Do hotels file TM30 reports on foreigners using a Thai driving license instead of a passport?

The TM30 is a mandatory report that hotels must file for foreign guests, even if they use a Thai driving license. While hotels typically request a passport for check-in, some may accept the driver's license, which includes the holder’s Thai address. Immigration is aware of these reports, and failure to file a TM30 can lead to issues during future immigration encounters. Users suggest always having a passport on hand to avoid complications, as practices may vary between hotels and immigration offices.
