Answer
Carry valid government-issued identification when entering clubs or age-restricted venues in Pattaya. Thailand restricts alcohol sales to people aged 20 and over, and individual venues may apply stricter door policies. A passport is widely recognised, but carrying the original creates loss risk; ask the venue or hotel what form it accepts and keep a secure copy available. Never hand your passport to an unofficial person as collateral. Venue rules, special-event controls and restricted alcohol-sale days can change. Current-detail note: Thailand updated general alcohol sales hours in May 2026, but exceptions, religious-day restrictions, licensing conditions and venue rules can still apply. Carry valid identification and confirm the current position locally.
