Introduction to 10DLCs
Learn what 10DLCs are, why you might use them, and how they help you send compliant messages to recipients in the United States.
What is a 10DLC?
A 10DLC (10-digit long code) is a local phone number approved by US mobile carriers for A2P (Application-to-Person) SMS and MMS messaging. Through SMSBlast.io, businesses can register 10DLCs to send compliant and reliable messages to customers across the United States.
10DLCs use the same 10-digit format as standard mobile numbers, making them familiar and trustworthy for recipients.
Why Use a 10DLC with SMSBlast.io?
- Better Deliverability – Messages sent through 10DLCs are less likely to be blocked or filtered.
- Cost-Effective – More affordable than dedicated short codes while still offering strong performance.
- Carrier Compliant – Fully aligned with US carrier regulations for business messaging.
What is a 10DLC Campaign?
A campaign describes the type of messages you plan to send—such as customer service updates, alerts, or promotions—and includes a few examples.
To use a 10DLC in the United States, you must register a campaign through SMSBlast.io. Every 10DLC must be linked to an approved campaign.
