Flywire will require a valid proof of payment issued from the bank used to initially make the transfer to our account when you sent the funds to your institution.
The proof of payment needs to be a detailed document of the originating account. In the case of a domestic bank transfer (wires within the same country or within Europe), a simple bank receipt will suffice. For international bank transfers (wires made from country A to country B), a SWIFT MT103 (An MT103 is a standardized SWIFT payment message used specifically for cross border/international wire transfers) of said transfer will need to be provided. This document can be issued by your bank.
In the case that the bank receipt does not provide sufficient account information, our Refunds team will also ask for documentation and/or information related to your account to be able to send the funds back successfully.
Please bear in mind that the information mentioned above will always need to be that of the originating account where the funds came from, as per compliance and security reasons, that is the only place where Flywire can refund your money.
