Banking in Chiang Mai: Regulator, THB Accounts & Transfers
Banking in Chiang Mai is governed by Thailand-wide rules: Bank of Thailand (BOT) oversees regulated providers, the Thai baht (THB) is the local currency, and domestic payments use a specific account format and rail. Here is what that means in practice, each point tied to its official source.
The regulator to check
In Asia, regulation is national — the body to check for a Chiang Mai provider is Thailand's.
Bank of Thailand (BOT)
Payment service providers in Thailand must hold a licence from the BOT under the Payment Systems Act. Verify its licensed status before you hold any balance with a provider.

To receive or send money locally, Chiang Mai accounts use Thailand's standard details.
- Currency:
- Thai baht (THB)
- Local account format
- Thai transfers use the recipient's bank, 3-digit bank code, and account number; PromptPay payments can use a phone number, national ID, or wallet ID linked to the account instead.
How domestic transfers move
Moving money within Thailand runs on a defined payment system.
PromptPay enables instant 24/7 interbank transfers using proxy identifiers; standard interbank transfers settle in batch windows. Provider limits apply, and the BOT caps instant-transfer amounts.
Before you open an account
- Confirm the provider is authorised by Bank of Thailand (BOT) before depositing funds.
- Transact in Thai baht (THB) and check the provider's rate and fees for any conversion.
- Use Thailand's domestic account format exactly as issued when sending or receiving locally.
- Check the provider's cut-off times and limits on the local payment rail before relying on instant settlement.
