The invention provides a method for confirming a terminal contact list, a server and a storage medium. The method comprises the steps of obtaining a contact person matching request sent by a user server, wherein the request includes a contact person number and a unique corresponding identification code; judging whether the identification code is matched with a preset standard identification code or not; if the identification code is not matched with the preset standard identification code, judging whether the contact person number is matched with a preset standard contact person number or not;if the contact person number is not matched with the preset standard contact person number, controlling the user server to send a vacant number instruction to a terminal so as to enable the control terminal to prompt that the contact person number is a vacant number in a local contact list interface; and if the contact person number is matched with the preset standard contact person number, controlling the user server to send a contact person number change instruction to the terminal so as to enable the control terminal to prompt that the contact person number has been changed in the local contact list interface. The method enables the user to timely understand the state of contact person numbers in the terminal contact list, thereby saving the telecommunication cost.
