Long codes, also known as long numbers, are full mobile telephone numbers (for example, 1408 7654321 or 447624803588) that can be used for 2-way SMS applications. They look like normal subscriber numbers but are actually virtual and are assigned to an application to ensure correct delivery of MO messages. 

In the United States, these may also be referred to as 10DLCs (or 10-Digit Long Codes).  See 10DLC.
