To prevent Fraud and comply with Anti Money Laundering regulations, Flywire can only send the refunds to the account used to make the original payment.
Flywire requires 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 some cases, Flywire may ask for additional documentation related to your account.
