Why 10DLC regulation?

10DLC is the new industry-led long-code solution to increase consumer trust and messaging volume and reduce spam texts for A2P (Application-To-Person) business messaging. It allows businesses to send sanctioned A2P messaging traffic over phone numbers. 

When businesses text over long codes, the carriers need a solution that protects consumers from messaging spam. The U.S. carriers will now offer the same to encourage the growth of businesses communicating with their consumers through text messages while also protecting the consumers from unwanted messages. The 10DLC registration ensures that end users receive text messages that are verified and valid and allows legitimate businesses to send a large volume of messages.

The idea of the 10DLC regulation is you must own and declare the messages 💬 you send. And help mobile carriers know that you do not spam consumers. It is a step in the right direction to prevent spam and increase accountability in the entire messaging ecosystem.

What is 10DLC?

10 DLC is a 10-digit phone number (for example 555-555-5555) that businesses use for promotional and transactional texting.

What is the 10DLC regulation?

It is the new anti-spam regulation brought by the U.S. wireless carriers and industry groups in collaboration with the Federal Communications Commission (FCC) and the Mobile Marketing Association (MMA). It applies to all businesses using applications (such as SMS-Magic) to send text messages over long codes in the United States. Under this regulation, businesses have to register their long codes with The Campaign Registry (TCR).

What is The Campaign Registry (TCR)?

TCR  or The Campaign Registry is the reputation authority for business messaging on 10DLC. The 10DLC (10-digit long code) Campaign Registry is a database that keeps track of various 10DLC text messaging campaigns. It records information about these campaigns, including sender information, campaign content, opt-in and opt-out management, and compliance with regulations and guidelines. The registry helps ensure proper oversight and management of text messaging campaigns using 10DLC numbers, promoting transparency, and compliance with industry standards.

To whom does the 10DLC regulation apply?

It applies to all businesses using applications (such as SMS-Magic) to send text messages over long codes in the United States. Under this regulation, businesses have to register their long codes with The Campaign Registry (TCR) – the reputation authority for business messaging on 10DLC.

What is A2P texting?

A2P stands for Application-to-Person. And A2P texting refers to the practice of sending text messages from an application or software system to individuals. It involves automated or programmatic communication where businesses, organizations, or service providers send text messages to their customers or users.

A2P texting is widely used for various purposes, such as:

  • Notifications: Sending alerts, reminders, or notifications to customers about important updates, appointments, or events.
  • Marketing and Promotions: Conducting marketing campaigns by sending promotional offers, discounts, or announcements to a targeted audience.
  • Authentication and Verification: Sending verification codes, one-time passwords (OTPs), or account activation links to verify user identities during registration or login processes.
  • Customer Support: Engaging in two-way communication with customers for support queries, order status updates, or resolving issues through text-based interactions.
  • Surveys and Feedback: Collecting customer feedback or conducting surveys by sending text messages with questionnaires or links to online surveys.

A2P texting is commonly used by businesses in industries such as higher education, finance, healthcare, lifestyle and wellness, law services, staffing and recruitment, and contact centers. It provides a convenient and effective way to reach a large number of individuals quickly and reliably. However, it’s important for businesses to comply with local regulations and guidelines to ensure user privacy, prevent spam, and maintain the trust of their customers.

What is A2P 10DLC?

A2P 10DLC is a system in the U.S. that enables businesses to send A2P messages via 10-digit long code phone numbers. A2P 10DLC is specific to long-code messaging and does not affect short-code numbers messaging or toll-free numbers.

Consequences of not registering

Businesses that do not register for 10DLC by May 31, 2023, could face messaging disruption starting June 1, 2023. Increased message filtering and fees will apply to messages sent without registration. Soon, unregistered messaging to the US via long code numbers will start getting blocked altogether. This could directly affect the performance of all their customer-facing communications and functions.

Surcharges for unregistered 10DLC messaging

Please be advised that the following 10DLC pass-through surcharge fees will increase for T-Mobile and AT&T. We expect to see similar trends with other carriers so kindly register for 10 DLC campaigns to avoid carrier surcharges. With this increase in surcharge fees, the per-text messaging cost will increase drastically for the unregistered numbers.  


Unregistered and/or Non-Migrated traffic will be charged at the pass-through rate and effective dates indicated below.

Please complete 10DLC registration to avoid increased pass-through fees. Please keep in mind that the carriers can enforce a zero-tolerance policy at any time

The sending of Unregistered and/or Non-Migrated traffic is a violation of the Participating Carrier Requirements and as such, the 10DLC delivery hub reserves the right to potentially suspend, terminate or block messages or non-sanctioned traffic as required to maintain compliance with Participating Carrier Requirements.

