Overview: Update Aug 12, 2021:

All Aloware customers must now provide their brand registration information for 10DLC and A2P messaging, under Account > Compliance (link). Unregistered brands might be subject to 100% SMS filtration and undeliverability as of October 1, 2021.

What is A2P 10DLC?

A2P 10DLC stands for “Application-to-Peer Ten-Digit Long Codes”. A Ten-Digit Long Code (10DLC) is simply a phone number and area code (e.g. 555-555-5555), excluding Toll-free numbers.

10DLCs have always existed, but beginning in 2021, US carriers have decided to treat SMS traffic from Application-to-Peer (A2P) services differently.

Sending a text from one mobile handset to another is referred to as P2P (Peer-to-Peer), whereas sending a text via software like Aloware is considered A2P.

Under this framework, users of these lines will now need to formally declare their intention with wireless carriers in order to conduct commercial texting under A2P 10DLC.

Why is A2P 10DLC Happening?

US carriers are using A2P 10DLC to separate commercial and P2P use cases in order to provide a better experience for their wireless subscribers.

The goal is to increase transparency and reduce SMS & MMS spam from local numbers. Text messaging deliverability and volume will ideally improve for compliant texters overall while noncompliant texters will face increased costs [e.g. unauthorized bulk SMS, spam SMS].

Telecommunications networks implement A2P 10DLC — not the FCC.

Who will be affected by A2P 10DLC?

This change affects everyone who texts in the United States using Ten-Digit Long Codes via A2P services like Aloware. This change is not unique to our product and is being implemented across the industry.

However, if your organization sends fewer than 3,000 per day, you will still need to register basic information about your brand under A2P 10DLC; however, the impact of the framework will likely be negligible.

Note: Text traffic over Toll-Free numbers is not subject to A2P 10DLC requirements.

Toll-Free numbers are already sanctioned for business use, and their text traffic will not be subject to filtering or tariffs in the same manner as A2P 10DLC traffic.

A2P 10DLC Compliance in Aloware Overview

Under A2P 10DLC, commercial texters will need to register information about their business, use cases, and specific campaigns directly with U.S. telco networks.

Aloware will be gathering the necessary information from our clients in order to manage the registration process. Once registered, the networks will determine the volume and level of filtering for texting campaigns based on an assigned Trust Score.

Daily message limits based on Trust Score are shown below:

Trust Score

T-mobile message limit (SMS Segments + MMS) outbound









For Starter brands, a limit of 1,000 SMS and MMS segments per day is applied.

How do I make sure my Aloware lines are A2P 10DLC compliant?

For each line you want to preserve SMS Capability:

  • Go to the Line's Settings (Line > Settings)

  • Submit the A2P 10DLC form (you'll need to register your brand first). Follow the instructions here before proceeding.

  • Take note that A2P 10DLC registration incurs cost.

How do I create a Caller ID for each line?

  • Go to the Line's Settings (Line > Settings)

  • Submit the Caller ID name you'd like to be associated with the line

How will you know the status of each line's A2P 10DLC Registration?

Each Line's Settings section will display the status of your A2P 10DLC registration as:

  • Successful A2P 10 DLC Campaign Registration

  • Unregistered A2P 10DLC Campaign

  • Pending Review A2P 100DLC Campaign

    This may take up to 48 hours to process

How will A2P 10DLC impact the cost of texting?

Aloware will not change in response to A2P 10DLC; however, the carriers will levy additional pass-through fees on text traffic from our customers that reach their subscribers. This fee will be passed on to our clients with no markup. You can read more about the fees in this article:

Carrier Fees for AT&T, Verizon, and T-Mobile

Because each network has a different rubric for its specific A2P 10DLC pass-through fees, the networks have not been consistent. If you require additional carrier information, please consult this guide from our vendor, Twilio.

When does A2P 10DLC go into full effect?

As of May 2021, only a few U.S. carriers have provided a confident timeline for full A2P 10DLC implementation.

This is the best resource for carrier-specific updates.

Because each carrier has different timelines and methods of enforcement, Aloware strongly encourages organizations to register as soon as possible in order to avoid any surprise fees or filtering.

Existing Aloware customers MUST provide their registration information under Account > Compliance (link).
