It's for a random person.
We've just moved into a new build and there's 20 other houses so may be one of the neighbours but if it is I don't recognise them.
I'll let DVLA know but is there anything else to be aware of?
I'm thinking if anyone knocks and ask for it to say no and that I've returned it. As it's a new build it's not recognised on DVLA so you have to input the address manually.
And yes. I did open it even though it wasn't in our name
