Save Time & Money

  1. Calculate postage correctly.

    Make sure you're not underpaying or overpaying on postage. When a package is sent with incorrect postage, it may delay its delivery and the recipient can be charged for postage due.

    • Round up on weights. USPS® rounds up to either the next pound (lb) or ounce (oz). For example, if your package weighs 3 lbs 5 oz, it would be charged at the 4 lb-rate. If you have a First-Class Package Service-Retail™ that weighs 7.3 oz, it must be charged at the 8 oz-rate. This applies to all mail classes—domestic and international.
    • Verify the mail class. For example, First-Class Package Service-Commercial™ can only be used for packages under 15.999 oz when creating a label through a PC Postage vendor, anything over the weight limit must be shipped with Priority Mail® service. And Regional Rate Boxes A and B have 15 and 20 lbs limits respectively.
    • Check the dimensions. Dimensional weight may apply to your packaging. This may apply for Priority Mail packages with volumes over a cubic foot and traveling 5 zones or more. Enter your package’s dimensions to ensure you are accurately charged for Dim Weight. Learn About Dimensional Weight.
    • Match the label to the packaging. USPS® provides a wide range of shipping options to help you meet your mailing needs. Make sure that the label you are using matches the packaging. For example, if you are using a Flat Rate box, you should also use a Flat Rate label. Or anything shipped in Priority Mail® packaging requires a Priority Mail label.
    • Place the label on the long side of the box. Labels should not wrap over the ends or edges and all barcodes should face up in the same direction.
    • Double check the zone. If you are using PC Postage software, verify that the origin address is up to date before printing the label. Please note USPS charges for zones not ZIP Codes™, to get a zone chart for your ZIP Code use the Postal Calculator.

  5. Avoid dimensional weight costs.

    Domestic Dimensional Weight

    Dimensional (DIM) weight pricing calculates shipping costs based on the space a package takes up as well as its weight. Compare the calculated DIM weight and the actual package weight. Your shipping postage is charged at the higher weight.

    • USPS® only applies domestic DIM weight pricing to domestic Priority Mail® packages larger than a cubic foot that are shipped to zones 5–9.
    • The USPS domestic DIM weight formula is:
             Length x Width x Height ÷ 194
