USPS First Class Mail

What is First-Class Mail?

First Class Mail is the most popular and economical way to send items through USPS. You can send standard postcards, letters and large envelopes and small packages up to 13 ounces using First Class Mail. If the letter or package is over 13 ounces, you must upgrade the mail class to Priority Mail.

While there are no guaranteed delivery times for First Class Mail, letters or packages typically take two to three days to arrive at their final destination in the U.S.

How Does First Class Mail Work?

After you've sealed and addressed your item, you must check its dimensions before trying to send it through First Class Mail. USPS has size restrictions for letters and packages sent with this service as shown below:

Mail Item Width Length Weight First Class
Rate - 1 oz.
Post Card 5.00" to 6.00" 3.50" to 4.25" Up to 3.50 oz $0.28
Letter 5.00" to 11.50" 3.50" to 6.125" Up to 3.50 oz $0.44
Large Flat Envelope 12.00" max 15.00" max Up to 13.00 oz $0.88
Small Packages Any size Any size Up to 13.00 oz $1.22


You can attach stamps to large envelopes and small packages to be sent through First Class Mail as long as you've met USPS's weight restrictions. It costs $0.88 to send the first ounce of a large envelope and $1.22 for the first ounce of a small package. Additional ounces cost $0.17 each. Letters that can't be sent through the Post Office's automated machines have a $0.20 postage surcharge.

You can purchase additional services for your First Class Mail item. Certified Mail is available for all pieces of mail sent through First Class Mail. Delivery Confirmation and Signature Confirmation only are available for small packages sent through First Class Mail. If you are sending a post card, Registered Mail, Return Receipt, insurance, restricted delivery and COD are not available.
