What helps us most

A new price file: a Notice 123 file published on Postal Explorer, or a ruling of the Postal Regulatory Commission on the January 2027 prices.
A price or a zone that does not match what the Postal Service shows for the same weight and ZIP Codes, with both figures.
A rule we read wrong: quote the section of the Domestic Mail Manual that says otherwise.
Embedding the calculator on a store, school or library page: the code is on the embed page.

What we cannot do

We are not the Postal Service. We cannot track a package, file a claim, sell a label or change a delivery. The Postal Service handles all of these on usps.com and at its Post Offices.

Prices are read from the Postal Service price files, never estimated. They leave out pickup, special handling, hazardous material and any extra service you add at the counter. The January 17, 2027 prices are proposed and await review by the Postal Regulatory Commission.
