of life.

These fees are not singular to smrtPhone, but rather will be incurred on any technology platform that is used for business messaging. All VoIP and cloud based phone systems are considered A2P. (Read about other types of messaging besides A2P here).
