Amazon Standard Identification Number

Last updated

The Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by and its partners for product identification within the Amazon organization. [1]

Alphanumeric is a combination of alphabetic and numeric characters, and is used to describe the collection of Latin letters and Arabic digits or a text constructed from this collection.

With reference to a given set of objects, a unique identifier (UID) is any identifier which is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. There are three main types of unique identifiers, each corresponding to a different generation strategy:

  1. serial numbers, assigned incrementally or sequentially
  2. random numbers, selected from a number space much larger than the maximum number of objects to be identified. Although not really unique, some identifiers of this type may be appropriate for identifying objects in many practical applications and are, with abuse of language, still referred to as "unique"
  3. names or codes allocated by choice which are forced to be unique by keeping a central registry such as the EPC Information Services.

Usage and structure

Although ASINs used to be unique worldwide, global expansion has changed things so that ASINs are only guaranteed unique within a marketplace.[ citation needed ] The same product may be referred to by several ASINs though, and different national sites may use a different ASIN for the same product.[ citation needed ] In general, ASINs are unlikely to be different between the country sites specially if they are for a class of product where the ASIN is based on an externally defined and internationally consistent identifier, such as ISBN for books.[ citation needed ]

Each product sold on is given a unique ASIN. For books with 10-digit International Standard Book Number (ISBN), the ASIN and the ISBN are the same. [2] The Kindle edition of a book will not use its ISBN as the ASIN, although the electronic version of a book may have its own ISBN. In most cases, it is possible to convert an ASIN to obtain a corresponding EAN code, also known as an International Article Number. [3]

International Article Number standard describing a barcode symbology and numbering

The International Article Number is a standard describing a barcode symbology and numbering system used in global trade to identify a specific retail product type, in a specific packaging configuration, from a specific manufacturer. The standard has been subsumed in the Global Trade Item Number standard from the GS1 organization; the same numbers can be referred to as GTINs and can be encoded in other barcode symbologies defined by GS1. EAN barcodes are used worldwide for lookup at retail point of sale, but can also be used as numbers for other purposes such as wholesale ordering or accounting.

ASINs are also used for other items used by (and subsidiaries), such as businesses in the yellow pages (on and OpenSearch feeds.[ citation needed ] subsidiary of based in Palo Alto, California that develops search and advertising technology is a subsidiary of Amazon that develops search engine and search advertising technology.

A serial number is a unique identifier assigned incrementally or sequentially to an item, to uniquely identify it.

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically-stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source and may operate hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC).

The National Drug Code (NDC) is a unique product identifier used in the United States for drugs intended for human use. The Drug Listing Act of 1972 requires registered drug establishments to provide the Food and Drug Administration (FDA) with a current list of all drugs manufactured, prepared, propagated, compounded, or processed by it for commercial distribution. Drug products are identified and reported using the NDC.

An International Standard Serial Number (ISSN) is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is especially helpful in distinguishing between serials with the same title. ISSN are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature.

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 in the sequence input.

Global Trade Item Number (GTIN) is an identifier for trade items, developed by GS1. Such identifiers are used to look up product information in a database which may belong to a retailer, manufacturer, collector, researcher, or other entity.

Accession number (library science) object identifiers used in galleries, libraries, archives, and museums

In libraries, art galleries, museums and archives, an accession number is a unique identifier assigned to, and achieving initial control of, each acquisition. Assignment of accession numbers typically occurs at the point of accessioning or cataloging. The term is something of a misnomer, because the form accession numbers take is often alpha-numeric.

"Bookland" is the informal name for the Unique Country Code (UCC) prefix allocated in the 1980s for European Article Number (EAN) identifiers of published books, regardless of country of origin, so that the EAN namespace can catalogue books by ISBN rather than maintaining a redundant parallel numbering system. In other words, Bookland is a fictitious country that exists solely in EAN for the purposes of non-geographically cataloguing books in the otherwise geographically keyed EAN coding system.

An EAN-8 is an EAN/UPC symbology barcode and is derived from the longer International Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large; for example on cigarettes, pencils, and chewing gum packets. It is encoded identically to the 12 digits of the UPC-A barcode, except that it has 4 digits in each of the left and right halves.

Unique Identification Marking, UID marking, Item Unique Identification or IUID, is a part of the compliance process mandated by the United States Department of Defense. It is a permanent marking method used to give equipment a unique ID. Marking is essential for all equipment with an acquisition cost of over $5,000, equipment which is mission essential, controlled inventory, or serially-controlled. UID-marking is a set of data for assets that is globally unique and unambiguous. The technology used to mark an item is 2D Data Matrix ECC 200 Symbol. UID marking can be used to ensure data integrity and data quality throughout an item's lifecycle; it also supports multi-faceted business applications.
