Which account format do I have to use for my ISA transfer to avoid rejections of my transfer?

In order for your ISA Transfer to be completed successfully, your ISA provider must validate the account number provided on the request. If the account number is invalid, your broker will reject the request.

IBKR recommends that clients review a copy of their brokerage statement to confirm their account number. We will provide below a list of some providers and their account format, however we urge you please to confirm with your broker for accuracy and any questions.
