What is 10DLC, and What Does It Mean to SMS Messaging?

A 10DLC number is essentially a local 10-digit phone number that enables your business to send high volumes of text messages. 10DLC numbers give you an optimal mix: mass text messaging support and lower overhead costs.

How does 10DLC work in practice, and what do you need to do?

You can use a Campaign Service Provider like Clickatell. Once the provider gathers your information, they submit a request to the regulator on your behalf. As soon as your brand and campaign has been approved, you can start using the 10DLC number to send mass notifications or marketing campaigns.

A 10DLC number is a perfect way to ensure that your messages reach their intended recipients on time.

Why 10DLC?

In the past, companies have used shared short codes for text messaging campaigns, which are a high spam risk according to the carrier networks. Shared short codes represent a very difficult-to-manage communications platform for businesses. Businesses risk broadcasting disruptive messages or having the short code shut down when other carriers see a single message they deem inappropriate. Likely this will affect all business users on the channel negatively. AT&T and T-Mobile have now prohibited the use of shared short codes and require companies to either register for a dedicated short code or 10DLC number for A2P (application-to-person) messaging.

The benefits of using the 10DLC system

10DLC has many benefits for businesses looking to increase their mobile marketing efforts. Customers can identify the messages they receive from companies, and you can save money by sending more texts without worrying about text charges or delays in delivery time.

Benefits include:

  • Mass texting

  • Higher throughput

  • Reliable delivery

  • Reduced costs

  • Voice support

  • A new stream of revenue

  • Increased customer engagement

  • Better customer experience


Who should use this system?
  • Companies looking for a more cost-effective way to send SMS marketing messages.

  • Companies that need to send many texts, but don't want to encounter blocks because of their texts being labeled as spam.

  • Companies that want to provide a better user experience by creating text flows that lead to the customer's desired outcome.

  • Companies that would like to take advantage of the higher open rates that SMS messages receive versus traditional email campaigns.

What kind of information do I give Clickatell to register?

If you want to send and receive long numbers through the U.S., you need an A2P 10DLC number.

Register by providing us with your business's:

  • Legal company name

  • Country of registration

  • Type of organization (i.e., nonprofit)

  • Tax ID or EIN

How long is the registration process?

As of February 1st, there is a mandatory vetting process to confirm your campaign is compliant with best practice. The current indication is that this process will take 5 days although this is subject to change. Once the carrier has reviewed and given good standing to your campaigns, you can use the 10DLC. Please note that Mobile Network Operators can reject or suspend a campaign if it doesn’t comply with the guidelines for that campaign, resulting in the linked 10-digit long numbers being blocked.
