10DLC stands for 10 Digit Long Code (often referred to as a Long Number) and is a carrier sanctioned channel for sending Application-to-Person (A2P) messages using a dedicated 10-digit wireline telephone number allocated within the North American Numbering Plan (NANP).
10DLC provides several benefits over short code and traditional long numbers:
Protects recipients from unwanted messages as the brand and campaign will be transparent to all parties in the ecosystem.
It is an ideal replacement for companies operating on shared short codes, which present a higher risk of spam, and if/when blocked ALL senders using the shared code will be impacted.
Capable of much higher messaging throughput than traditional long code messaging.
Improved deliverability rates.
Much more affordable than dedicated short codes and allows brands and businesses to use a single or pool of local numbers for their messaging campaigns to engage with customers in a familiar area code and still retain brand recognition.
Features supported on 10DLC include:
Voice capable by default (must create Voice Account)
MMS in US and Canada
Full Keyword based support– opt–in/out or set special keywords

Shortened URL – carriers may filter generic or public URLs such as Bit.ly. Recommend using a branded URL.