Benefits of 10DLC registration

  • Higher messaging volume: With 10DLC registered numbers you can send higher volume messages at a much lower cost than shortcodes
  • The common number for voice and text: 10DLC numbers are text as well as voice-enabled so you can receive texts on the same number that customers call you on.
  • Goodwill among mobile carriers: Having 10DLC registration also improves your goodwill among carriers and communication providers. It prevents unintentional spam filtering, so you enjoy higher deliverability than unregistered long codes.

10DLC numbers give businesses the best of both worlds: mass text messaging support with lower overhead costs. This is what you can expect from 10DLC:

Higher SMS Message VolumesA 10DLC number is much more capable of A2P text messaging than a local long code
Lower CostThe 10DLCs operate relatively low in cost compared to shortcodes. So, businesses that can’t afford a short code number or don’t send enough messages to justify paying for a short code have a cost-efficient alternative. Businesses can send more messages from their existing phone number and won’t have to pay for an additional number to get 10DLC capabilities.
Support & AssuranceThe communications providers will look over businesses and the 10DLC messaging programs before allowing them to send A2P messages. This will assess the risk, ensure proper usage, and avoid unintentional spam filtering
Carriers, Carriers’ customers, and BusinessesThe 10DLC brings many benefits to carriers, carriers’ customers, and businesses. Carriers protect their consumers from unwanted and nuisance messaging spam. Businesses gain higher throughput than they could with the unregistered long codes and have a more affordable alternative to short codes and toll-free numbers. End users get increased confidence and trust in their No. 1 means of communicating with businesses.
Text and Voice-enabled phone numbersThe 10DLC numbers also support voice and allow the customers to send or receive text messages on the same number they call you from. This creates a more seamless customer experience and makes engaging with your business easier and more convenient with calls and text messages.
Local phone number recognitionThe 10DLC helps businesses confidently to send text messages to customers individually or at a large scale with a local phone number. It improves customer engagement and experience.
Better DeliverabilityThe term vendors sanction 10DLC numbers, and messages sent on these numbers are more likely to reach the recipient than with regular local long codes.

How can you register for 10DLC and what time it takes?

The U.S. mobile carriers require all businesses sending A2P messages on a 10DLC phone number to register their brand and campaign with a chosen campaign service provider (for example SMS-Magic).

Once we submit your brand and campaign details on TCR (The Campaign Registry) portal, the TCR authorities verify your application. After successful verification, TCR grants you 10DLC registration. This is a multi-step process as below:

  • Step 1: Register the brand and legal identity of your business or organization
  • Step 2: Register your campaigns (various transactional and promotional messages you send over long codes)
    • Optional step: Additional vetting
  • Step 3: Map your long codes (10-digit phone numbers) to registered campaigns.
  • Business as usual: Continued compliance.

The time it takes to register for 10DLC

Brand registration (step 1) ideally 5-10 minutes with a flawless EIN (Employer Identity Number) match. If there is any discrepancy, then resolving that can take up to a week of coordination and resubmission.
Similarly, campaign registration (step 2) typically takes 1-3 days if all goes well. If rejected, then resolving the same can take anywhere up to 3 weeks of coordination and resubmission.

What does brand registration (step 1) for 10DLC mean?

The Campaign Registry asks businesses sending A2P messages over long codes to own and undertake responsibility for the messages they send. Thus it requires every brand to declare its legal identity and company registration details. This is step 1 in 10DLC registration. Only after successful registration of the brand, can you register your campaigns (messages you want to send over 10-digit long codes). 

What does campaign registration (step 2)  for 10DLC mean?

The Campaign Registry asks businesses sending A2P messages over long codes to show that the messages they send are not spam. Thus it requires every brand to declare the various types of transactional and promotional messages it sends. They call it the submission of ‘campaign use cases’. Brands have to register each campaign use case separately. With each use case, the brand has to also submit the sample message content and opt-in, opt-out, and support details. This is step 2 in 10DLC registration. Only after successful registration of the brand, can you register your campaigns (messages you want to send over 10-digit long codes).

Shortcode is a 4 to 6-digit number used by businesses for global non-consumer (A2P) messaging. These are ideal for Enterprise level, large-scale, unlimited customer bases and are generally used for marketing blasts, one-time passwords, fraud alerts, and more. Ex.: 156762

10DLC – is the industry-led long code solution for non-consumer (A2P) messaging. These are ideal for localized, in-branch or in-store, smaller, segmented customer bases and are used for chat (text and voice), event-based interactions, service updates, and appointment reminders. Ex.: +1 415 123 2678

A toll-free number (8XX), which has been text-enabled, was available for voice calls. These are ideal for enterprise-level or localized, large-scale or in-branch, low messaging volumes, and used for customer service chat (text and voice) customer feedback, notifications, and updates. Ex.: 1 (800) 227-4567.
