Non-transitory computer-readable recording medium storing computer-readable instructions for first server, and non-transitory computer-readable recording medium storing computer-readable instructions for terminal device

A non-transitory computer-readable recording medium storing computer-readable instructions for a first server, wherein

• the first server is configured to provide a first service,
• the first server comprises a processor and a first memory,
• wherein the computer-readable instructions, when executed by the processor, cause the first server to:
• receive, from a first external device, user related information for providing a second service different from the first service to a user;
• receive, from a second external device, a service subscription request that requests a subscription to the first service;
• in a case where the user related information is received from the first external device, the service subscription request is received from the second external device, and first registration information is in a second memory in association with the user related information as information for providing the second service to the user, acquire the first registration information from the second memory,
• wherein in a case where the user related information is received from the first external device, the service subscription request is received from the second external device, and no registration information is in the second memory in association with the user related information as information for providing the second service to the user, registration information is not acquired;
• and
• in a case where the first registration information is acquired from the second memory, store the first registration information as information for providing the first service to the user in the memory in association with the user related information.

A non-transitory computer-readable recording medium storing computer-readable instructions for a terminal device, wherein

• the terminal device comprises a processor,
• wherein the computer-readable instructions, when executed by the processor, cause the terminal device to:
• send a second server a sending request including user related information related to information for providing a second service to a user, wherein the second service is different from a first service provided by a first server, and the sending request is a signal that requests sending of registration information stored in the second server in association with the user related information;
• in a case where the sending request is sent to the second server and specific registration information is in the second server in association with the user related information, receive the specific registration information from the second server, wherein in a case where the sending request is sent to the second server and no registration information is in the second server in association with the user related information, registration information is not received from the second server;
• in a case where the specific registration information is received from the second server, send the specific registration information to the first server;
• send the user related information to the first server;
• and
• send the first server a service subscription request that requests a subscription to the first service, wherein in a case where the specific registration information is received from the terminal device, the user related information is received from the terminal device, and the service subscription request is received from the terminal device, the first server is configured to store the specific registration information as information for providing the first service to the user in association with the user related information.
