What is a 10DLC?
A 10DLC (10-digit long code) is a type of local phone number that you can register to send A2P (Application-to-Person) SMS and MMS messages to people in the United States and Canada. 10DLCs are authorised by mobile carriers for business messaging, helping you reach your audience reliably and compliantly.
10DLCs use the same 10-digit format as regular mobile numbers, making them familiar and trustworthy to recipients. They are only usable for messaging within North America (specifically the USA and Canada).
Why choose a 10DLC?
Better deliverability: Messages sent via 10DLCs are less likely to be filtered or blocked compared to standard long codes.
More affordable: 10DLCs are generally cheaper than dedicated short codes while still offering good performance.
Carrier compliance: 10DLCs meet US and Canadian mobile carrier regulations for business messaging.
What is a 10DLC campaign?
A campaign explains the type of messages you plan to send (for example, customer support updates or promotions) and provides a few sample messages.
If you plan to send using a 10DLC in the US, you must register a campaign. Campaigns are not required in Canada.
US carriers require campaigns to make sure messaging is clear and legitimate. Every 10DLC must be linked to an approved campaign.
Giving clear, accurate information when registering helps you get faster approval and better messaging speeds.
Can overseas businesses use 10DLCs?
Yes. While 10DLCs are for sending messages to recipients in the United States and Canada, you can register and use them if your business is based in an eligible country outside North America.
