Priority Mail Express

Minimum Weight: None

Maximum Weight: 70 pounds

Priority Mail Express is the fastest mail service offered by the Postal Service. It provides guaranteed 1-Day or 2-Day expedited service by 3 p.m. for any mailable matter and includes $100 of insurance coverage. Priority Mail Express delivery is offered 365 days a year in many locations.

If available at the destination location, delivery by 10:30 a.m. or Sunday or holiday delivery may be purchased at an additional charge.

Priority Mail Express packaging supplies (envelopes, boxes, tubes) are available at no cost from your local Post Office. If getting your mail there overnight is your highest priority, then Priority Mail Express is the best choice. Many businesses use First-Class Mail, Priority Mail, or Standard Mail for regular mailings and Priority Mail Express for important business documents, like contracts and sales orders.

Priority Mail Express prices are based on the weight of the piece, and how far the piece travels except when USPS-provided Priority Mail Express Flat Rate packaging is being used.

Priority Mail Express Flat Rate packaging: Use for anything mailed in the special Flat Rate Envelopes or Boxes provided by the USPS, regardless of weight or domestic destination (70 pound weight limit).

Lower commercial prices are available for Priority Mail Express items that meet eligibility standards and must contain an Intelligent Mail barcode or you could be charged a non-compliance fee.

TIP
--When using USPS-provided packaging, you will be charged for the class of mail printed on the packaging.
