all that means they have been registrerd in the same town/city


and the 454 is older than the 464 by ten cars




just like J 444 ESR when the numbers get to J 999 ESR the next reg will be J 1 ESS because ES will be the town/city where the cars registerd

DVLa will keep back ( 1-99 for personal plates nomaly you will hardly see any plates less than 7 digits normaly

years ago they just put the next reg on regaurdless
