In our case, the postal code (Canadian) and almost any other piece of data is uniquely identifiable. Through a quirk in the layout of our street, my wife and I have the only house in our postal code. Add age, gender, birth month, hair colour, t-shirt size... pretty much anything, and you’ve reduced from 2 possibilities to 1.
I still want to try dropping a letter in a mailbox from a different city with just our postal code written on it and see if it arrives.
