Bangkok’s 20-Baht Train Fare Registration Begins August 25 via ‘Tang Rat’ App
Starting August 25, 2025, commuters in Bangkok can register for the city’s 20-baht flat-rate train fare through the “Tang Rat” app, ahead of the policy’s full rollout on October 1.
Deputy Prime Minister and Transport Minister Suriya Juangroongruangkit announced that Thai nationals can register using their 13-digit national ID, a valid credit or debit card, and a registered Rabbit Card. Those who choose not to register will continue paying regular fares. The minister assured that the system can handle high traffic, noting it’s modeled after the successful “Digital Wallet” platform that supported over 18 million users. Registration will remain open without a closing date.
The fare cap will apply to 13 routes across eight train lines in Bangkok and surrounding areas, covering 194 stations over a total of 276.84 kilometers. Authorities anticipate a 20% rise in ridership.
In the initial phase, Rabbit Cards can be used on the Green, Gold, Yellow, and Pink lines. EMV contactless cards (Visa or Mastercard from partner banks) will be accepted on the Red, Blue, Purple, Pink, Yellow, and Airport Rail Link lines. Commuters may need to carry two cards for cross-line travel during this phase, but the flat 20-baht fare will apply regardless. Plans are also underway to introduce QR code payment for added convenience.
This flat-fare initiative, championed by the Pheu Thai-led government and the Ministry of Transport, aims to make travel more affordable, enhance public transit accessibility, and help reduce traffic, accidents, and air pollution in the capital.
