First ClassMail (United States)

A standard letter that weighs less than one ounce requires only one postage stamp to send it. This is known as the Basic Rate and can be purchased at any USPS location nationwide*. 

ForeverMail (United States)

A Forever Stamp is a special type of stamp that covers the cost of up to 2 ounces of mailing. This makes it a perfect choice for letters, greeting cards and other items weighing less than one ounce. 

In 2020, a Forever Stamp costs 55 cents to mail a letter that weighs under one ounce, and it also costs an additional 15 cents for each ounce of extra postage. Using Forever Stamps saves you money on postage and helps protect the environment by using recycled stamps. 

You can find out how many Forever Stamps you need by visiting the USPS website and entering your package dimensions in their online postage calculator. You can then select the type of postage you are sending and adjust the price according to your destination and a number of other factors until you reach a final dollar value. 

InternationalMail (Worldwide)

In some countries, shipping prices vary based on the size and weight of your package. If you are unsure of how much your package weighs, you can always take it to a retail postage scale to get an accurate measurement. 

The postal service has a website called Click & Ship where you can get your package weighed to calculate the postage amount that you will need for your letter. You can then print a postage label and get your package shipped to its destination. 

Depending on where you live, you may need to register your package before it can be sent out. Registration fees vary by region, county and zip code. You can also purchase additional postage tickets for longer distances or if you want your package delivered faster than normal. 

To register your package, simply complete the online form, include a valid proof of address and pay any applicable registration fees. This will ensure that your package can be delivered to its intended recipient as quickly and safely as possible. 

BulkMail (Worldwide)

If you’re planning on mailing a large amount of mail, you’ll need to factor in the cost of bulk stamps. These stamps are sold in packages of different denominations and are usually affixed by postal clerks. 

Once you know how many stamps you need, you can purchase them from the post office or at your local retail store. The post office will also have a stamp calculator for you to use, so you can easily estimate the amount of postage that you will need.
