When using TransferWise.com to send money to us you should use our domestic ACH routing number:
Electronic (for Direct Deposit and Automatic Payments) 081904808
Because TransferWise will collect your money in your home country but pay us through their own US bank account via ACH (They do not send money internationally). So Transfer wants to initiate a US to US transfer to us. In this case rather than use our wire routing number, please use our electronic funds transfer routing number shown above and try again.
