I believe that the 9-digit zips are a unique identifier to your exact house location in the city. That knock you will be hearing on your door will probably by the F.I.B.s

No,that's the thing...I don't live in her district.I gave a false address (everything else was real). I suppose the FIB could easily track me down...but they won't find me at the address I gave.

Fortunately 9-digit zip codes are not that precise. They represent a sub-area within the 5-digit area. I have used a similar trick to get around the zip code qualifier ... search for the town hall or county courthouse address and use that zip code in your email.

But as other commenters have said, most emails are never seen much less read by the addressed congress-critter. A cipher in their office reads it, harvests the return email address for (unending) funding requests, and then the email is destroyed.

OK?

Pilgrim’s Progress is correct about why it required a nine digit zip code to utilize the email system. Now they know where you live if they aren’t able to identify you by email address or ip address.
