Bar codes for mailing

[Jim Hurley]

I'm trying to cut the costs for mailing our neighborhood newsletter. 
It goes to mostly to just one 5 digit zip code. So pretty simple.

So the first thing is to get the 9 digit zip code. I've writen a 
program to download the 9 digit zip for a given set of address from 
the USPO web site. So far the program works for most address; just a 
few that the USPO doesn't recognize.

  It takes about 15 minutes to run about 360 names. It has to read one 
address at time. I don't know how much of this time is a result of my 
band width or the delay from the web site. I am constrained to a 58K 
modem.

Of course the ultimate objective is to generate bar code. I've found 
a site to get the bar code font.

Does anyone know if the bar code needs to contain something besides 
the code for the 9 digit zip code?
