Technical Details

EAN Technical Details

EAN-13 Format

The standard EAN is 13 digits:

  • Digits 1-3: Country/region code (e.g., 400-440 = Germany)
  • Digits 4-12: Product identifier
  • Digit 13: Check digit

EAN-8 Format

Shortened 8-digit version for small packages. RocketSource supports both EAN-8 and EAN-13.

Relationship to GTIN

EAN-13 is also known as GTIN-13 (Global Trade Item Number). Amazon uses GTIN as the umbrella term: GTIN-12 = UPC, GTIN-13 = EAN, GTIN-14 = Case/carton codes.

FAQs

Frequently Asked Questions

Q: How many EANs can I convert at once?

A: Up to 50,000 per week with a free account. Our paid plans offer higher limits for high-volume sellers.

Q: Do EANs work on Amazon US?

A: Yes. Amazon's catalog links EANs to ASINs across all marketplaces. A product's EAN will match its US listing if one exists.

Q: What if my EAN starts with 0?

A: An EAN starting with 0 is effectively a UPC with a leading zero. RocketSource handles this automatically—you don't need to strip the zero.

Q: Can I mix EANs and UPCs in one upload?

A: Yes. Our system auto-detects the identifier type and processes accordingly.

Q: What's the match rate for EANs?

A: Similar to UPCs—typically 90%+ for products actively sold on Amazon. International or region-specific products may have lower match rates on Amazon US.

Q: Do you support EAN-8?

A: Yes. EAN-8 (8-digit codes for small packages) are supported alongside EAN-13.
