What is machinable mail

Machinable mail refers to mailpieces that are designed to be processed by automated machinery, such as automated processing machines (APMs) and automated package processing machines (APPMs), at the United States Postal Service (USPS).

To be considered machinable, a mailpiece must meet specific requirements, including:

1. Size: The mailpiece must be rectangular in shape and have a length of at least 3.5 inches and a width of at least 6.125 inches.
2. Weight: The mailpiece must weigh no more than 13 ounces.
3. Thickness: The mailpiece must be no thicker than 0.75 inches.
4. Edge: The mailpiece must have a smooth, even edge that is free of rough or jagged edges.
5. Surface: The mailpiece must have a smooth, even surface that is free of wrinkles, creases, or other irregularities.
6. Adhesive: The mailpiece must have a smooth, even adhesive surface that is free of wrinkles, creases, or other irregularities.
7. Labeling: The mailpiece must have a clear, legible address label that is securely attached to the mailpiece.

Machinable mailpieces are typically processed at a higher speed and with greater efficiency than non-machinable mailpieces, which are processed manually. Machinable mailpieces are also subject to lower postage rates than non-machinable mailpieces.

Examples of machinable mailpieces include:

• Standard envelopes
• Postcards
• Catalogs
• Brochures
• Flyers
• Booklets
• Small packages

Examples of non-machinable mailpieces include:

• Large or irregularly shaped packages
• Mailpieces with unusual shapes or sizes
• Mailpieces with rough or jagged edges
• Mailpieces with wrinkles, creases, or other irregularities
• Mailpieces with handwritten or irregularly printed addresses

It's worth noting that while machinable mailpieces are processed more efficiently and at a lower cost, they may not be suitable for all types of mail. For example, mailpieces that are fragile, valuable, or require special handling may not be suitable for machinable processing.
