How Long Does USPS Flat Rate Take to Arrive?

When deciding what shipping option to choose, the delivery time is a very important part of the process. USPS offers both flat rate and first-class mail shipping options. How long does USPS flat rate take? USPS Priority Mail and USPS Priority Express are the two fastest methods for shipping items through the service. USPS Priority Mail arrives within one to three days, depending on the destination, while USPS Priority Express arrives within one day.

USPS Priority Mail Two-Day

This is the most cost effective flat rate shipping option provided by the USPS. Priority Mail Two-Day is great for sending and receiving packages within a few days, without having to pay a premium price. It is important to read up on the different flat rate envelopes and boxes available with USPS. The envelopes come with one flat rate price, while the different sized boxes have their own price points.

Delivery Times

When sending packages through USPS Priority Mail 2-Day, senders receive a tracking number that allows them to track the progress of their shipment. How long does USPS flat rate take? The exact time and date of delivery varies based on the locations of the sender and receiver. For example, if the sender and receiver are in the same city or state, delivery times are likely to be within 24 hours. In contrast, sending packages from California to New York may take the full three days. Likewise, USPS First-Class Mail takes anywhere from three to seven days before arriving at the destination.

USPS Priority Mail Express

Priority Mail Express is a one-day service that allows individuals to send and receive time sensitive envelopes and packages overnight. This service comes with a premium price, making it much more expensive than the Priority Mail Two-Day flat rate options. Unless you really need to get a package to someone overnight, it is probably best to stick with Priority Mail Two-Day. However, for those who are in a rush for business or personal documents and packages, this shipping option is still less expensive than other companies’ offerings.

USPS Flat Rate Packages

One of the advantages of flat rate shipping is the fact that you do not need to get your own envelope or box. Simply arrive at your local post office and pick up the appropriate envelope or box for your shipment. Senders have the option of setting up their package at the post office, or taking the envelope or box home to make sure everything fits inside.

Online Tools

The USPS website makes it very easy for customers to understand the different flat rate options available to them. By entering the sender’s and receiver’s zip codes, the date you send the item and the envelope or package size, USPS displays information about the various flat rate shipping times, costs and other relevant information. This can help you make a decision between USPS Priority Mail Two-Day and USPS Priority Mail Express. In a small percentage of cases, it may even be financially prudent to use the USPS First-Class Mail option, especially for delivering items within the same city.
