Bangkok Money Exchange Guide: Comparing Ratchadamri, Pratunam and Sukhumvit Counters

Where to compare cash In Bangkok, the most useful comparison zone runs from Ratchadamri and Pratunam to Phaya Thai, with several established counters a short BTS ride or walk apart. Sukhumvit is easier if you are staying there, but check the final payout before crossing town for a small exchange. Superrich Thailand at 45 Soi Ratchadamri 1 showed 4.2 from 822 Google reviews on 31 August 2026. Recent reviews praised the rate, while lower ones repeatedly described 50–120 minute waits and different treatment of note denominations. Use it as a reference quote, not an automatic winner. Siam Exchange at 422/3 Phaya Thai Road showed 4.8 from 710 reviews. Many reviewers described fast service and competitive rates. The contrary pattern was rude service, refusal of worn notes and weak quotes for less common currencies. Vasu Exchange on Sukhumvit Road showed 4.5 from 465 reviews. Reviews often praised its speed and USD rates; low-rated reports repeatedly mentioned differences between the website and the counter, and reduced rates or refusal for old, marked or damaged notes. Comparing properly Take the exact notes you plan to sell to two or three nearby counters and ask: “For these $100 notes, exactly how many baht will I receive?” A board may quote a different tier for $50, $20 or imperfect notes. Count the baht at the counter. Keep your passport with you: reviews of all three offices repeatedly mention passport requirements. At Suvarnabhumi, traveller discussions separate the basement counters near the Airport Rail Link from the convenience desks in arrivals. If you cannot compare, change only enough for transport and check city quotes later. Thailand's central bank publishes a list of authorised money changers, so verify the legal entity instead of trusting a familiar sign colour. USDT For crypto, look up the exact operator in the Thai SEC's register of licensed digital-asset businesses. A Maps pin, Telegram contact or physical desk is not a licence. Before any transfer, get the THB payout, wallet owner, network, identity checks and receipt in writing, and do not send to a personal or unrelated wallet.
