In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications.
A postal code is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail.
A ZIP Code is a system of postal codes used by the United States Postal Service (USPS). The term ZIP was chosen to suggest that the mail travels more efficiently and quickly when senders use the code in the postal address.
Postal codes used in the United Kingdom, British Overseas Territories and Crown dependencies 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 several addresses or a single major delivery point.
Code 39 is a variable length, discrete barcode symbology defined in ISO/IEC 16388:2007.
A Postal Index Number refers to a six-digit code in the Indian postal code system used by India Post. On 15 August 2022, the PIN system celebrated its 50th anniversary.
POSTNET is a barcode symbology used by the United States Postal Service to assist in directing mail. The ZIP Code or ZIP+4 code is encoded in half- and full-height bars. Most often, the delivery point is added, usually being the last two digits of the address or PO box number.
PDF417 is a stacked linear barcode format used in a variety of applications such as transport, identification cards, and inventory management. "PDF" stands for Portable Data File. The "417" signifies that each pattern in the code consists of 4 bars and spaces in a pattern that is 17 units (modules) long. The PDF417 symbology was invented by Dr. Ynjiun P. Wang at Symbol Technologies in 1991. It is defined in ISO 15438.
Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1. It generally results in more compact barcodes compared to other methods like Code 39, especially when the texts contain mostly digits. Code 128 was developed by the Computer Identics Corporation in 1981.
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.
Inter-range instrumentation group timecodes, commonly known as IRIG timecode, are standard formats for transferring timing information. Atomic frequency standards and GPS receivers designed for precision timing are often equipped with an IRIG output. The standards were created by the Tele Communications Working Group of the U.S. military's Inter-Range Instrumentation Group (IRIG), the standards body of the Range Commanders Council. Work on these standards started in October 1956, and the original standards were accepted in 1960.
PostBar, also known as CPC 4-State, is the black-ink barcode system used by Canada Post in its automated mail sorting and delivery operations. It is similar to other 4 State barcode systems used by Australia Post and the United Kingdom's Royal Mail, but uses an obscured structure and encoding system unique to Canada Post. This particular bar code system is used on "flats" and parcels.
Ukraine uses five-digit numeric postal codes that are written immediately to the right of the city or settlement name.
A Peruvian postal code is a five-digit string that comprises part of a postal address in Peru. Prior to 2011, only the major cities of Lima and Callao used postal codes. However, in February 2011 a nationwide system was implemented which employs a five-digit numeric format. Similar to the postal codes of Mexico, Brazil, Australia, the United States, and elsewhere, postal codes in Peru are strictly numerical, using only numbers.
The Intelligent Mail Barcode (IMb) is a 65-bar barcode for use on mail in the United States. The term "Intelligent Mail" refers to services offered by the United States Postal Service for domestic mail delivery. The IM barcode is intended to provide greater information and functionality than its predecessors POSTNET and PLANET. An Intelligent Mail barcode has also been referred to as a One Code Solution and a 4-State Customer Barcode, abbreviated 4CB, 4-CB or USPS4CB. The complete specification can be found in USPS Document USPS-B-3200. It effectively incorporates the routing ZIP Code and tracking information included in previously used postal barcode standards.
Colombia is a unitary republic conformed by thirty-two departments and a Capital District. Each department has a Governor (gobernador) and a Department Assembly, elected by popular vote for a four-year period. The governor cannot be re-elected consecutively.
In computing, decimal32 is a decimal floating-point computer numbering format that occupies 4 bytes (32 bits) in computer memory. It is intended for applications where it is necessary to emulate decimal rounding exactly, such as financial and tax computations. Like the binary16 format, it is intended for memory saving storage.
In computing, decimal64 is a decimal floating-point computer numbering format that occupies 8 bytes in computer memory. It is intended for applications where it is necessary to emulate decimal rounding exactly, such as financial and tax computations.
Germany introduced postal codes on 25 July 1941, in the form of a two-digit system that was applied initially for the parcel service and later for all mail deliveries. This system was replaced in 1962 in West Germany by a four-digit system; three years later East Germany followed with its own four-digit system. Whereas the Federal Republic introduced a system with space left for the East German postal system after a possible reunification, such as by omitting all codes starting with '1' and '9', the German Democratic Republic had a system that used all codes starting from '1' to '9' just for East Germany.
BCD, also called alphanumeric BCD, alphameric BCD, BCD Interchange Code, or BCDIC, is a family of representations of numerals, uppercase Latin letters, and some special and control characters as six-bit character codes.
