While the experience for your customers won’t change much, the process of sending text messages will be a bit different for your business. Here’s what you need to know:

What is 10DLC?

10DLC stands for 10-Digit Long Code, which refers to a standard 10-digit phone number that businesses can use to send text messages to their customers. This system is designed specifically for Application-to-Person (A2P) messaging. This means businesses can use these numbers to send bulk messages more effectively while still maintaining the personal touch of a local number.

Why Should Your Business Use 10DLC?

10DLC offers several benefits that can help your business improve its SMS strategy:

Carrier Support and Protection Against Spam:
Like short codes, 10DLC numbers are vetted by mobile carriers to ensure they are being used properly. This process helps reduce the chances of your messages being flagged as spam. Each carrier may have its own guidelines and fees, so it’s important to understand the rules before starting.

Local Number Recognition:
Customers are more likely to engage with a message from a number they recognize. 10DLC lets you send text messages from a local number, helping you build trust and improve engagement. Whether you’re running a local delivery service, grocery pickup, or a neighborhood salon, a local number makes communication feel more personal.

Voice and Text on the Same Number:
10DLC numbers support both texting and calling. Customers can reach you via text or phone using the same number. This makes it easier for them to connect with your business in whichever way is most convenient for them.

Why is Registration Required?

Mobile carriers are now requiring businesses to register their 10DLC numbers and SMS campaigns. This registration process is not optional. It’s a rule set by the carriers to reduce spam and ensure that only legitimate businesses can send SMS messages. If your business wants to continue using SMS, you’ll need to register or face potential fines.

What If You Don’t Want SMS Services Anymore?

If you decide you no longer want to use SMS messaging, you can contact support@callharbor.com to have your service deactivated. However, if you want to resume SMS services in the future, you’ll need to go through the 10DLC registration process at that time.

Are You Allowed to Register?

Most businesses can register for 10DLC, but some industries are restricted due to the new regulations. If your business involves high-risk financial services, lead generation, debt collection, “get rich quick” schemes, gambling, or any activities related to sex, hate, alcohol, firearms, or tobacco, you may not be eligible to use 10DLC.

Note: Alcohol and firearm-related messages are allowed as long as proper age verification is in place. Tobacco-related messages are allowed on long codes but not on toll-free numbers. Vaping-related messages, however, are prohibited on both.

Final Thoughts

The new 10DLC system offers businesses an effective way to send text messages to their customers while complying with carrier regulations. If you want to continue using SMS messaging, be sure to register your brand and campaigns. Following these guidelines will help ensure that your messages get through to your customers reliably and without being flagged as spam.
