Chinese Name: B23 存储转发类业务


The B23 license is defined under the VATS (Value-Added Telecommunications Services) licensing scheme in China. This license allows you to store and forward messages from one party to another. If your app, game or device uses email, voicemail, voice messaging, or faxing between two or more users, you will need this license.


The B23 license is defined in Announcement of the Ministry of Industry and Information Technology on Promulgating the Classification Catalogue of Telecommunication Services (2015) as follows:

Store-and-forward services refer to the message sending services provided for users by utilizing the store-and-forward mechanism. Store-and-forward services include the voice mail, e-mail, fax store-and-forward, etc.

Voice mail services refer to the storage, extraction, and use of voice messages and other auxiliary functions provided for users by utilizing a voice mail system which is connected with the public communication network, public data transmission network or the Internet. Each voice mail has a special mail number, and the user may deliver, receive, store, delete, forward or inform the message through a telephone, a computer or any other terminal equipment.

E-mail services refer to the services of one-to-one-point or one-to-multi-point e-mail editing, sending, transmission, storage, forwarding and receipt provided for users by adopting various kinds of e-mail transmission protocols through the Internet. Meanwhile, users are provided with various types of information exchange in a store-and-forward manner, by combining an intelligent terminal, computer, etc. with the public communication network.

Fax store-and-forward services refer to the unreal-time sending of faxes at the other end, with such faxes being controlled by the store-and-forward system set up between fax machines and between fax machines and computers of users.

The fax store-and-forward system is mainly composed of a fax work station and a fax store-and-forward mailbox, which are connected through a packet network, a digital private line or the Internet. Fax store-and-forward services include the multi-site delivery, on-time delivery, fax mail, designated receiver communication, message filing and other supporting functions.
