What is 10DLC?
A 10DLC refers to a 10-digit long code in Application-to-Person (A2P) messaging. A 10DLC is a 10-digit phone number for a business that looks like a standard 10-digit phone number with a geographical area code. 10DLCs, toll-free numbers, and short codes are the three primary number types businesses use to engage in A2P text messaging.
10DLC differ from toll-free phone numbers, which have an “800” area code (rather than an area code that is local to a geographical area), and from short codes, which are 5-6 digits. 10DLC requires a special registration process and must comply with US messaging guidelines.
Pros for using 10DLC numbers
10DLCs may improve SMS engagement rates. (Receiving a text from a 10-digit number with a local area code can feel more personal than receiving a text from a 5-digit short code or toll-free number.)
10DLCs have much lower costs than dedicated short codes, and in many cases are included for free.
Unregistered 10DLCs typically have better delivery rates than unregistered toll-free numbers.
Cons for using 10DLC numbers
The registration process costs $15/month (as opposed to toll-free numbers, which are free to register) if you have a low-volume plan.
Unregistered 10DLCs have throughputs of only 60 messages per minute, much lower than toll-free numbers or short codes.
Registered 10DLCs have throughputs of around 150 messages per minute, much lower than toll-free numbers or short codes.
10DLCs have a daily limit of around 2,000 messages.
10DLC registration requires that your business/organization has an EIN/tax ID, so it is not always a good solution for sole proprietors or new businesses.
10DLCs aren’t as convenient as dedicated short codes, because they are longer numbers.
10DLC throughput and limits
10DLCs will give you the lowest throughput, at 150 text messages per minute.
The daily limit for 10DLCs is 2,000 messages per day, but can in some cases this can be increased (increases may incur fees from the mobile carriers).
Summary
10DLCs allow for sending mass text messages at an affordable cost, using a local area code which can feel more personable to recipients. Though these benefits make 10DLC an excellent SMS solution for many businesses, MTA generally recommends a toll-free number since toll-free numbers are free and have higher messaging speeds.
