What is a nonmachinable letter?

Introduction

In today’s world, the majority of communication takes place through electronic means, but traditional postal services still play a vital role in many aspects of daily life. While most letters and packages can be processed by machines, there are certain types of mail that require manual handling, and this can result in additional costs and delays. One such type of mail is known as nonmachinable letters, which have specific characteristics that make them unsuitable for automated processing. In this blog post, we will explore the definition of nonmachinable letters, their key features, and how to ensure your mail is processed as efficiently as possible.

Nonmachinable Letters: Definition and Characteristics

Nonmachinable letters are postal items that cannot be sorted and processed by machines due to their size, shape, or weight. The United States Postal Service (USPS) defines nonmachinable letters as items that are more than 1/4 inch thick, less than 3 1/2 inches high, less than 5 inches long, or weigh more than 1 ounce. Additionally, nonmachinable letters may have certain features that make them unsuitable for machine processing, such as clasps, buttons, or string closures.

There are several reasons why nonmachinable letters require manual handling. First, the machines used by postal services are designed to process items that have a standard size and shape, and anything outside of these parameters can cause jams and other issues. Second, nonmachinable letters often require special handling, such as being hand-cancelled or processed through a manual sorting machine. Finally, nonmachinable letters may require additional postage to cover the extra handling costs, which can be a significant expense for businesses and individuals.
