What qualifies for first class mail
In the United States, First-Class Mail is a type of mail service offered by the United States Postal Service (USPS) that provides fast and reliable delivery of letters, cards, and other lightweight items. To qualify for First-Class Mail, your mailpiece must meet certain requirements. Here are the general guidelines:
- Weight: First-Class Mail is limited to 13 ounces (369 grams) or less. If your mailpiece weighs more than 13 ounces, you'll need to use a different mail service, such as Priority Mail.
- Size: The maximum size for a First-Class Mail letter is 11.5 inches (29.2 cm) long, 6.125 inches (15.6 cm) wide, and 0.25 inches (0.64 cm) thick. For larger items, you'll need to use a Flat Rate envelope or a Priority Mail box.
- Shape: First-Class Mail letters can be rectangular, square, or irregularly shaped, as long as they fit within the size limits.
- Content: First-Class Mail is for sending letters, cards, and other lightweight items, such as:
- Letters (including handwritten or typed correspondence)
- Postcards
- Greeting cards
- Photographs
- Printed matter (e.g., brochures, catalogs, newsletters)
- Small packages (e.g., jewelry, coins, small toys)
- Addressing: Your mailpiece must have a valid, complete address, including:
- Recipient's name
- Street address or post office box number
- City, state, and ZIP code
- Country (if sending internationally)
- Postage: You must affix the correct postage, which is based on the weight and size of your mailpiece. You can use a Forever Stamp or a First-Class Mail stamp, which is valid for 1 ounce or less.
- Mailing: Your mailpiece must be properly prepared for mailing, including:
- Using a sturdy envelope or package
- Securing the contents with tape or a closure
- Avoiding excessive bulk or irregular shapes
If your mailpiece meets these requirements, you can send it as First-Class Mail. Keep in mind that the USPS has specific regulations and restrictions for certain types of mail, such as hazardous materials, perishable items, or items that require special handling.
