EAN-8

Type1D LinearUniversal

Overview

EAN-8 is the 8-digit linear barcode of the EAN/UPC symbology family. It encodes a GTIN-8 (Global Trade Item Number) — seven data digits plus one mod-10 check digit — and is the short-form sibling of ean-13. EAN-8 was introduced for use on small packages where a full-size EAN-13 would not fit, such as cigarettes, pencils, and chewing-gum packets.

EAN-8 is standardised as ISO/IEC 15420 (jointly with ean-13, upc-a and upc-e) and governed by GS1. Because the supply of 8-digit numbers is far smaller than the 13-digit space, GS1 member organisations issue GTIN-8s sparingly, typically only when a company can demonstrate that a standard ean-13 cannot physically fit on the product.

History

EAN-8 was derived from the longer ean-13 system created by the European Article Numbering association in the late 1970s. It was added to provide a compact symbol for items too small to carry a 13-digit code, mirroring the role that the zero-suppressed upc-e plays in the North American upc-a world. The numbering organisation, originally EAN International, merged with the Uniform Code Council and became GS1 in 2005.

Technical specification

Digits: 8 (7 data + 1 check digit).
Structure: a 2-3 digit GS1 prefix (numbering authority), an item reference, and the check digit. Unlike ean-13 there is no separate manufacturer/product split — the short number is allocated directly by the GS1 member organisation.
Encoding: each digit uses 7 modules (2 bars + 2 spaces). The four left-hand digits use odd-parity L-codes and the four right-hand digits use the R-codes. Unlike ean-13, EAN-8 does not use even-parity left-hand (G) patterns, so there is no hidden digit encoded by parity — all eight digits are explicit.
Guard bars: start (101), centre (01010), and end (101) guard patterns. The full symbol is 67 modules wide: 3 + (4 × 7) + 5 + (4 × 7) + 3.
Check digit: mod-10 — weight the first seven digits by 3 and 1 starting from the left (3,1,3,1,3,1,3), sum, and choose the digit that brings the total to the next multiple of 10. The weighting starts with 3 because EAN-8 has an odd number of data digits before the check digit.
Internal/in-store range: GTIN-8 values in the 00000000-00009999 range are reserved for internal use such as in-store numbering and are not globally unique.

Use cases

Small retail packaging — the primary use; products too small for an ean-13, such as cigarettes, pens, confectionery, and cosmetics samples.
Point of sale — read by the same retail scanners as ean-13 and upc-a, since all are EAN/UPC family symbologies.
GTIN carrier — the GTIN-8 functions as a normal trade item identifier and can be referenced by higher-level GS1 logistics standards such as gs1-128.

Implementations

EAN-8 is supported by essentially every barcode scanner, POS system, and barcode-generation library in existence, alongside ean-13 and upc-a. It is a default symbology in open-source decoders such as ZXing and ZBar and is produced by all major label printers.

Comparison

Standard	Digits	Region	Notes
EAN-8	8	Global	Short form for small packs
ean-13	13	Global	Full-size global retail code
upc-a	12	US/Canada	EAN-13 with leading zero
upc-e	8 (6 shown)	US/Canada	Zero-suppressed UPC-A
gs1-databar	varies	Global	Carries GTIN + attributes in less space

EAN-8 is the global short-form symbol; the North American equivalent for small packages is the zero-suppressed upc-e. Both exist to fit a GTIN onto items too small for ean-13 or upc-a. For richer data (batch, expiry, weight) GS1 systems move to gs1-128 or gs1-databar.

Fun facts

Unlike its sibling ean-13, EAN-8 encodes every one of its digits explicitly — there is no clever parity trick hiding an extra digit, because the symbol is short enough not to need one.
GTIN-8 numbers are treated as a scarce resource: GS1 will generally only issue one if you can prove a normal ean-13 will not fit on the product.

Status

EAN-8 is active and remains the standard compact retail barcode worldwide. GS1's "Sunrise 2027" initiative encourages retailers to also accept 2D codes (gs1-databar, gs1-qr-code) at POS, but EAN-8 is expected to remain in use for small packaging for the foreseeable future.

Deployments

EAN-8 is deployed at retail point of sale worldwide on small consumer packages that cannot accommodate a full ean-13. It is read by the same scanner installed base as the rest of the EAN/UPC family and serves as a GTIN-8 carrier for trade items throughout GS1 systems.
