EAN (European Article Number): what it is, how it works and what it does
EAN (European Article Number) is a 13-digit numeric identification standard assigned to products for registration and tracking in supply chains and points of sale. Available evidence shows codes with the 840 prefix in Spanish e-commerce listings.
EAN (European Article Number) is a standard for numeric product identification used to assign a unique code to commercial items. Its primary purpose is to enable unambiguous identification of a product in distribution, inventory, and retail contexts.
Observable structure
The EAN codes documented in the available evidence are 13-digit numeric sequences. For example, the values 0840353960640, 0840353950092, and 0840353950030 share the prefix 840, indicating they belong to products registered under the same geographic or manufacturer prefix.
Operating principles
- Uniqueness: each code identifies a specific product; the three distinct codes in the evidence correspond to three different articles.
- Common prefix: the match in the leading digits (
08403539) suggests the products originate from the same manufacturer or registration group. - Fixed numeric format: the constant 13-character length facilitates optical scanner reading and database indexing.
Applications
The presence of EAN codes in e-commerce listings (such as www.amazon.es) confirms their use in:
- Product identification in sales listings.
- Search and cataloguing on e-commerce platforms.
- Inventory registration and supply-chain traceability.
Scope and limitations
The available evidence is limited to three codes observed on a single e-commerce domain. No information is available on the full internal structure of the code (check digit, GS1 prefix, manufacturer prefix) or on its adoption in other markets or formats (EAN-8, EAN-13, GTIN-14).
Interpretation in a product
When a code labelled EAN is found on a product listing, it is interpreted as the standard numeric identifier of the article. The presence of a common prefix across several codes allows one to infer they belong to the same manufacturer or product line. The code does not describe product characteristics; it solely identifies the item uniquely within the registration system.
The three documented codes (0840353960640,0840353950092,0840353950030) share the prefix08403539, grouping them under the same registration origin.
