Opening a Thai bank account is one of those tasks that sounds simple until you’re standing at a counter being told “no” for a reason nobody can quite explain. It is possible as a foreigner, plenty of expats and long-stay visa holders do it every month, but the process is genuinely inconsistent: what one branch of Bangkok Bank asks for can differ from what another branch of the same bank asks for a few kilometres away. A local bank account matters for more than convenience, it usually unlocks better exchange rates on incoming transfers than repeated ATM withdrawals on a foreign card, lets you pay rent and utility bills by transfer instead of cash, and is often a prerequisite for signing a longer lease, buying a Thai SIM plan under contract, or setting up certain visa-related financial requirements. This guide covers which banks foreigners actually use, what documents branches tend to ask for, why tourists have a harder time than they used to, and how to improve your odds if you get turned down. As with anything YMYL-adjacent involving money, we’re a guide, not the bank, requirements change and vary by branch, so verify specifics with the bank directly before you go.

Which banks do foreigners use in Thailand?
The four major retail banks foreigners most commonly open accounts with are Bangkok Bank, Kasikornbank (KBank), SCB and Krungsri. None of them is uniformly “the easy one”, foreigner-friendliness depends far more on the specific branch and the officer you get than on the bank brand itself.
| Bank | Commonly reported notes |
|---|---|
| Bangkok Bank | Thailand’s largest bank by assets; widely used by long-stay expats and often cited as having more foreigner-experienced branches in Bangkok and tourist areas |
| Kasikornbank (KBank) | Popular mobile app (K PLUS); branches vary widely in foreigner experience, some accept tourist-visa applicants, others don’t |
| SCB (Siam Commercial Bank) | Large branch network; some branches in expat hubs have a track record with foreigners, but requirements reported as stricter at others |
| Krungsri (Bank of Ayudhya) | Less commonly used by foreigners than the above three, but workable at branches used to expat customers |

What documents do you actually need?
At minimum, every branch wants your passport. Beyond that, the picture gets messier. The most reliable route is a long-stay visa, a Non-Immigrant O, O-A, ED or Business visa, rather than a tourist visa. On top of the visa, an increasing number of branches now ask for one or more of the following:
- A work permit, which strongly improves your odds if you have one
- A Certificate of Residence from Thai immigration or your embassy, if you don’t have a work permit
- Proof of address, a lease agreement, a TM30 receipt, or sometimes a hotel booking
- A Thai mobile phone number, since SMS verification for the mobile banking app usually requires one
Because no two branches ask for exactly the same combination, the practical advice from long-time expats is simple: bring more documents than you think you’ll need. Passport, visa page, work permit if you have it, proof of address, and a local number, then let the branch tell you what’s actually required rather than guessing in advance.
Can tourists open a Thai bank account?
Sometimes, but treat it as the exception rather than the plan. Certain branches, historically concentrated in Bangkok and other tourist-heavy areas, have opened accounts for travellers on a tourist visa, occasionally with the help of an agent who has an existing relationship with a specific branch. That door has narrowed: since roughly 2023-2024, Thai banks have tightened anti-fraud and know-your-customer checks, and many branches now decline tourist-visa applicants or push them toward a longer-stay visa first.
If you’re visiting on a tourist visa and want an account anyway, ask in expat Facebook groups or forums specific to your destination which branch is currently working for tourists, results change often enough that last year’s tip may already be stale. Bring every document above, and go in expecting it might take more than one attempt.
Why does the process vary so much by branch?
There’s no official published rulebook that differs by branch, formally, head office policy applies everywhere. In practice, individual branch managers and staff interpret anti-fraud and compliance guidance with real discretion, especially around what counts as sufficient proof of address or ties to Thailand. A branch in a small provincial town that rarely serves foreigners may default to caution and ask for more, while a branch inside a Bangkok mall used to expat customers daily may move you through with less friction. This is genuinely frustrating, and it’s also just the reality: the honest fix is persistence, not finding a secret trick.
Part of the tightening also traces back to nationwide anti-mule-account crackdowns, Thai banks have faced regulatory pressure to curb accounts used for scam and money-laundering transfers, and foreign applicants without a work permit or long visa history can look, on paper, similar to the profile banks are now trained to scrutinise. It isn’t personal, and it isn’t really about you, it’s a side effect of a broader compliance push that happens to make an already inconsistent process feel even more unpredictable for legitimate long-stay foreigners.
What do you get once the account is open?
A standard Thai retail account comes with a debit card usable at ATMs and for card payments, and a mobile banking app for transfers, bill payments and balance checks. Most banks also let you register for PromptPay, Thailand’s QR-code system that now handles the majority of everyday payments, splitting a restaurant bill, paying a market stall, sending rent to a landlord. Together, these three cover almost all routine banking without repeat branch visits. If you’re setting up a Thai number to register for the app or PromptPay, our Thailand SIM card guide walks through where to buy one and what it costs.
Opening deposits are typically modest, commonly in the range of ฿500-฿2,000 (US$15-$60) depending on the bank and account type, and ongoing costs are generally low: a small monthly fee if your balance falls under a minimum threshold, plus the same ATM and transfer fees that apply to Thai customers generally. None of this is exotic or foreigner-specific pricing, the friction is almost entirely at the account-opening stage, not in what it costs to run the account afterward. Confirm current minimums and fees with the branch when you apply, since they’re revised from time to time.
How to improve your odds
- Try tourist-friendly or expat-heavy branches first. Branches in central Bangkok, near major coworking hubs, or in cities with large expat populations tend to have more staff experience with foreign applicants than small local branches.
- Ask in expat groups before you go. Online communities for Bangkok, Chiang Mai and other expat hubs regularly discuss which specific branch is currently accepting foreigners and what it’s asking for, that current, hyper-local intel beats any general guide, including this one.
- Go early and go in person. Mornings tend to have shorter queues and less rushed staff, both of which help when your application needs an unusual document check.
- Get a Certificate of Residence in advance if you don’t have a work permit, arriving with it already in hand avoids a wasted first visit.
- Try a second bank or branch if you’re turned down. A “no” from one Bangkok Bank branch doesn’t mean SCB down the street will say the same thing, or that another Bangkok Bank branch across town won’t.
If you’re weighing this alongside your visa and long-stay plans in general, it’s worth reading up before you commit to a city: our Bangkok digital nomad guide and Chiang Mai digital nomad guide both cover the visa and paperwork side of settling in longer-term, and banking tends to follow the same path as your visa status.
The honest downsides
This process has real friction, and it’s worth naming plainly. Requirements are inconsistent across banks, branches and even staff on the same day, so you may need more than one attempt. Tourists have a harder time than they used to, and some tourist-visa applicants will be turned away no matter which branch they try. Documentation demands keep expanding, a work permit or Certificate of Residence that wasn’t asked for last year might be required this year. And nothing here is guaranteed, banks can and do change policy without public notice, which is exactly why you should verify current requirements directly with the bank before making a special trip.
