What Is First-Class Mail?
First-Class Mail is the USPS's most popular and economical service. That's not all that makes it great! First-Class Mail delivers anywhere in the United States in 1-3 days, for a low cost.
You are probably already familiar with sending letters via First-Class Mail, but did you know you can also send postcards and large flat envelopes? You can! Each item has different size and weight specifications outlined in the handy chart below.
These details are important to reference because, if your letter is too big or too heavy, it might not be delivered and it could be returned delaying important communications and costing you more time and money.
How much is First-Class Postage?
The most common item sent via First-Class Mail is your standard 1-ounce letter which requires one stamp worth 55 cents or 50 cents if you use a postage meter. If you are sending mail that is heavier than 1 oz., like multi-page documents or wedding invitations, you will be charged .15 cents for each additional ounce and need to apply additional postage.
The last thing you want to do is underpay and have your important letter returned. The best way to avoid this is to take heavier letters to the Post Office™ or use a postage meter to stamp them at home or in the office. Postage meters come equipped with a scale so you can weigh your mail so you never under or overpay for postage.
Prices also vary depending on your mail item.
