Quick Service Guide 201
September 14, 2015
Mailpieces are classified by shape and by the way they are prepared. These classifications are based on how efficiently mailpieces can be processed on Postal Service equipment. The Postal Service classifies letters and cards into one of three categories: machinable, nonmachinable, and automation. For the purposes of determining mailability or machinabilty, the length is the dimension parallel to the address as read (601.1.1.2).
Machinable Letters and Cards (201.1.0)
If you prepare your letters and cards so that they have an accurate address and can be processed on Postal Service equipment, your mail is “machinable” and eligible for “presort” prices. Machinable mailpieces must meet specific standards, including size, shape, and weight.
Maximum weight: First-Class Mail, machinable letters and Standard Mail machinable letters: 3.3 ounces, Periodicals letters: 3.5 ounces.
Nonmachinable Letters (201.2.0)
Maximum weight: First-Class Mail and Periodicals nonmachinable letters 3.5 ounces; Standard Mail nonmachinable letters; less than 16 ounces.
Automation Letters and Cards (201.3.0)
If your letter-size mailpiece is machinable and displays the correct delivery point barcode or Intelligent Mail barcode, you may qualify for lower, “automation” prices. A letter or card meets automation standards and qualifies for automation prices if it meets the specific addressing, barcoding, and design standards.
All letter-size reply cards and envelopes (Business Reply Mail, Courtesy Reply Mail, and meter reply mail) provided as enclosures must meet the physical standards for automation letters and cards in 201.3.17.
