VLN (Virtual Long Number)
A Virtual Long Number (VLN) is a common mobile number given by mobile operators, made of 12 digits (e. g. 442312345678).
VLN works not only on a state level but also worldwide and in roaming, unlike Short Code numbers. VLN authorizes businesses and institutions to make SMS interconnections with the end users over the SMS channel.
VLNs are considered both less costly and time-consuming in their setup compared to Short Codes, but alas do not enable premium messaging services. More expensive rates may apply when sending SMS messages outside the country to the virtual long number. When used nationally, the national SMS rates are applied.
Messages that are transferred to a virtual long number can be accepted by various types of applications and serve as triggers for any future user activities.
