When Pete Carr is looking at the cheque (check) while sitting in the car, the address of the TSB bank is shown with the sort code bank/branch identifier like a routing code in the US) 776041. On the encoding line at the bottom of the cheque, the sort code reads 950121.
776041 is the format for a TSB bank sort code but isn't valid. 950121 is in fact a branch of Danske Bank in Belfast.
There is also a number encoded on the bottom right, this space is left blank as in the past the amount was encoded here.
