[can.general] Canada Post codes

jmlang@water.UUCP (12/03/86)

With the Christmas rush coming, Canada Post has provided an incentive
to use an efficient way to sort automatically Christmas cards by 
lowering the postage for those that are mailed with special
enveloppes.  I think this is a good idea.

The scheme used is to fill little boxes corresponding to the postal
code of the recipient.  I also noticed that on some business letters
(or junk mail or bills or ...), there is an encoding that is 
very similar.  Also, some letters get some fluorescent postal code
encoding. Have you noticed the 4 vertical bars next to the area for
the stamps on reply enveloppes for bills? Apparently, these indicate 
that the letter may contain money and thus get priority in the sorting
process (and runs havoc for people who count on their check to take
x days to reach the creditor).  Do business have to pay to 
Canada Post for this priviledge of getting their mail faster than
we do? Looks to me like another class of mail...

I am also curious of any possible codes that the sorting machines
are able to distinguish.
