Klein says “simply because somebody is aware of your driver’s licence quantity isn't a motive to hurry out and alter your driver’s licence”.
He says with out different particulars comparable to expiry dates or the deal with on the cardboard, there's a restrict to what anybody can do with the data.
Nonetheless, Murray believes it’s “worthwhile excited about” altering your passport or driver’s licence numbers.
