Free USPS Postage Rate Widget for Your Blog
USPS changes First-Class rates most Julys. Every postage table on the web quietly goes wrong that morning, and nothing tells the person who wrote it. This one updates itself.

What it does, and what it doesn't
- Re-bases itself on the USPS effective date, so the July increase lands on your page without you touching it.
- About 1.8 KB, loads asynchronously, and renders nothing until the rest of your page is done.
- No cookies, no tracking pixel, no analytics — it reads nothing about your visitors.
- The table carries one small “ShipNote” credit linking back to our stamp calculator. That is the only string attached.
Need the arithmetic, not just the rates?
The stamp calculator works out how many stamps a specific card needs — by size, weight, and envelope shape — and what a whole batch will cost.
