12Go promo codes (October 2026), plus how to pay less for Thai buses, trains & ferries
We found no 12Go promo code on any official page. Here's what 12Go officially offers, and how to get the cheapest bus, ferry or train ticket in Thailand.
12Go promo codes we could verify
Only codes published by 12Go or an official partner. Copy a code, then confirm the discount shows at checkout before you pay.
No verified public code right now. We didn't find a code on 12Go's official pages or partner announcements, so we won't list one. See how to get the best price below.
Why there’s no code here
On 18 Oct 2026 we checked 12Go’s own pages and found no public promo code. Codes like “IMP10” circulate on third-party coupon sites, but we couldn’t trace them to 12Go or an official partner, so we don’t list them. If 12Go publishes one, it goes here with the source and date.
Official 12Go offers we did find
- KTC credit card cashback. 12Go has an official KTC promotion page offering 5% cashback for KTC cardholders. Check the page for current dates and the cap. Not yet verified — we'll update this after checking first-hand
- 12Go Thailand promotions page. 12go.asia/en/thailand/promotions collects official offers. When we looked, it included an older DTAC tourist SIM bundle (299 THB), which may no longer be current.
How to get the cheapest ticket on 12Go
- Compare operators, not just times. The same route can have several operators at very different prices. Sort by price and check the vehicle type (VIP bus, minivan, joint bus+boat).
- Look at the operator’s own price. For big routes like Bangkok → Koh Phangan, the operator’s joint ticket price (Lomprayah, for example) is often the benchmark. 12Go’s total may include a booking fee. Compare the final price. Not yet verified — we'll update this after checking first-hand
- Overnight saves a hotel night. A night bus+boat or sleeper train replaces a night’s accommodation.
- Book early for holidays. Around Thai holidays and Full Moon Party dates, the cheap departures sell out first.
- Pay in THB with a no-foreign-fee card (or Wise) to avoid conversion markups.
