The number portability information is used to announce that the user corresponding to the terminal number has ported the number to the operator system. The number portability transfer information is stored in the blockchain account book of the number portability transfer announcement blockchain network, and can be retrospectively queried. Wherein, the number portability information includes the terminal number and identification information of the current operator system corresponding to the terminal number. The current operator system corresponding to the terminal number is the operator system to which the terminal number is ported.
