Post Codes were introduced in South Africa on 8 October 1973, with the introduction of automated sorting.
South African post codes consist of four digits. Mail may be delivered either to the physical address or to a PO Box, particularly in rural areas where no street delivery is available. In addition, many large organisations may use Private Bag addresses, with mail dispatched to the holder by a mail contractor.
In the case of cities and large towns, however, the last two digits of the postcode indicate the mode of delivery.The digits "01" indicate a street address and "00" a PO Box or Private Bag address, with addresses in Port Elizabeth, for example, using the following format:
300 Kempston Road Port Elizabeth 6001
PO Box 1840 Port Elizabeth 6000
In Pretoria, however, a different format is used, with "02" indicating a street address, and "01" indicating a PO Box or Private Bag address.
370 Church Street Pretoria 0002
PO Box 427 Pretoria 0001
A feature of South African postal addresses, also common to Australia, is that it is only necessary to include the suburb, not the city, for example, in the case of Yeoville in Johannesburg:
43 Cavendish Road Yeoville 2198
The South African post code system was previously used in Namibia, then "South West Africa", including the enclave of Walvis Bay, which remained part of South Africa until 1994. It was allocated the number range 9000–9299.
Following independence, use of the South African postcode system was discontinued.
Post code boundaries do not follow provincial borders exactly, especially since the re–organisation of provinces in 1994.

A ZIP Code is a postal code used by the United States Postal Service (USPS). Introduced in 1963, the basic format consists of five digits.

Postal codes used in the United Kingdom are known as postcodes. They are alphanumeric and were adopted nationally between 11 October 1959 and 1974, having been devised by the General Post Office. A full postcode is known as a "postcode unit" and designates an area with a number of addresses or a single major delivery point.
A Canadian postal code is a six-character string that forms part of a postal address in Canada. Like British, Irish and Dutch postcodes, Canada's postal codes are alphanumeric. They are in the format A1A 1A1, where A is a letter and 1 is a digit, with a space separating the third and fourth characters.

Postcodes in New Zealand consist of four digits, the first two of which specify the area, the third the type of delivery, and the last the specific lobby, RD number, or suburb. The present postcode system was introduced in New Zealand in June 2006, which, unlike the previous system, applies to all items of mail with effect from June 2008. In October 2008, New Zealand Post launched a 'remember your postcode' campaign, offering a NZ$10,000 prize for remembering a postcode.
Postal codes were introduced in France in 1964, when La Poste introduced automated sorting. They were updated to use the current 5 digit system in 1972.
In a postal system, a delivery point is a single mailbox or other place at which mail is delivered. It differs from a street address, in that each address may have several delivery points, such as an apartment, office department, or other room. Such buildings are often called multiple-dwelling units (MDUs) by the USPS.
A post office box is a uniquely addressable lockable box located on the premises of a post office station.
An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail.

Private mail bag addresses are often used in countries in Africa where there may be no street delivery service.
Postcodes are used in Australia to more efficiently sort and route mail within the Australian postal system. Postcodes in Australia have four digits and are placed at the end of the Australian address. Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department and are now managed by Australia Post, and are published in booklets available from post offices or online from the Australia Post website.

The second and third digits specify a particular smaller region, and the last two are the number of a postal delivery branch.
A mail pouch or mailpouch is a container for mail, designed to transport first-class, registered mail, domestic mail and military mail. It usually has a drawstring, and is made of a stronger material than mail sacks and is designed to lock at the top with a mechanism system consisting of special closely spaced eyelets and a strong strap to secure the top where access into the bag is closed off and locked, where a mail sack does not have these features.
A mail bag or mailbag is a generic term for a type of bag used for collecting, carrying, categorizing, and classifying different types of postal material, depending on its priority, destination, and method of transport. It is oftentimes used by a post office system in transporting these different grades of mail. The mailbag is carried by some means of transporting like a mail carrier, animal, or a mobile post office. Letters and printed material delivered by mail in the seventeen-hundreds were carried by horse in a saddle bag. There are several different types of mailbags for different purposes (e.g., transporting mail to and from post offices, delivering mail to businesses and homes. These different styles of mailbags depend on its size and purpose. It can range from "a large bag used for transporting mail on a truck, plane, etc." to a simple "postbag" used by a mail carrier to deliver mail.
