Long codes are 10 digit virtual mobile numbers that are used for two-way communication. Since these are globally accessible i.e. the customers/recipients can access from international locations, they are charged nominal SMS charges only.
There are two types of long codes.
Dedicated Long Code - Clients are assigned an exclusive long code for their business, which works for their applications only. I offers scope for unlimited keywords and applications.
Shared Long Code - Clients share the long code with other businesses. Each business is assigned a particular keyword and the responses are mapped accordingly.
