Opening a bank account in Thailand as an expat

In Bangkok you can live for a few weeks on a foreign bank card. But as soon as you settle, a local account quickly becomes essential: rent is often paid by transfer, small shops display a payment QR code, and Thai banking apps have become the most common way to pay. This guide presents how it generally works and the documents usually requested. Conditions vary between banks and branches: treat it as preparation, not an official checklist.

1.Why open an account in Thailand?

• Pay rent and bills without international transfer fees.
• Pay by QR code in shops, restaurants and markets, through your bank's app (the national instant payment system, PromptPay, is widely used).
• Receive a salary if you work for a company in Thailand.
• Avoid fees for withdrawals and currency conversion every time you use a foreign card.
• For some visa procedures, proof of funds held in a Thai bank may be requested.

2.The main banks

The major Thai banks (Bangkok Bank, Kasikornbank, Siam Commercial Bank, Krungsri, Krungthai, among others) have branches all over Bangkok, including in shopping malls, often open at weekends. All offer a full mobile app. The choice depends mainly on which branch will accept your application, the language spoken at the counter and the quality of the app in English.

3.Documents usually requested

Requirements vary by bank, branch and your situation. You will often be asked for:

• your passport, with a valid visa or extension of stay;
• proof of address in Thailand: lease and, depending on the case, TM30 receipt or a certificate of residence issued by immigration;
• a Thai phone number, essential for the app and security codes;
• a document related to your situation: work permit and employer letter, school enrolment letter, or other proof depending on the visa;
• sometimes proof of address in your home country or a reference letter.

On a tourist stay or visa exemption, opening an account is often refused or very limited. With a long-stay visa and consistent documents, it generally goes smoothly.

4.How does opening an account work?

1. Call or visit the branch to ask which documents are required for your case.
2. Bring originals and signed copies.
3. The staff member fills in the forms with you, opens the account, and usually gives you a debit card and a passbook.
4. Install the app on your phone with your Thai number, often on site with the adviser's help.

Allow time: depending on how busy the branch is and the checks, it can take a good part of the morning.

5.Receiving money from abroad

To fund your account from abroad, you can use a standard international transfer or a specialised transfer service. Compare fees and the exchange rate applied. If you are transferring funds to buy property, the procedure is more regulated: the transfer reference and the proof issued by the Thai bank matter. Our guide Buying in Bangkok: from first contact to handing over the keys covers this point, to be checked with your lawyer and bank.

6.Security and good habits

Thai banking apps are convenient, but scam attempts (fake calls, fake messages, fake links) exist as everywhere:

• your bank will never ask for your PIN or password by phone or message;
• do not install an app from a link received by message;
• turn on notifications for every transaction.

7.What if you are refused?

A refusal is not final. It often depends on the branch, a missing document or the type of visa. You can try another branch or bank, wait until you have your extension of stay, or ask your employer for a supporting letter. Meanwhile, a fee-free foreign card and a transfer service let you live normally.

8.Understanding the app and everyday payments

Once the account is open, the banking app becomes your main payment tool:

• pay by QR code: scan the code shown by the merchant, check the payee name and amount, then confirm;
• make a transfer: to an account number, or to a phone or ID number registered with the instant payment system;
• pay bills: electricity, water, phone and internet can often be paid in the app, or by scanning the bill's barcode;
• withdraw without a card: some banks let you withdraw cash at an ATM with a code generated in the app.

For rent, ask the landlord for their bank details in writing and keep the confirmation of each transfer: it is your proof of payment.

9.Limits and caps

Accounts opened by foreigners may have transfer or payment limits, adjustable in the app or at the branch. If you are planning a large payment (deposit, furniture), check your limit a few days beforehand. Likewise, warn your home bank before a large transfer to Thailand to avoid a security block.
