Dmm 601 mailability meaning

A very specific question!

DMM 601 refers to the "Mailability" standard set by the United States Postal Service (USPS) for mailpieces. Specifically, DMM 601.1.1 defines "Mailability" as:

"Mailability refers to the ability of a mailpiece to be processed and delivered by the Postal Service. A mailpiece is considered mailable if it meets the applicable standards and requirements for size, shape, weight, and other physical characteristics, as well as any applicable regulations and restrictions."

In simpler terms, mailability refers to whether a piece of mail can be processed and delivered by the USPS. This includes factors such as:

  1. Size: The mailpiece must fit within the USPS's size guidelines.
  2. Shape: The mailpiece must have a rectangular shape with a flat surface.
  3. Weight: The mailpiece must not exceed the USPS's weight limits.
  4. Addressing: The mailpiece must have a valid address and be properly labeled.
  5. Content: The mailpiece must not contain prohibited or restricted items, such as hazardous materials or certain types of mail.

If a mailpiece meets these criteria, it is considered mailable and can be processed and delivered by the USPS. If it does not meet these criteria, it may be considered non-mailable and may not be accepted by the USPS.
