What Is A Long Code?
A long code is a 10 digit phone number used for communication between two or more individuals. Long codes have the advantage of being more recognizable than a short code, and their main advantage is that the same number can be used for both calling and texting.
Types of Long Codes
P2P Long Code
P2P (peer-to-peer) long codes are 10 digit numbers you use to have 1-to-1 conversations with your customers. Currently these are only available via API.
Toll-free numbers give you the same presence as that of a national company. Toll-free numbers are also great because they give you the power and flexibility of a dedicated short code but are much cheaper and faster to requisition.
A2P Long Code
A2P (application-to-person) long codes are local 10-digit phone numbers that can send mass messages for commercial purposes. Set to be available sometime in 2019, they will essentially work like a dedicated short code, allowing you to use all of the features of an SMS platform but for a fraction of the cost.
