The Federal Information Processing Standards (FIPS) of the United States are a set of publicly announced standards that the National Institute of Standards and Technology (NIST) has developed for use in computer situs of non-military United States government agencies and contractors. FIPS standards establish requirements for ensuring computer security and interoperability, and are intended for cases in which suitable industry standards do not already exist. AIR FIPS specifications are modified versions of standards the technical communities use, such as the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers (IEEE), and the International Organization for Standardization (ISO).
ISO 4217 is a standard published by the International Organization for Standardization (ISO) that defines alpha codes and numeric codes for the representation of currencies and provides information about the relationships between individual currencies and their minor units. This data is published in three tables:
ISO/IEC 646 is a set of ISO/IEC standards, described as Information technology — ISO 7-bit coded character set for information interchange, and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived.
The North American Numbering Plan is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the telephone country code 1. Some North American countries, most notably Mexico, do not participate with the NANP.
ISO 3166-1 is a standard defining codes for the names of countries, dependent territories, and special areas of geographical interest. It is the first part of the ISO 3166 standard published by the International Organization for Standardization.
ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO, and are used most prominently for the Internet's country code top-level domains. They are also used as country identifiers extending the postal code when appropriate within the international postal system for paper mail, and have replaced the previous one consisting one-letter codes. They were first included as part of the ISO 3166 standard in its first edition in 1974.
UN/LOCODE, the United Nations Code for Trade and Transport Locations, is a geographic coding scheme developed and maintained by United Nations Economic Commission for Europe (UNECE). UN/LOCODE assigns codes to locations used in trade and transport with functions such as seaports, rail and road terminals, airports, Postal Exchange Office and border crossing points. The first issue in 1981 contained codes for 8,000 locations. The version from 2011 contained codes for about 82,000 locations.
ISO 9362 is an international standard for Business Identifier Codes (BIC), a unique identifier for business institutions, approved by the International Organization for Standardization (ISO). BIC is also known as SWIFT-BIC, SWIFT ID, or SWIFT code, after the Society for Worldwide Interbank Financial Telecommunication (SWIFT), which is designated by ISO as the BIC registration authority. BIC was defined originally as Bank Identifier Code and is most often assigned to financial organizations; when it is assigned to non-financial organization, the code may also be known as Business Entity Identifier (BEI). These codes are used when transferring money between banks, particularly for international wire transfers, and also for the exchange of other messages between banks. The codes can sometimes be found on account statements.
A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.
Code page 850 is a code page used under DOS operating systems in Western Europe. Depending on the country setting and system configuration, code page 850 is the primary code page and default OEM code page in many countries, including various English-speaking locales, whilst other English-speaking locales default to the hardware code page 437.
The International Standard Recording Code (ISRC) is an international standard code for uniquely identifying sound recordings and music video recordings. The code was developed by the recording industry in conjunction with the ISO technical committee 46, subcommittee 9, which codified the standard as ISO 3901 in 1986, and updated it in 2001.
Telephone numbers in Russia are administered by Roskomnadzor, and Ministry of Digital Development, Communications and Mass Communications of the Russian Federation. Russia's National Numbering Plan (NNP) is a four-level telephone numbering plan with local, zone, country, and international scopes, implementing a closed numbering plan, in which the number of digits of all national significant numbers (NSN) assigned to subscriber telephones is fixed at ten, with three digits for the area code, and a seven-digit subscriber number which includes a zone code of up to two digits. Internationally, Russia participates in the numbering plans of the International Telecommunication Union (ITU) provided by recommendations E.164 and E.123, using the telephone country code 7.
The National Replacement Character Set (NRCS) was a feature supported by later models of Digital's (DEC) computer terminal systems, starting with the VT200 series in 1983. NRCS allowed individual characters from one character set to be replaced by one from another set, allowing the construction of different character sets on the fly. It was used to customize the character set to different local languages, without having to change the terminal's ROM for different countries, or alternately, include many different sets in a larger ROM. Many 3rd party terminals and terminal emulators supporting VT200 codes also supported NRCS.
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Work on ICD-10 began in 1983, became endorsed by the Forty-third World Health Assembly in 1990, and came into effect in member states on 1 January 1993. It was replaced by ICD-11 on January 1, 2022.
A total of 41 counties, along with the municipality of Bucharest, constitute the official administrative divisions of Romania. They represent the country's NUTS-3 statistical subdivisions within the European Union and each of them serves as the local level of government within its borders. Most counties are named after a major river, while some are named after notable cities within them, such as the county seat.
Code page 921 is a code page used under IBM AIX and DOS to write the Estonian, Latvian, and Lithuanian languages. It is an extension of ISO/IEC 8859-13. The original code page matched ISO/IEC 8859-13 directly.
