How We Keep This Accurate
Every rate on this page is pulled from a verified fact library maintained by Postmarkr. Each fact is traced to an official USPS source — primarily USPS Notice 123, the Domestic Mail Manual, and official USPS service pages.
Every fact records its effective date, last verification date, and the exact source location (down to the section and line number). Automated CI checks flag any rate fact that hasn't been re-verified within 60 days of a USPS rate cycle change.
USPS typically updates rates in January and July each year. We re-verify all rates within weeks of each change. If you spot an error, please let us know.
