What details do I need to send money to Indonesia?

For a bank transfer: your recipient's full name exactly as it appears on their bank account, the name of their bank, and their account number.

For a GoPay, OVO or DANA wallet: the holder's full name as registered and the mobile number the wallet is registered to. Enter the number with its country code and without the leading 0, for example 62 812 3456 7890 for an Indonesian number or 61 412 345 678 for an Australian one. If the country code is missing, the number can be read as another country's and the top-up comes back as "number not registered".

The bank or wallet checks the name against the account, so a nickname or missing name can cause a return.
