Would an error code protect against it if both accounts exist? if the account doesn't exist then the transfer wouldn't go through.

- extraduder_ire 3y agoYes it would, since adding a check digit means there are 10x as many numbers as possible accounts, and any single digit typo or transposition can't map to a valid account number with a valid check digit. Even if a transfer doesn't go through, that transfer might be stuck pending for hours or days before being reverted, if we're talking about bank transfers.
