Short answer: yes, bring it. Every licensed money changer in Thailand is required to record identification for exchange transactions.
Why they ask
Thailand regulates foreign-exchange businesses through the Bank of Thailand, and licensed operators must keep records of who exchanged what. The counter staff will typically scan or photograph the identity page of your passport, or type the number into their system.
This is not a scam and it is not optional for them. A shop that does not ask is worth being cautious about.
What is accepted
- Passport — always accepted, the standard document for visitors.
- Photo of your passport on a phone — very commonly accepted for small amounts, but entirely at the shop’s discretion. Larger branches and mall locations are stricter.
- Thai ID card — for residents.
- Driving licence from your home country — usually not sufficient on its own.
How to spot a licensed shop
Licensed money changers display a permit issued by the Bank of Thailand at the place of business. It is printed on blue and white watermarked paper with an embossed seal in the lower right corner.
Every shop listed on THX is a licensed operator that publishes its rates publicly — that is the condition for being included at all.
Practical advice
- Carry the physical passport when you plan to change a meaningful amount. Many hotels no longer hold passports, so this is usually not an inconvenience.
- Keep a photo as backup on your phone for small transactions and for the walk to the shop.
- Keep the receipt. Licensed shops always issue one. It is your only evidence if a count is disputed later.
- Count at the counter, before you step away. Staff expect this and will wait.
Large amounts
There is no everyday limit that affects normal travellers. For very large sums, expect additional questions and paperwork, and understand that a small booth may simply not hold enough baht on hand. If you are changing the equivalent of several thousand US dollars, a head office branch is a better choice than a mall kiosk.
One thing that is not required
You do not need a Thai bank account, a local phone number, or a hotel booking to exchange cash. Anyone with valid identification can walk in.
