Is the Thai Morchana app mandatory for travelers arriving in Thailand?

The Thai Morchana app is primarily a contact tracing tool designed to monitor COVID-19 exposure. While technically compulsory for hotel check-ins in Thailand, experiences vary significantly. Some travelers reported being required to download the app upon hotel arrival, while others stated they were never asked for it. The necessity of the app often depends on the specific hotel or resort policies, leading many to suggest that travelers might not face strict enforcement in all situations.
