10DLC: The new commercialized long code A2P messaging solution

01 Sep 2020 - 6 min read

The growth of A2P text messaging

A lot has happened in the world of messaging over the last few years. The dramatic shift from a phone call to reach a client, to text messaging, has seen many businesses and organizations turn to SMS to reach audiences in ways that, let’s face it, are just more convenient and effective. 

Every day at Sinch, we see new and creative ways to use Application-to-Person (A2P) messaging to connect and engage. But while use cases have grown continuously and evolved, the messaging services that support them have not. That’s all about to change with 10DLC (10-Digit Long Code). 

An update to the CTIA cross-carrier guidelines & carrier-specific messaging playbooks will be released soon to outline further content guidelines for both short codes and 10 digit senders, so watch this space for more information. 

What is 10DLC?

In short, 10DLC are local 10 digit, voice, and MMS capable non-wireless local numbers. We covered more details on this in some previous blog posts, and we also ran a webinarCheck them out for the full story on 10DLC; what they are, why they’re such a hot topic in the US right now, and the difference between toll-free numbers, long codes (or long numbers), dedicated shortcodes, and shared shortcodes. 

We’ll be skipping straight to the nitty-gritty on steps you need to take to start using 10DLC and how Sinch can support you in getting up and running for this blog post. 

What should I expect next with 10DLC?

Wireless carriers will eventually start blocking P2P long codes and shared short code traffic. We expect a grace period after the carriers go live, but our advice is to start preparing for the switch as soon as possible if you are still using shared short codes or running 10 digit SMS over local number.

What steps do I need to take to start using 10DLC?

It’s a simple two-step process: You need to register your brand and then register the campaign you’d like to run. To be clear, one brand can have multiple campaigns, each one can only belong to one brand, but each customer can have multiple brands. All brands and campaigns will be registered on TCR (The Campaign Registry) which is the official 10DLC registry platform. TCR provides the campaign details to the carriers and generates the campaign ID which is needed to route 10DLC traffic. You can bring your numbers or if you don’t have any, Sinch can order and purchase them for you. 

Let’s take a closer look at each step. 

Registering brand information for 10DLC

Brand data consists of information about the company that owns the rights to the brand: the name of the brand, address, and contact details. Sometimes, it’s necessary to provide more specific information, like tax ID and stock symbol. Each brand needs to be approved before they can start sending.

Vetting is required for brand verification purposes. This process uses an external partner and is essential in confirming the brand and intended aggregator ID. Security is key.

When brand registration is complete, the next step is creating a campaign.

Registering campaign information for 10DLC

For every type of A2P messaging planned, brands need to submit their details and get the campaign approved by the carriers.

Carriers require specific information to help with this process, such as the campaign type and use case, an example of the messages planned, whether the message will include a link, and the opt-out options. 

Any new type of A2P messaging requires a new campaign, but there’s plenty of benefits to be gained if you put the work in to get a campaign registered:

  • Brands can host their pool of dedicated numbers (no more snowshoeing/rotation!)
  • Promotional and marketing content will be supported (limited carrier filtering)
  • Based on their trust score, brands can expect much higher throughput per second on each campaign, per carrier
  • 10DLC will support voice and MMS
  • Provisioning will be fast (1-3 days)

It’s important to note that any violations of the submitted and or approved campaign data could result in carriers revoking both the brand and the campaign.
