USPS is committed to giving you the tools you need for an easy and seamless shipping experience.We've provided some tips below to help you understand the best practices for improving your shipping procedures and how to calculate postage correctly, so you're not overpaying or underpaying.
How to Calculate Postage Correctly
Weigh your item and round up
USPS® rounds up to either the next pound (lb) or ounce (oz).例如，如果您的包裹重量为 3 磅 5 盎司，则它将按 4 磅计费。If you have an item for shipping by First-Class Package® service that weighs 7.3 oz, it must be charged at the 8 oz-rate.该原则适用所有邮件级别 - 国内和国际邮件。
Select the right mail class
For example, First-Class Package® service can only be used for packages under 15.999 oz; anything over the weight limit must be shipped with Priority Mail® service.And domestic Regional Rate Boxes A and B have 15 and 20 lbs limits respectively.
Measure your package
Measure the length, width, and height of the package.Dimensional (DIM) weight may also apply to your packaging.DIM weight is determined by multiplying a package's length, width, and height and applying a volumetric divisor.1 DIM weight = (L X W X H)/194.
Label your package correctly
USPS provides a wide range of shipping options to help you meet your mailing needs.请确认您正在使用的标签与包裹相匹配。例如，如果您正在使用统一邮资包装盒，则您也应使用统一邮资标签。Or anything shipped in Priority Mail® packaging requires a Priority Mail label.Also, ensure you place the label on the long side of the box.标签不可覆盖在端部或边缘，并且所有条形码都应朝向相同的方向。
Double check the zone
If you are using PC Postage® software, verify that the origin address (or "sent from") is up to date before printing the label.Please note, USPS charges by zones.To get a zone chart for your ZIP Code™ use the Postal Calculator.计算价格
