Is it okay to stay in a hotel under someone else's name in Korea?

You can't stay in a hotel under someone else's name in Korea. In South Korea or other countries, it is not allowed to use someone else's name to stay in a hotel, because it will involve identity fraud and illegal behavior. Generally speaking, hotels require guests to provide valid identification documents, such as passports or ID cards, to ensure the interests of hotels and guests. If you don't have legal identity documents, you should first apply for relevant documents to ensure your legitimate rights and interests and abide by local laws and regulations. If you use someone else's name to stay in a hotel, it will lead to inconsistent identity information, and even be suspected of fraud, theft and other illegal acts.
