What Is Postal Code

A postal code is a system consisting of postal codes that have been used by the United States postal service since 1963. ZIP is an acronym that stands for Zone Improvement Plan. When senders use the postal address code, which consists of five digits, the mail is sent more effectively and quickly, hence the name. The format of the main postal code is composed of five digits. In 1983, ‘ZIP + 4′ an extended code was introduced; presented the five digits, a dash and four other digits that were added to the orders to locate the destination more precisely. Originally, the United States postal service registered the term “postal code” as a service mark, but has since expired.

Postal code history

The context of the postal codes started with the zone numbers or the postal district. In 1943, the implementation of postal codes for some large cities was carried out by the US Post Office Department (USPOD). During the early 1960s, a more strategic system was required that led to the introduction of non-numeric five-digit postal codes on July 1, 1963, throughout the country. In October 1, 1963, publication 59 was issued by the US Post Office Department, with the abbreviations used with the zip code. It is a list of two letters of a state abbreviation written in capital letters. However, it had previously been suggested that the capitalization of abbreviations would be between two and five letters. THE’ idea of ​​a two-letter standard on “Publication 59” was based on a maximum position line 23 since it was universally accepted as a more efficient line capacity basis for primary addressing systems.

The abbreviation of two letters will then be followed by a long city name that is also supplemented with a status of several letters, for example “Sacramento, Calif” will be combined with the postal code of the area. However, these abbreviations have not changed except in 1969, when the Canadian postal administration requested that the abbreviation for Nebraska be changed to NE from NB so that people could stop confusing it with the Canadian province of New Brunswick. it was based on a maximum position line 23 since it was universally accepted as a more efficient line capacity base for primary addressing systems.

 

In 1944, Robert Moon, who is considered the inventor of the CAP, presented the idea while working as a postal inspector. He is given the first three digits that describe the center, also known as the center of the sectional center (SCF). The SCF is the one that orders the mail with the first three digits in its zip codes in all post offices before being ordered for the last two digits and then sent to the corresponding offices. However, sectional centers are not accessible to the public and do not deliver mail, with most employees working the night shift. In the afternoon, e-mails collected in post offices are then sent to the specified SCF and ordered overnight. The last two digits in the larger cities corresponded to the old postal area number.

A ZIP code is usually interpreted in an Intelligent Mail barcode that is printed on the piece of mail, making it easier for automated machines to classify mail. The sender can print a barcode, but it is advised to allow the post office to do so when it is processing the piece. The post office uses OCR technology, although sometimes it may be required of a human being to read and enter the address. At the postage, customers who send wholesale mail usually receive a discount in the event that they pre-order the mail or print the barcode.

The mailing lists must be standardized with the updated versions of the code accuracy support system (CASS), an accredited software that not only verifies, but it also adds the correct ZIP plus four Code plus two additional digits that represent the specific delivery point. The mail should be ordered in a particular scheme, a code 11 with at least 150 and accompanied by a verification documentation. The PAVE certified software adopts these measures, including the printing of the address labels for the bar code and the tags of the tray or bag. Thus, each of the postal points in the states comprises a number of digits 12. including printing of address labels for the barcode and tray or bag tags. Thus, each of the postal points in the states comprises a number of digits 12. including printing of address labels for the barcode and tray or bag tags. Thus, each of the postal points in the states comprises a number of digits 12.

Structure

In the United States, delivery points are designated by postal codes and overseas stations, including territories for its armed forces. The Republic of the Marshall Islands, the Republic of Palau and the independent nations of the Federated States of Micronesia each have postal codes integrated into the US postal system which is managed by a free association agreement. Similarly, mail that is sent abroad to any US diplomatic mission is often handled as if it were destined for an address in Washington, DC. The diplomatic mail includes a four-digit diplomatic mail number, which is not only used as a building number, but also the city where the embassy is located, and is combined with the place of the term, which forms the name of the street .

ZIP codes are generally labeled with numbers that begin with the first digit representing a specific group of US states. Both the second and third digits represent an area in that group, therefore the alphabetical order comes after the numerical order. Although the idea of ​​postal codes was meant for systematic mailing, there are some circumstances in which postal codes could cross state borders, a good example is military structures.
