How USPS Shipping by Zip Code Works

USPS shipping rates are determined by several factors, including the origin and destination zip codes, package size and weight, and the type of service selected. The USPS uses a complex pricing algorithm that takes all these factors into account to calculate the final shipping cost.

Our calculator uses USPS's published rate tables and algorithms to provide accurate estimates. The calculator considers:

• Distance between zip codes
• Package dimensions and weight
• Package type (letter, flat, or package)
• USPS service type (First Class, Priority, Express, etc.)

Factors Affecting Shipping Costs

Several factors influence USPS shipping costs:

Distance

The distance between the origin and destination zip codes is a major factor in shipping costs. Packages sent longer distances typically cost more than those sent shorter distances.

Package Size and Weight

Larger and heavier packages generally cost more to ship. USPS charges based on both the dimensions and weight of the package.

Package Type

USPS offers different shipping options for different package types:

• Letters: For small, lightweight items
• Flat Rate: For standard-sized packages
• Packages: For larger, heavier items

Service Type

USPS offers several service types with different delivery times and costs:

• First Class: Standard service for letters and small packages
• Priority Mail: Faster delivery than First Class
• Express Mail: Fastest delivery option
