ISO 7064 defines algorithms for calculating check digit characters.
It is referred to by other ISO standards:
and by other systems:
A check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data. It consists of one or more digits computed by an algorithm from the other digits (or letters) in the sequence input.
With a check digit, one can detect simple errors in the input of a series of characters (usually digits) such as a single mistyped digit or some permutations of two successive digits.EIDR
EIDR, or the Entertainment Identifier Registry, is a global unique identifier system for a broad array of audio visual objects, including motion pictures, television, and radio programs. The identification system resolves an identifier to a metadata record that is associated with top-level titles, edits, DVDs, encodings, clips, and mash-ups. EIDR also provides identifiers for Video Service providers, such as broadcast and cable networks.
As of February, 2018, EIDR contains over 1.8 million records, including 298K movies, and 794K episodes of over 25K TV series.
EIDR is an implementation of a Digital Object Identifier (DOI).Global Release Identifier
The Global Release Identifier (GRid) is a system to identify releases of digital sound recordings (and other digital data) for electronic distribution. It is designed to be integrated with identification systems deployed by key stakeholders from across the music industry.
(GRid should not be confused with the Global Repertoire Database (GRD), a system to track ownership and control of musical works, which was planned from 2008-2014 but ultimately failed.)International Bank Account Number
The International Bank Account Number (IBAN) is an internationally agreed system of identifying bank accounts across national borders to facilitate the communication and processing of cross border transactions with a reduced risk of transcription errors. It was originally adopted by the European Committee for Banking Standards (ECBS), and later as an international standard under ISO 13616:1997. The current standard is ISO 13616:2007, which indicates SWIFT as the formal registrar. Initially developed to facilitate payments within the European Union, it has been implemented by most European countries and numerous countries in the other parts of the world, mainly in the Middle East and in the Caribbean. As of February 2016, 69 countries were using the IBAN numbering system.The IBAN consists of up to 34 alphanumeric characters comprising: a country code; two check digits; and a number that includes the domestic bank account number, branch identifier, and potential routing information. The check digits enable a check of the bank account number to confirm its integrity before submitting a transaction.International Standard Text Code
The International Standard Text Code (ISTC) is a unique identifier for text-based works. The ISO standard was developed by TC 46/SC 9 and published in March 2009 as ISO 21047:2009. The authority responsible for implementing the standard is The International ISTC Agency.Personal identification number (Croatia)
The Personal identification number (Croatian: Osobni identifikacijski broj or OIB) is a permanent national identification number of every Croatian citizen and legal persons domiciled in the Republic of Croatia. OIB is determined and assigned by the Tax Administration (Porezna uprava) of the Croatian Ministry of Finance. Personal identification number gradually replaced the Unique Master Citizen Number (JMBG), which had been set up and used in former Yugoslavia.Resident Identity Card
The Chinese identity card (Chinese: 居民身份证; pinyin: Jūmín Shēnfènzhèng) is an official identity document for personal identification in the People's Republic of China. According to the second chapter, tenth clause of the Resident Identity Card Law, residents are required to apply for resident identity cards from the local Public Security Bureau, sub-bureaus or local executive police stations.VAT identification number
A value added tax identification number or VAT identification number (VATIN) is an identifier used in many countries, including the countries of the European Union, for value added tax purposes.
In the EU, a VAT identification number can be verified online at the EU's official VIES website. It confirms that the number is currently allocated and can provide the name or other identifying details of the entity to whom the identifier has been allocated. However, many national governments will not give out VAT identification numbers due to data protection laws.
The full identifier starts with an ISO 3166-1 alpha-2 (2 letters) country code (except for Greece, which uses the ISO 639-1 language code EL for the Greek language, instead of its ISO 3166-1 alpha-2 country code GR) and then has between 2 and 13 characters. The identifiers are composed of numeric digits in most countries, but in some countries they may contain letters.
Foreign companies that trade with non-enterprises in the EU may have a VATIN starting with "EU" instead of a country code, e.g. Godaddy USA EU826010755 and Amazon USA AWS EU826009064.
