I think there’s a 7 and a 1 or two, and maybe a 0 or something. I looked it up once and just three apartments share it. ---

Nope. I’m not making room for that in my head, until they make me anyway. ---

I’m afraid I do not know them. Furthermore, ZIP codes are meaningless, [as revealed by Newman in Seinfeld!](http://twistedsifter.sifter.netdna-cdn.com/wp-content/uploads/2012/04/newman-zip-codes-seinfeld.jpg) ---

Yes, as I frequently see it on incoming mail. ---

Yes, it’s 5934. I didn’t know of the DPB. I’ll look for that in my mail. ---

I don’t have one. My second-last postal code was M8Y 3M3, though. 🙂 ---

No but back when I was filling out forms often I did. ---

Not a clue. On the rare instances I need it for something, I hunt around for a piece of incoming mail with it on there. ---

I reported earlier that I know mine. I almost always use it. It’s printed on my checks and on personal return labels. And when sending mail I usually look up the recipient’s +4 and use it. I don’t know if it makes any difference in postal delivery speed or accuracy, but I just use it. Probably has something to do with me being former military, and a briefly former postal employee. ---

I send out a few hundred DVDs every year, and always include the +4, even though I hand-address the labels. I could use stickers, but I hate running stickers through a printer - one sticker peeling off seems to be inevitable. It’s not a huge hassle, and does seem to speed delivery. ---

I do. Our ZIP code is a palindrome (or whatever the numeric equivalent is), as is the _other_ side of the street’s +4 code. Ours breaks the symmetry. Actually, that kind of brings up a question. By ‘other side of the street’, that’s how the post office does it. But we’re at the very end of a mile-long cul-de-sac, and our driveway is pretty much in the middle. Given the rural nature of the area, I never use the +4 … could I just start using the opposite side of the street’s code for elegance’s sake, or would that disturb the time-space continuum? ---

I know mine. When I used it yesterday the postal worker told me it was an incomplete address. ---

No, the mail gets to me fine without it, so there’s not much motivation. ---

It’s been decades since I left the house where I grew up and my parents are long gone, but I still remember the four-number code at the end. But I don’t remeber any part of the Zip codes where I lived elsewhere the US after leaving home. And we don’t have the four-number extension over here. I also remember the telephone number we had when I was growing up. ---

For some reason, two different ones wind up going to me. I know one, because it’s in a pattern, but not the other. I now get more of the one I remember, but I’m not sure if that’s because it’s right, or because it’s the one I put when filling out my address.
