10DLC brings major changes to the way businesses use SMS
Recently, the major American cell phone carriers launched a new sales model for SMS called 10-digit long code (10DLC). This new model is intended for businesses that use application-to-person (A2P) SMS communication. For Plum Voice, this means all our customers that use local numbers for SMS.
The goal of this page is to:
- 1.Explain what 10DLC is
- 2.Address how 10DLC impacts Plum Voice customers
- 3.Explain the 10DLC registration process
- 4.Provide a timeline for 10DLC implementation
What is 10DLC?
Background
Mobile carriers designed 10DLC to enable businesses to send bulk SMS using local phone numbers. Under 10DLC, carriers will not allow unregistered 10-digit local phone numbers to send bulk A2P messaging. Businesses must use other number types for bulk messaging, such as short codes and toll free numbers, or register their 10-digit numbers under 10DLC. 10DLC provides a way for businesses to use local numbers with higher throughput (the number of messages per second) and deliverability.

As a new initiative, there remains many unknowns about 10DLC and the processes around it. Plum Voice is working with carriers to clarify expectations and requirements related to 10DLC. We will pass along important information to you when we have it.
We appreciate your cooperation with the registration process and your patience with the transition. We will continue to refine our procedures and processes related to 10DLC to ensure minimal impact on our customers.
Toll-free SMS numbers are not subject to 10DLC registration requirements, but they have their own separate registration requirements.
10DLC Registration
One key aspect of 10DLC is the need to register companies and their SMS use cases. The registration process and fees associated with 10DLC are, in part, designed as a roadblock for SMS spammers.
​ Once carriers begin to enforce 10DLC compliance, unregistered SMS traffic may be subject to new, and increased levels of filtering, blocking, or fines.

How do you register for 10DLC?
The short answer: You don’t.
Plum handles the registration process for you. You simply need to provide the necessary information to Plum.
The long answer: The carriers have set up a registration process called The Campaign Registry. You can read The Campaign Registry FAQs here.The two key entities for registration purposes are Brands and Campaign Service Providers (CSPs). In this model, you, a Plum Voice customer leveraging Plum’s platform to automate SMS, are considered a Brand. Plum Voice is considered a CSP.Plum Voice, is responsible for providing The Campaign Registry with accurate Brand information.
​ To reiterate, at this time you SHOULD NOT register your company directly with The Campaign Registry. Plum Voice will handle 10DLC registration.

For each Brand (i.e., business) we need the following information:
- Legal company name
- Physical address
- Country of registration
- Employer ID Number (EIN) / Tax ID
- Type of company (public/private/charity or NPO)
- Website address
- Vertical (See list)
- Stock symbol (Public company only)

Brands can choose from the following list of verticals. Select the one that most closely resembles your business.
- Agriculture
- Communication and Mass Media
- Construction and Materials
- Education
- Energy and Utilities
- Entertainment
- Financial
- Gambling/Lottery
- Government
- Healthcare
- Hospitality and Travel
- Information Technology
- Insurance

In addition to Brand information, you need to include details about each campaign (i.e., use case) you plan to run.
- Campaign Type
- Phone number(s) for that campaign
- Sample message that the campaign will send
- Campaign lifecycle (open-ended vs start/end dates)
For example, if you use SMS for two-factor authentication (2FA) and account notifications, those should be set up as two separate campaigns.
Each SMS-enabled phone number can be associated with only one campaign type.
