Letter Plate vs. Letterbox: Understanding the difference

When it comes to mail delivery, we often use the terms "letter plate" and "letterbox" interchangeably, assuming they refer to the same thing.


However, these two terms actually describe distinct components of the mail delivery system.


In this blog post, we will delve into the key differences between a letter plate and a letterbox, shedding light on their unique functions and characteristics.

Letter plates


Letter plates are the plate that sit on the external part of the door to cover an aperture. They are available in polished brass, stainless brass, polished chrome, satin chrome and many other finishes. Letter plates work in conjunction with Inner tidies/flaps.


What are Letter Plates?

Letter plates are an essential piece of door furniture as they allow mail and letters to be safely posted through your front door.


They are an item that no front door should be without! The letter plate or letterbox should match the style of the other pieces of front door furniture on display.


Unfortunately, there is no such thing as a standard size letter plate, so in some cases where an aperture has already been cut from the door, a bespoke letterbox can be manufactured to fit to size.

Here are some key features of a letter plate:


Location: Letter plates are typically found on external doors, particularly those of houses, apartment buildings, and business establishments.


Purpose: The primary purpose of a letter plate is to facilitate the secure delivery of mail without the need for the recipient to open the door. Postal workers or delivery personnel can simply slide letters and small parcels through the slot, ensuring that the mail is protected from theft and weather.


Size: Letter plates are generally narrow, rectangular openings designed to accommodate standard-sized envelopes and small packages. They are not large enough to receive larger items or bulky parcels.

A letterbox or postal box, on the other hand, is a receptacle or container used for the collection and temporary storage of incoming mail until it is retrieved by the recipient. Here are some key features of a letterbox:


Location: Letterboxes are typically situated outside a building, often near the entrance or at the end of a driveway. They can also be found in communal areas of apartment complexes.


Purpose: The primary purpose of a letterbox is to provide a designated location for mail delivery, ensuring that the mail is organized and protected until the recipient retrieves it. It serves as a secure repository for incoming mail.


Size: Letterboxes come in various sizes to accommodate different volumes of mail. Some are small and designed for individual households, while others are larger and intended for shared use in apartment buildings or business complexes.

In summary, while the terms "letter plate" and "letterbox" may seem similar, they refer to distinct elements of the mail delivery process.


A letter plate is an opening in a door or wall that allows for direct mail delivery into a building, while a letterbox is a container located outside a building for the collection and secure storage of incoming mail.


Understanding the differences between these two components can help ensure efficient and secure mail handling for both residential and commercial properties.
