Why can’t I find records of traveling abroad on business?

Passport numbers are kept confidential and valid ID is required.

1. Passport number confidentiality: Passport number is a personal secret while traveling abroad. The information can only be checked if you provide your ID card, and cannot be checked by anyone else.

2. A valid ID is required: To check the overseas records, you need to hold your ID card, passport and other relevant documents to find the information. It is difficult to find out the information without the person and ID.
