In a flurry of New Year enthusiasm for a bit of US investment I've just set up accounts with these entities. Trouble is I now have my doubts as to whether I can actually get any USD into the IB account using this path! Are there folks here who have been successful with this mechanism? If so it would be great if you could tell us how; otherwise feel free to continue reading... I have kicked off a small test transfer but now wonder will make it 'across': IB gave me what they call a virtual account number but this includes one non-numeric character and is not accepted by the TransferWise 'form'. A bit of googling inspired me to just drop that character ('U') and hope for the best. (There is a routing number at least anyway). IB have subsequently told me that I could just include the bank's own account number and include my account info in the payment details. But there is no option for payment details in the TW form, other than a 'reference' field, which will - just about - take my account number. IB have also said that transfers from the likes of TW can be rejected as they 'are not sent in the client's name' and/ or 'not sufficient payment reference' is included. Given that the account name is 'Transferwise FBO <my name>' I would hope the first of those concerns is covered but overall, not looking terribly promising. In the meantime I haven't cancelled my first transaction attempt - I should know later today whether it gets through, and can share this if of interest or still relevant by then.
