message: The PDF link below is a page from the Domestic Mail Manual.  Currently (12/2005) the barcoding standards page is available
at http://pe.usps.com/cpim/ftp/manuals/dmm300/708.pdf and I added that to the article as a reference.  I also added a couple
of notes on the bar count of the various codes and a clarification on including the delivery point when doing the checksum.

Hi. I found this page which has a link to the POSTNET specification (and something called PLANET, which is another kind of coding, I think).  Its a USPS standard, but the link isn't a USPS page:
   http://www.triskelion-ltd.com/po-c840.pdf
you might want to put that on your page also.
That page also says you can encode longer local delivery codes (not just zip and zip+4)

I (a few edits ago) changed the lower-half bar into Unicode using box drawing techniques. This works in any Unicode-capable browser. — Xoder|✆ 16:13, May 3, 2004 (UTC)
: Since Internet Explorer does not support those characters (and it unfortunately remains the most common browser), I switched it to a different format using   and  commands on the | character.  It looks okay on all but the Chick skin (in the my preferences section).  Rossami (talk) 21:38, 4 April 2006 (UTC)

message: note to potential contributors:  it would be interesting to know why the post office adopted this bar code standard instead of any of the other more common bar code systems?
Well anonymous commenter, the US Postal Service is one of the single biggest users of robotics and automated systems. There's many different barcode systems out there, but most of them are designed for commercial usage. Postal processing equipment has to be able to scan barcodes at frequences as high as 100 times per minute, and fit in very small spaces. Jeff The Riffer 02:01, 9 May 2007 (UTC)

message: I removed a self-link to "PostNet International Franchise Corporation".  If there ever was such a corporation, it would be interesting to explain it in the article. -- Beland 15:50, 21 June 2007 (UTC)
thread_title: PostNet International Franchise Corporation

message: The example cites a ZIP+4 of 55555-1237 which with the check digit of 2, gives "an encoded data of 5555512372".  However, the bars that follow "Together with the initial and terminal frame bars" represent, by their code, BAR 7 3 0 1 8 7 2 7 3 2 BAR.  How this comes from the data is not explained.  ???

thread_title: Example bars - inductive leap?

message: USPS' own website suggests that the Intelligent Mail barcode may be replacing the POSTNET barcode. I don't know enough about the background behind this to make any informed edits.  — Preceding unsigned comment added by Srtwin (talk • contribs) 20:04, 18 January 2011 (UTC)
thread_title: Is POSTNET being deprecated?

message: When was this invented and by whom ?  When was it adopted and disgarded ?  The article reads like it was written by 5 year old.
