The official passport could not be found.

Maybe the query method is wrong. The correct query method is:

1, I need to consult with the local exit-entry administration office with valid documents.

Passport number is a personal secret. Generally, only individuals can provide documents that can prove their identity, and the entry-exit administration department can help you check. Passport number, like ID number, serves as a sign to prove identity.

3. China's passport number is 9 digits, 1 digit +8 digits. The English letters at the beginning of your passport number represent the nature of your going abroad: P starts with a business passport, D with a diplomatic passport, S with a business passport, G with a personal passport, H with a Hong Kong SAR passport and a Hong Kong citizen's home visit permit, and M with a Macao SAR passport and a Macao citizen's home visit permit.
