Up to date , easy to understand
USPS® postage prices


The Postal Service’s Notice 123 is a summary of all the rates you need to know. The real question is “but do I really need to know all the rates?”. This is our single page summary guide. It is not everything, but probably gets you 90% of what you will need of current First-Class rates without digging through needless detail.

-> Priority Mail Express® Flat Rate Envelopes + Boxes

Pricing is typically around $25.00 ($24.70 to $25.40) and currently represents the fastest service that the USPS® offers; however, it’s still only guaranteed overnight for (to and from) urban areas, and the service takes 2 days for non-urban (rural) delivery.

-> Priority Mail® Flat Rate Envelopes + Boxes

Priority Mail flat-rate pricing is attractive because, regardless of weight, if you can seal it, you can ship it. Service shipping timeframes = 1 to 4 days for confirmed and tracked delivery. Shipping materials available at the Post Office or you can order them online at the USPS® store. Here are the most popular flat-rate sizes and prices:

-> EDDM® (Every Door Direct Mail®): 17.8¢
-> First-Class Pre-sorted Letters (Commercial Rates)

These are First-Class Mail rates that you can expect to pay if you are mailing at least 500 letters under your own postal permit. Unless you have the software to attain automation rates, you’re probably looking at $.458 per letter mailed. Your local post office is not supposed to take more than 4 trays of mail under permit and will likely direct you to the regional BMEU, or, Bulk Mail Entry Unit if it doesn’t have a BMEU window at its location)

Mailpiece Weight 5-Digit Automation AADC Automation Mixed AADC Automation Presorted Only (no automation)
1 oz – 3.5 oz 37.8¢ 40.8¢ 42.4¢ 45.8¢
-> Marketing Mail (a.k.a. “Bulk Rate” or “Standard Mail”) Presorted Letters (Commercial Rates)

These are Bulk Mail rates that you can expect to pay if you are mailing at least 200 letters under your own postal permit. Once big difference is that you get rewarded (or not) for the destination of your addresses (making preparation more of a hassle, too). If you want “everyone to get the letter” (saturation both presorted and automation barcode), here are your rates:

-> COMMERCIAL BULK MAIL AT SATURATION RATES
Mailpiece Weight Local Saturation ("SCF Discount") Out-of-the-Area Saturation
1 oz - 4 oz 15.8¢ 18.6¢

1 oz - 4 oz No 25.1¢ 27.4¢ 28.7¢ 28.7¢ - 30¢

Unless you have the software to attain barcode (automation) rates, you’re probably looking at 25.6 cents per locally mailed presorted only letter or 28.7 to 30 cents per out-of-area mailed presorted only letter.

Both commercial and non-profit mailings, your local post office is generally not encouraged to take more than 4 trays of bulk-rate mail (if they accept bulk mail at all!) under permit and will likely direct you to the regional BMEU, or, Bulk Mail Entry Unit if there is not a bulk mail “window” at its retail location.
