Usps mailer requirements

The United States Postal Service (USPS) has specific requirements for mailers, which are outlined in the USPS Domestic Mail Manual (DMM) and other publications. Here are some key requirements:

  1. Addressing: Mailpieces must have a complete and accurate address, including the recipient's name, street address or post office box, city, state, and ZIP Code.
  2. Weight and Size: Mailpieces must meet specific weight and size requirements, which vary depending on the type of mailpiece and the service used. For example, First-Class Mail letters must weigh no more than 3.5 ounces and measure no more than 11.5 inches long, 6.125 inches high, and 0.25 inches thick.
  3. Shape and Orientation: Mailpieces must be rectangular in shape and have a flat surface. They must also be oriented in a way that allows them to be easily processed by automated machinery.
  4. Mailpiece Design: Mailpieces must be designed to be easily readable by automated sorting machines. This includes using a clear and legible font, avoiding complex graphics, and using a consistent layout.
  5. Barcodes: Many types of mailpieces require barcodes, such as the Intelligent Mail barcode (IMb) or the POSTNET barcode. These barcodes help the USPS sort and track mailpieces.
  6. Permit Numbers: Mailers who send large volumes of mail may need to obtain a permit number from the USPS. This number is required on the mailpiece and helps the USPS track and bill the mailer.
  7. Postage: Mailpieces must have the correct postage affixed. The USPS offers various postage options, including stamps, metered mail, and online postage.
  8. Content Restrictions: The USPS has specific restrictions on the types of content that can be sent through the mail. For example, mailpieces cannot contain hazardous materials, obscene or offensive content, or items that are prohibited by law.
  9. Mailpiece Preparation: Mailpieces must be prepared in a way that allows them to be easily sorted and processed by the USPS. This includes using a consistent layout, avoiding loose items, and using a sturdy envelope or package.
  10. Compliance with Regulations: Mailers must comply with all applicable USPS regulations, including those related to mailpiece design, addressing, and postage.
