PROBLEM TO BE SOLVED: To provide a service site to selectively inform and search new addresses of registered users for a person who has searched by using old addresses. SOLUTION: A search system for new address comprises a Web server 4 possible to connect to Internet, a database server 7 storing net information containing at least new and old mail addresses, URLs and user's names registered by a user, ID, a password and a registration date, a mail server 8 and an operation server 9 to transfer and control data to the server 7 and 8. In the system, the server 4 searches information matching with a keyword which the server 4 received from a searching person from the server 7, and if the searched information is information of the past, extracts new information with the same item, and if the searched information is new information, extracts a mail address of an appropriate registered user so as to transfer the address to the searching person after checking with the registered user for the pros and cons of notifying.
