United States 
POSTAL RATES

Contributed by Mike Ludeman

This page contains an archive of the last few decades of the USPS postal rate changes in the form of their ‘Notice 123’ publication. The most recent version is available on the USPS website but they do not maintain an archive of previous rate notices there. For even earlier postal rates please refer to Tony Wawrukiewicz's excellent Domestic and International Rates books on this topic.
If you have any Notice 123 versions published after 1995, that are not represented here and would like to see them listed, please use the contact form and let me know.
