EANEuropean Article Number

An EAN (originally European Article Number, now formally International Article Number) is a 13-digit barcode standard used for product identification across Europe and most of the world outside North America.

In the GS1 standards system, an EAN is a specific format of GTIN — specifically GTIN-13. It's not a separate identifier; it's the 13-digit version of the same global standard. The European version of what Americans call a UPC.

For UK brands, EAN is the default identifier — printed on packaging, used by every UK retailer's POS system, recognised across the EU and globally.

How an EAN is structured

A standard EAN-13 breaks into four parts:

Country/GS1 Prefix | Manufacturer | Item Number | Check Digit
      3 digits     |   ~6 digits  |   ~3 digits |   1 digit

• Country/GS1 prefix. Identifies which national GS1 office issued the company prefix. UK brands typically use 500–509 (allocated to GS1 UK). 400–440 are German, 540–549 are Belgian, etc.
• Manufacturer prefix. Issued by your local GS1 within their country's range. Identifies the brand.
• Item number. Allocated by the brand within its prefix. Identifies the variant.
• Check digit. Calculated mathematically from the previous 12 digits.

The country prefix is where the GTIN was issued, not where the product is made or sold. A UK brand applying through GS1 UK gets a 5xx prefix even if their products are manufactured in China and sold worldwide.

EAN vs UPC vs GTIN

The three identifiers most often confused at retail:

• GTIN — umbrella term for global product identifiers issued through GS1.
• UPC — 12-digit GTIN, primary North American format.
• EAN — 13-digit GTIN, primary European and international format.

The difference between UPC and EAN is one leading digit. Convert between them by adding or removing a leading 0 (in most cases). Modern POS scanners read both formats automatically. The standards converged years ago — EAN-13 is now the global default; UPC-A persists in US-only contexts.

If you're trying to decide which to use, the rule of thumb: print EAN-13 on your packaging. It's accepted everywhere, including the US (where scanners read it as a UPC with an implied leading 0).

When UK brands need EANs

Almost always. Triggers:

1. Any UK retail. Tesco, Sainsbury's, Boots, Argos, John Lewis — all use EAN at POS.
2. EU marketplace selling. Amazon EU, Cdiscount, Bol.com, Allegro — all require valid EANs.
3. Cross-border logistics. Customs and freight systems use EAN for product identification on shipping documents.
4. Online retail in most non-US markets. Australia, NZ, Asia-Pacific generally use EAN.

If you're a UK or EU brand, allocate EANs from day one. Adding them later is harder than starting with them.

Country prefixes (the misconception)

A common misconception: a 5xx EAN means the product was made in the UK. Not true.

The country prefix indicates where the GTIN was registered, not where the product is manufactured. A UK brand can register all its GTINs through GS1 UK (5xx prefix) regardless of where products are produced. A French brand using GS1 France gets a 3xx prefix even if it manufactures in the UK.

The number is purely an administrative identifier of the issuing GS1 office. It's not a country-of-origin signal — that's separate (and usually printed elsewhere on the packaging).

How UK brands get EANs

Apply through GS1 UK. You'll receive a company prefix and the right to allocate item numbers within it. The annual fee scales by company size and the number of GTINs you'll need.

Cheap third-party EAN resellers exist — they bought GS1 prefixes in bulk and resell individual numbers. Most major retailers and Amazon EU now reject these. The annual GS1 UK fee is small relative to the cost of having a major retail launch blocked.

Common EAN mistakes

• Treating the country prefix as country-of-origin. It indicates the issuing GS1 office, not where the product is made.
• Buying cheap third-party EANs. Major retailers and marketplaces increasingly reject these. Use legitimately registered GS1 EANs.
• Reusing an EAN across product variants. Each sellable variant needs its own.
• Forgetting to assign EANs to bundles. A gift set is a separate sellable unit and needs its own EAN, distinct from the EANs of the components.
• Not maintaining the EAN-to-SKU mapping. Two systems both holding identifiers, neither agreeing — classic source of stock and listing errors.
