I wouldn't be surprised if 90210 is outrageously over represented...
Or 02134.
I like to use '90210'
When I was a teenager in the 90s I worked at a chain store that had the policy of asking customers for their zip code at checkout to collect data on who was shopping. People sometimes would get really mad (and I mean really mad) that I was asking them, and since it was before the internet went mainstream people had not been conditioned to give out personal information yet/were unfamiliar with big data/weren't getting anything in return for their zip code. So in order to confuse the system (and avoid upsetting anyone - I am conflict avoidant) I would solely use 90210 as the zip code of all our shoppers, despite being on the other side of the country from Beverly Hills. I conspired to get my coworkers to do the same. A quarter of a century later I still feel minor gratification that I stuck it to the man.
I'm partial to giving my address as 1060 West Addison St., Chicago, IL 60613.
That Wrigley Field, for those not from Chicago.
Wrigley Field is the home of the Chicago Cubs, a Major League Baseball team, for those unfamiliar with American sports.
When a store offers the option of entering a phone number instead of using a physical "loyalty card", I've found that XXX-867-5309 nearly always works, where XXX is your local area code (for me, it's 206).
My wife and I went on vacation and didn't have the proper "club card" for the store. 867-5309 worked as a phone number, and was issued to a "Jenny".
