USPS Mail Types: The 6 Classes of USPS Mail

USPS categorizes mail into six distinct classes, each offering varying service levels, postage prices, and pre-sort requirements. The class of mail you choose is typically determined by the content of your shipment and the required postage. If you're uncertain about which class of mail suits your specific mailing needs, refer to the matrix below to identify the class that best aligns with your priorities.

Priority mail (The Fastest Shipping Option)

Priority Mail Express is the fastest and most expedited shipping option USPS offers. It provides guaranteed overnight or 1-2-day delivery to most locations within the United States, including delivery on weekends and holidays. This service includes features such as tracking and coverage up to $100. Priority Mail Express is commonly used for time-sensitive documents, important letters, or valuable items that require secure and prompt delivery.

Priority Mail

Priority Mail is a fast and reliable shipping service that offers delivery within 1-3 business days throughout the United States. It includes features such as tracking and coverage up to $50. Priority Mail is suitable for larger packages, including heavier or bulkier items, and it provides excellent value for the speed and convenience it offers.

First-Class Mail

First-Class Mail is the most affordable option for sending lightweight items that do not require expedited delivery. It is commonly used for letters, postcards, and small packages weighing up to 13 ounces. Delivery time for First-Class Mail varies but generally takes 1-3 business days. This class of mail includes features such as tracking (for packages), and it offers competitive pricing for smaller, non-urgent shipments.

USPS Marketing Mail

Formerly known as Standard Mail or Bulk Mail, USPS Marketing Mail is designed for businesses and organizations that send advertising and promotional materials in bulk quantities. It offers discounted postage rates for larger volumes and can be used for both letters and flats (larger envelopes). Delivery time for USPS Marketing Mail varies, typically ranging from 2-9 business days. However, this class does not include tracking by default.

Periodicals

Periodicals class is specifically for publishers of newspapers and magazines. It offers discounted postage rates for the distribution of regular publications. Delivery time for Periodicals mail varies, depending on the frequency and destination of the publication. This class of mail is subject to specific requirements and eligibility criteria defined by USPS, and it offers tracking options for publishers.

Package Services/USPS Retail Ground

Package Services, also known as USPS Retail Ground, is a cost-effective option for sending large, heavy, or oversized packages that are not time-sensitive.
