let me start by saying I didn't click on your links for what should be
obvious reasons.
If you're talking about orange barcodes on the back of a mailpiece
(non-address side), those are affixed by US sorting machines. they are
issued to a piece with a internal (USPS) # which temporarily (forget how
long; 10-30 days)links it to the address on the front. the address on
the front is either read automagically, by an optical character reader,
or a picture of the front is taken, sent by satellite to a remote
encoding center, read by a human, then the address linked to that
barcode & sent back. (sorry for the run-on sentence)

then any sorting machine in the country can read the orange barcode and
know the address to send it to. that's how it's "supposed" to work; YRMV

Is he correct, though? Seems to me if I were creating a serial number that
absolutely positively had to be unique network-wide, that a combination
of date stamp and machine number would be the way to do it. It would
have to be the machine, or the camera lens, that took the image, not
machines the piece was routed through after barcodes were applied.

not really sure what you're asking. the barcode is applied by the
facer/canceler if it's an original piece. he seemed to be speaking of a
piece from out-of-country, in which case the first sorting machine it
would come into contact with would either apply it, if it had that
capability, or rerouted to one that did

These serial numbers must be unique network-wide, that is, among all machines
in the post office sorting system that spray on bar codes according to
instructions from remote encoding. They must never be re-used. The easiest
way to do that is to create a number from a date stamp and machine number.
YOu'd probably include a sequence number and a definitely a check digit.

>the barcode is applied by the facer/canceler if it's an original piece.

That makes sense. What's an original piece, a letter that hasn't looped
back through the sorting process?

He seemed to know that it was a serial number of the image of the address
captured for remote encoding, though.

Canadian barcodes are fluorescent, but I don't know if they look like ours.
Is this because they don't use phosphor or fluorescent tags in stamps and
postage meter indicia and it's used to orient the mail?

you're getting into it deeper than I know (knew; retired now) about.
maybe a tech knows. AFAIK, those #s were temporary; time-limited. so
possibly they could be used again. I never knew how to read them w/naked eye

original piece=new piece; from the street or BMEU

again, above my scope of knowledge (and now that I'm gone, pretty much
above my level of GAS - heh)

So does this mean that the barcode does not provide information on where is was applied ? and only provides address info ? I'm confused. If you decipher the barcode, what does it tell you?

It just identifies that piece of mail and matches it to an entry in the
data base that has the info for that piece of mail. There might be a
location in the data base for that entry, but it is not in the barcode.

Then how are the ID numbers kept unique universe wide?

That makes a great deal of sense. I knew there had to be a time stamp in
there. I'm a little surprised that four digits are required for the
machine number.

Thanks for digging that up.

Interesting. MLOCRs still exist in mailing houses. What machine replaced it
in the post office plant environment?

Funny story, thanks.

10000, not 1000

Thanks. I'll look at it later.

I really appreciate the followups. Very interesting.
