Do I need to change my contact's mobile phone number?

Does the subject want to ask, "Do I (the original liaison) need to be present to change the mobile phone number of the industrial and commercial liaison?" No need.

1. If it is necessary to change the record information of the industrial and commercial liaison officer due to resignation or other reasons, the new liaison officer can directly go to the window of the enterprise registration authority to change the liaison officer with relevant certificates.

2. Online processing: directly change online in the "National Enterprise Credit Information Publicity System", and the system will send a text message to the original liaison officer's mobile phone for verification. If you can't get in touch with the original liaison officer, you can apply for changing the liaison officer in the window of the registration authority without being present in person (the original liaison officer).
