Money Transfering

Western union or from the main bank of Sri Lanka to any one here.
Look for IBAN codes or swift codes through Google to help you.

Try transferwise.com

I use that to transfer money where I need - better rates and faster than banks.

Best to check with your bank first and provide them with the details of the currency receiver as they may not have the facilities or authorisation to send money to a particular bank.   There also may be limits on the amount of currency your are transferring as each country has laws and regulations that control this type of transaction.

Also note there will be fees and changes in currency exchanges (on a day to day basis) that will affect the amount of currency actually deposited with the receiver.

You will require the SWIFT code of the receiving bank (use google) which is an International code that identifies a particular bank overseas.

Otherwise there are a plethora of money transfer organisations (Western Union) that operate internationally.

I entered "How to transfer money from Indonesia to Sri Lanka" and received lots of options that appeared legitimate and credible.

Hope this helps.
