EAN-13 vs UPC: Which Barcode Should You Use? (Complete Guide

If you're working with barcodes, you've probably asked:

👉 Should I use EAN-13 or UPC?
👉 Are they the same?
👉 Which one does Amazon require?

Let’s break it down in the simplest way possible.


What is EAN-13?

EAN-13 (European Article Number) is a 13-digit barcode used internationally.

It’s the most common barcode format worldwide and is widely accepted in retail systems.

Example:

1234567890123


What is UPC?

UPC (Universal Product Code) is a 12-digit barcode mainly used in the United States and Canada.

Example:

123456789012


Key Differences Between EAN-13 and UPC

Feature| EAN-13| UPC
Digits| 13| 12
Usage| Global| US & Canada
Format| International standard| Regional standard
Amazon Compatibility| Yes| Yes


Can You Convert UPC to EAN-13?

Yes.

EAN-13 is basically a UPC with a leading zero.

So:

UPC: 123456789012
EAN-13: 0123456789012

This is why many systems treat them as compatible.


Which Barcode Should You Use?

Use EAN-13 if:

  • You sell internationally
  • You want global compatibility

Use UPC if:

  • You sell mainly in the US/Canada
  • Your supplier already provides UPC

What About Amazon FBA?

Amazon accepts both.

However:

👉 Many sellers end up using FNSKU instead of UPC/EAN

Because:

  • It uniquely identifies your product
  • Prevents listing conflicts

Common Mistakes to Avoid

❌ Using the wrong barcode format
❌ Generating low-quality images
❌ Printing incorrect sizes

These mistakes can cause serious issues in logistics and scanning.
