USPS Express Mail
What is Express Mail?
USPS Express Mail is a guaranteed way to send documents and packages to a destination overnight or in one to two days on any day of the year, including Sundays and holidays. If the US Postal Service doesn't deliver your package on time, they will refund the full delivery cost to you. Items under 70 pounds can be sent through Express Mail to any address in the United States. Express Mail comes with up to $100 in insurance and delivery tracking for free.
USPS is the only overnight shipping carrier that is allowed to deliver packages to a P.O. Box address. Other carriers, such as UPS and FedEx, are not able to deliver packages to mailboxes in the Post Office.
USPS uses zone-based pricing for Express Mail. There are 8 zones in the United States. Prices are based on the distance from the original package location to the delivery destination. Prices start at $13.05 through USPS and $12.40 for Stamps.com customers. Additional fees apply for packages that must arrive on Sundays or holidays.
Preparing Packages for Express Mail
Express Mail must be marked with pre-printed stickers or boxes from USPS to ensure that they arrive at their final destination quickly. USPS offers free Express Mail Flat Rate envelopes and boxes which bear the Express Mail symbols, which you can order for free through the Stamps.com Store. You also can order free Express Mail stickers, which you can place on your own packaging.
If using your own packaging, the USPS requires you to fill out Form 11-B, which is an Express Mail carbon-copy address form. After you fill it out, stick it to the center of the top side of your package. The postage label should be placed in the upper right corner of that side.
You can legally send small envelopes through Express Mail, but it's not recommended because the required form is often larger than the envelope and can become separated during delivery. Instead, drop the little letter into a larger pre-printed Express Mail envelope to ensure that your item arrives safely.
