How long does the postal service take to deliver a package?

The United States Postal Service delivery times vary depending on the origin and destination cities as well as the type of delivery requested, such as priority or overnight delivery. For example, Priority Mail Express offers guaranteed overnight delivery.

Priority mail and First Class mail are delivered within 1 to 3 business days, while Standard postal delivery can take up to 8 business days. Except for First Class mail, the USPS offers tracking for letters and packages so senders know where their mail is located until it reaches the delivery destination. Even when sending a package through Priority Mail Express, delivery time might exceed the estimate depending on the location of the destination.
