Banking in Medan: Regulator, IDR Accounts & Transfers
Opening and running a financial account from Medan comes down to a few local facts: the Indonesian rupiah (IDR) is the currency you will transact in, Bank Indonesia (BI) / OJK sits behind regulated providers, and domestic transfers follow Indonesia's own account format and payment rail. This guide lays out each one with the official source, so you can verify a provider before you commit.
The regulator to check
Any provider you use from Medan should be accountable to Indonesia's financial regulator.
Bank Indonesia (BI) / OJK
Payment service providers in Indonesia must hold a licence from Bank Indonesia, with prudential oversight for fintech lending by OJK. Check licences before you keep a balance with it.

Here is how a domestic account in Indonesia is addressed.
- Currency:
- Indonesian rupiah (IDR)
- Local account format
- Indonesian transfers use the bank name, a 7-digit branch code, and the account number; BI-Fast payments use an alias (phone, email, or national ID).
How domestic transfers move
Once details are confirmed, this is how a domestic transfer actually moves.
BI-Fast enables instant interbank transfers 24/7 using alias keys; QRIS standardises QR payments across providers. Availability depends on your bank's participation.
Before you open an account
- Confirm the provider is authorised by Bank Indonesia (BI) / OJK before depositing funds.
- Transact in Indonesian rupiah (IDR) and check the provider's rate and fees for any conversion.
- Use Indonesia'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.
