A few of us went to the main post office here in town to learn a bit about mailpiece design. (Yes, the one-word mailpiece is, according to the post office, a legitimate term, and since I’m discussing postal issues, I’m deferring to its spelling preference.) We even scored a tour. The bummer was that we were there during off-peak hours, so all the belts were stationary, no whistles were toot-tooting and no one was shouting orders to and fro. In fact, there were very few folks around. But there were some chicks (dyed bright green and orange, no less) in cartons, chirping their little lungs out, waiting to be shipped out in time for Easter.

But I digress.

We learned about acceptable sizes for letters and postcards — including the “official” tapping-an-envelope-through-a-slot-to-see-if-its-size-is-legit method — and whether or not we should design an envelope out of metallic paper (not recommended); but what really caught my attention was the shtick about addressing a letter or parcel, particularly the punctuation (or lack thereof) within an address.

USPS-approved address format

The United States Postal Service® (USPS) prefers no punctuation in an address. There are always exceptions to rules, and its listed exception is that it is OK with the hyphen in the ZIP+4 Code (64110-7346). It’s unofficially OK with apostrophes in, for example, a city’s name (Lee’s Summit) or other such necessary punctuation (Stratford-upon-Avon). But commas and periods are unnecessary and clunk up the system. That means no periods in PO Box, no periods with N or S Broadway and no comma between the city and state. That’s right: It’s Lawrence KS and New York City NY.

You might have noticed in the above example that the USPS really, really likes uppercase letters. Now, there are those of us who think that a lot of uppercase letters makes it look like the author has some serious anger-management issues that need to be addressed. But try to think like a postal machine — the monstrosity that sucks in your little hand-written letter with fancy calligraphy, tries to interpret your fancy curly-cue p’s and twice-crossed t’s and then spits it into the correct bin that sends said letter to exactly where you want it to go. That’s a lot of work for that hunk of metal to accomplish, all for the cost of your 42¢ stamp. (Is it still 42¢?)

The point is, if you absolutely need your letter/note/package to get to its destination, try to write legibly. That fancy USPS machine is somehow able to read handwriting as easily as the printed word, but it would appreciate your effort at making its job easier. You don’t have to write in all caps unless you want to, but at least make sure that the address is easy to read. And if you can stomach the style, choose sans serif over serif fonts.

The machine reads the address from the bottom up. And frankly, what I got from the information segment of our field trip was that the mail gets delivered based on the last two lines; everything above that is fluff. Make sure that the very last line has the correct city, state and ZIP code (with +4 Code if you have it, but no worries if you don’t). And make sure that the second-to-last line (that’s penultimate to you word nerds) has the correct address.

If you have a P.O. Box and a physical address, use only one — and, again, please remember to lose the periods in the P.O. If you feel as though you absolutely must put both addresses on the letter or package, then place the one you really want the package to go to on the line directly above the city, state and ZIP information, because that’s the line the machine will read.

One last thing to keep in mind is placement of the address. The USPS machine reads a certain area of each letter, post card, flat or package. For example, if you have a letter, don’t let your writing slip into the furthest-right ½ inch or below the bottom 5/8 inch of the envelope; the machine’s reader will not pick any information up in those areas and your thank-you note will not get to Aunt Gurtie in time to make her an auntie proud of her young relative’s manners.
