United States Postal Code The United States Postal Code (ZIP Code) is a postal code used by the United States Postal Service (United States Postal Service

USPS). It is usually written in capital letters as ZIP. ZIP is the abbreviation of Zone Improvement Plan, which implies that mail can be delivered to its destination more efficiently and quickly. The most basic ZIP number consists of five numbers, with four numbers later added to allow the mail to be delivered to its destination more precisely. The ZIP number after the added number is called "ZIP+4". The ZIP number was once registered as a trademark by the U.S. Postal Service, but its registration has expired. Since 1943, the United States has implemented postal divisions for postal services in some large cities, such as: (In order to show the actual application of ZIP numbers in the United States, the following address examples use the sorting method of English addresses, that is, the order is reversed from the Chinese addresses) Example A1: John. Smith 3256 Avenue 16 Minneapolis, Minnesota Example A2: Wikimedia Foundation 200 Second Avenue, South #358 St. Petersburg 1, Florida Example A1 The "16" and Example A2 "1" is the zip code within the city. By the early 1960s, the United States needed a more universal zip code numbering system, so a set of optional ZIP numbers was used throughout the United States on January 1, 1963. A clerk working in the post office, Robert. Robert Moon is considered the founder of ZIP numbering. In 1944, while working as a mail inspector for the Postal Service, he submitted a proposal for ZIP numbers. The Postal Service uses the first three digits of Robert's ZIP code to represent areas within the country. In most cases, the last two digits represent the same meaning as the old postal code. For example: Example B1 John. Smith 3256 Incident Avenue Minneapolis, MN 55416 Example B 200 Second Avenue South #358 St. Petersburg, FL 33701 In 1967, second and third class large mailers were mandated After using this system, it was quickly widely recognized by the public. Initially, the U.S. Postal Service used a cartoon character, Mr. ZIP, to promote ZIP numbers to the public. It is often printed on the edges of stamps or on the cover of booklets together with the words "USE ZIP CODES". However, the only stamp issued by the U.S. Postal Service to promote ZIP numbers did not feature Mr. ZIP. ZIP+4 In 1983, the United States Postal Service began using an improved set of ZIP numbers called "ZIP+4", often referred to as "plus four numbers" or "added numbers". Example C Wikimedia Foundation 200 Second Avenue, South #358 St. Petersburg, FL 33701-4313 In addition, the United States Postal Service offers a service on its website called "Find ZIP Number" that provides a The address format recognized by an optical character recognizer or scanner. ZIP+4 numbers use the original five numbers, plus an additional four numbers, to identify geographic divisions within a five-digit numbered destination, such as a building, a group of apartments, individual bulk recipients, or other areas that could use additional Recognizer is a unit that enhances the efficiency of mail classification and delivery. Usually ZIP+4 numbers are only used for pre-sorting of mail. Emails are generally read by a Multiline Optical Character Reader that can instantly determine a valid ZIP+4 number. When you need to send a parcel to a more precise location, you can affix an eleven-digit Postal Code on the envelope. This technology has greatly improved the speed and accuracy of mail delivery, allowing the cost of mailing services to remain unchanged for ten years. Generally speaking, each outbox has its own ZIP+4 number. The added number is usually the last four digits of the outbox, or, on outboxes with less than four numbers, enough "0"s are added to the ZIP number to make it a four-digit number.

But this is not a uniform rule, so all outboxes have their own ZIP+4 number. Addition number 9998 is often used as the address for letters addressed to the Postmaster General (letters requiring a postmark are usually addressed). The 9999 number is used for ordinary mail or business reply mail whose added number has many digits. A unique ZIP number is typically 0001.

The ZIP number is often translated into a barcode and printed on the envelope to make it easier for machines to sort the mail. Unlike most other barcodes, Postal Network uses long and short barcodes, not the usual thick and thin barcodes. This barcode can be printed on the envelope by any sender (using some word processing software, such as WordPerfect and Microsoft Word), or it can be printed on the envelope by the postal service when processing the mail. The Postal Service usually uses an optical character reader to read barcodes, but will use the naked eye when necessary, because machines sometimes print barcodes on the wrong places on postcards, causing them to be smeared. Mailers who mail large items will receive a discount if they pre-print a barcode on the item. This has higher requirements for email address information; its mailing list must comply with the latest Coding Accuracy Support System (Coding Accuracy Support System

CASS) certification software standards, and must have an effective ZIP+4 number and two additional numbers used to indicate the correct destination (5+4+2, ***11 numbers). In addition, mail must be pre-sorted into a dedicated program and accompanied by a verifiable document. These steps are usually completed by a set of PAVE authentication software that can print barcode addresses. This means that every delivery location within the United States theoretically has its own eleven-digit number. The digits of the delivery location (tens or eleven digits) are calculated based on the first or second number on the address. The U.S. Postal Service has published a set of technical guidelines called CASS to calculate collection points. The last code is a checkpoint calculated from the fifth, ninth or eleventh number. The application only needs to print a number such as /100010001007/ on the twelve o'clock postal network, which is a correct barcode. On barcodes, slashes are translated into start or stop letters (represented by a long bar), and each number is translated into a series of two long bars and three short bars. In business replies, a Facing Identification Mark (FIM) is used to show the location of the mail, because these mails are usually not stamped or printed with fluorescent ink (using postage machines). as the mail is located by the machine). In addition, if the FIM number on the mail is printed with A and C, it means that the mail has a postal network barcode, which allows it to skip the process of being read by the multi-line optical character recognizer and directly use a barcode scanner to read it. Therefore, although polite return and postmarked returns will have a stamp or stamp printed on the postage machine, they will still be printed with a typical FIM A number to indicate that the mail has a postal network barcode. ZIP numbers in various regions of the United States ZIP number distribution map The first digit of the ZIP number indicates which region in the United States (and overseas territories) the number is located in.

This eliminates the need for customers to use other routing indicators, such as the IATA number of the destination airport or train station. ZIP numbers are not only used to track the location of mail, they also provide geographic data for the United States. For example, the U.S. Census Bureau continuously tracks the latitude and longitude of the center point of each ZIP number, and this data is sold by many other companies. This information is often used in direct mail campaigns called "ZIP number marketing." Cashiers in stores sometimes ask for the ZIP number of the customer's address in order to collect information on the customer's shopping patterns. Companies or experts analyze this information to decide where to open new businesses. Finally, ZIP number data is also used to analyze geographical features. Philippines The term "ZIP code" is also used in the Philippines to name its postal code. It is used by the Philippine Postal Corporation. Unlike the ZIP number in the United States, the ZIP number in the Philippines uses four digits. Cities outside Manila use only one number, while Manila uses more than one number. Popular Culture In 1964, Smokey Bear, a bear used by the U.S. Forest Service to promote wildfire prevention, was warmly welcomed by the public. It received many letters from supporters. Therefore it was given its own ZIP number, 20252. In the 1960s, the ZIP number for the location where the main character of the popular TV series Batman lived was 9999979. Although this was obviously not the correct ZIP number, it still brought attention to the ZIP number which was in its infancy at the time. In the film based on the TV series Green Acres, Hooterville's ZIP number is "40516 and a half". The "Public *** Service Notice" under the "*** Consumer Information Center" in the United States is famous for its ZIP number 81009. Newton Falls, Ohio
