ZIP code

ZIP codes are a system of postal codes used by the United States Postal Service (USPS) since 1963. The term ZIP, an acronym for Zone Improvement Plan, was chosen to suggest that the mail travels more efficiently, and therefore more quickly (zipping along), when senders use the code in the postal address. The basic format consists of five decimal numerical digits. An extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP code, a hyphen, and four additional digits that determine a more specific location within a given ZIP code. The USPS provides a free online lookup tool for ZIP codes.

The term ZIP code was originally registered as a servicemark (a type of trademark) by the U.S. Postal Service, but its registration has since expired. USPS style for ZIP is all caps, although style sheets for some publications use sentence case or lowercase.

History

The early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department (USPOD) implemented postal zones for numerous large cities in 1943. For example:

Sunnyside, Queens

Sunnyside is a working and middle class neighborhood in the Western portion of the New York City borough of Queens. It shares borders with Hunters Point and Long Island City to the west, Astoria to the north, Woodside to the east and Maspeth to the south. The neighborhood is part of Queens Community District 2, served by Queens Community Board 2.

The land was originally owned by French settlers in the 1800s. The name "Sunnyside" is derived from Sunnyside Hill Farms, so named by the Bragraws family who owned the land. Sunnyside was a rural hamlet mostly consisting of small farms and marshland. It was incorporated into Long Island City in 1870, and developed into a bedroom community after the Queensboro Bridge was completed in 1909. A large portion of the neighborhood is six-story apartment buildings constructed during the 1920s and '30s.

Sunnyside Gardens subsection

Sunnyside Gardens, listed as a historic district on the National Register of Historic Places, is among the first planned communities in the U.S.

List of ZIP codes in the Philippines

In the Philippines, the Philippine ZIP code is used by the Philippine Postal Corporation (Philpost) to simplify the distribution of mail. While in function it is similar to the ZIP code used in the United States, its form and its usage is quite different. The use of ZIP codes in the Philippines is not mandatory, however it is highly recommended by Philpost that they be used. Also, unlike American ZIP codes, the Philippine code is a four-digit number representing two things: in Metro Manila, a barangay within a city or city district (as in the case for Manila), and outside Metro Manila, a town or city. Usually, more than one code is issued for areas within Metro Manila, and provincial areas are issued one code for every town and city, with some rare exceptions such as Dasmariñas, which has three ZIP codes (4114, 4115, and 4126) and Los Baños, which as two ZIP codes (4030 and 4031 for the University of the Philippines Los Baños).

This article provides a list of Philippine ZIP codes. Cities that have become independent of the province are listed under the province they used to be part of (as is the practice for statistical purposes).

Hamming space

In statistics and coding theory, a Hamming space is usually the set of all binary strings of length N. It is used in the theory of coding signals and transmission.

More generally, a Hamming space can be defined over any alphabet (set) Q as the set of words of a fixed length N with letters from Q. If Q is a finite field, then a Hamming space over Q is an N-dimensional vector space over Q. In the typical, binary case, the field is thus GF(2) (also denoted by Z₂).

In coding theory, if Q has q elements, then any subset C (usually assumed of cardinality at least two) of the N-dimensional Hamming space over Q is called a q-ary code of length N; the elements of C are called codewords. In the case where C is a linear subspace of its Hamming space, it is called a linear code. A typical example of linear code is the Hamming code. Codes defined via a Hamming space necessarily have the same length for every codeword, so they are called block codes when it is necessary to distinguish them from variable-length codes that are defined by unique factorization on a monoid.

Code (album)

Code (stylized as C O D E) is an album by British electronic band Cabaret Voltaire. The track "Don't Argue" was released as a single, as was "Here To Go".

The lyrics (and title) of "Don't Argue" incorporate verbatim a number of sentences from the narration of the 1945 short film Your Job in Germany, directed by Frank Capra. The film was aimed at American soldiers occupying Germany and strongly warned against trusting or fraternizing with German citizens.

Code (law)

A code is a type of legislation that purports to exhaustively cover a complete system of laws or a particular area of law as it existed at the time the code was enacted, by a process of codification. Though the process and motivations for codification are similar in different common law and civil law systems, their usage is different. In a civil law country, a Code typically exhaustively covers the complete system of law, such as civil law or criminal law. By contrast, in a common law country with legislative practices in the English tradition, a Code is a less common form of legislation, which differs from usual legislation that, when enacted, modify the existing common law only to the extent of its express or implicit provision, but otherwise leaves the common law intact. By contrast, a code entirely replaces the common law in a particular area, leaving the common law inoperative unless and until the code is repealed. In a third case of slightly different usage, in the United States and other common law countries that have adopted similar legislative practices, a Code is a standing body of statute law on a particular area, which is added to, subtracted from, or otherwise modified by individual legislative enactments.
