Can I check in if I don’t have an ID card when I check into the hotel but I can provide my ID number?

You will not be able to check in if you only provide your ID number. But there are ways to solve it.

First fill in the resident identity information contact form at the hotel reception desk, in duplicate, one for the hotel and one for yourself.

Then go to the police station to obtain identity information based on the nearest police station address on the contact form, and ask the police station to issue proof of identity information and stamp it.

Finally, take this certificate back to the hotel to check in.
