At what age should I check in for a hotel ID card like Home Inn, or can I open it with my ID card?

You can open it with your ID card, but under 18, you must be accompanied by a guardian to open a room alone.

How old can I go through the hotel check-in regulations without an ID card?

Relevant laws and regulations clearly stipulate that you must show valid documents and register with your real name when staying in a hotel. Article 6 of the Measures for the Administration of Public Security in Hotel Industry of the Ministry of Public Security stipulates that hotels must register when they receive passengers. At the time of registration, the passenger's identity documents shall be checked and truthfully registered in accordance with the prescribed items.

Passengers must hold their valid identity documents when staying, one for each person. Minors' accommodation registration, like adults, requires real-name registration and valid identity documents. Minors who have not applied for resident identity cards can register their accommodation in the household registration book. Real-name registration system is not only the need of public security management, but also the need to protect the legitimate rights and interests of minors.

In order to solve the problem that passengers without valid identity documents can't stay in hotels, the police have launched a convenient green channel to handle temporary id card documents 24 hours a day. Domestic passengers without valid identity documents, including minors, who need to stay, can issue identity certificates to the local police station of the hotel and register.
