How to Get a GS1 Barcode (Step-by-Step Guide for Brands & Founders)

If you're here, you're probably preparing to sell into retail, Amazon, or wholesale distribution.

That means you need real, legitimate barcodes — not random numbers from a reseller.

This guide walks you through exactly how to get a GS1 barcode properly, explains company prefixes vs single GTINs, outlines costs (UK, US, EU examples), and shows you the beginner mistakes that can quietly damage your brand later.

This is written for serious founders.

What Is GS1? (And Why It Matters Globally)

GS1 is a global non-profit organisation that creates and manages the international standards behind retail barcodes.

They operate in over 100 countries through local offices (e.g., GS1 UK, GS1 US, GS1 Germany, GS1 France, GS1 Australia).

When you buy a barcode from GS1, you are:

Registering your company in the global GS1 database
Receiving legitimate GTINs (Global Trade Item Numbers)
Enabling retailers to verify your brand as the barcode owner

Retailers, Amazon, distributors and marketplaces check the GS1 database. If your brand name doesn't match the barcode registration, you can be blocked.

If you want long-term retail credibility, GS1 is the standard.

Step-by-Step: How to Get a GS1 Barcode

Step 1: Register With Your Local GS1 Office

Go to the official GS1 organisation in your country. You can find your local office in the GS1 global member directory.

Major markets (direct links):

GS1 UK — United Kingdom
GS1 US — United States
GS1 Ireland — Ireland
GS1 Germany — Germany
GS1 France — France
GS1 Australia — Australia
GS1 Canada — Canada
GS1 New Zealand — New Zealand
GS1 Netherlands — Netherlands
GS1 Italy — Italy
GS1 Spain — Spain

Legal company name
Registered address
VAT / tax ID (in many countries)
Contact details

Important: Register in the country where your business is legally established.

Step 2: Choose Between a Company Prefix or Single GTIN

This is where founders often get confused.

Option A: Single GTIN

You buy one barcode number for one product.

Best for:

Testing a single SKU
Very small brands
Early validation stage

Limitations:

Each new product requires buying another single GTIN
Less scalable
No structured numbering control

Option B: Company Prefix (Recommended for Brands)

You buy a GS1 Company Prefix, which allows you to generate multiple GTINs yourself.

Example:

You receive a prefix like 1234567
You create unique numbers for each SKU using that prefix

Best for:

Brands with multiple SKUs
Anyone planning growth
Retail or wholesale businesses

If you're building a serious brand, the company prefix is usually the smarter long-term decision.

If you're unsure which barcode format you actually need (EAN-13, UPC-A, ITF-14, etc.), read:

Those guides clarify format vs number structure — two different things beginners often mix up.

What Does a GS1 Barcode Cost?

Costs vary slightly by country, but the structure is similar worldwide.

UK (GS1 UK)

Initial joining fee
Annual renewal fee
Cost increases based on number of GTINs

Example (approximate): Small starter licence (up to 10 GTINs): a few hundred pounds per year

See GS1 UK pricing for current rates.

US (GS1 US)

One-time fee for single GTIN
Company prefix fee depends on capacity (10, 100, 1,000+ GTINs)
Annual renewal required for prefixes

See GS1 US membership for details.

EU Countries (Germany, France, Ireland, etc.)

Similar structure:

Membership fee
Annual renewal
Prefix cost based on scale

See your local GS1 office via the member directory.

Important: GS1 barcodes are not a one-time "lifetime purchase" when you buy a prefix. There is usually an annual licence fee.

If someone offers "lifetime barcodes" cheaply, they are almost certainly a reseller.

Why You Should NOT Buy Barcodes From Resellers

This is where many new sellers go wrong.

Resellers buy old company prefixes and sell individual barcode numbers cheaply.

Problems:

The barcode is not registered to your company
Retailers can see the mismatch
Amazon can reject listings for invalid GTINs
Large retailers can refuse onboarding
You lose long-term credibility

In serious retail environments, barcode ownership is verified.

You might "get away with it" early on. But if you're building a brand that plans to sell into chains, wholesale, or internationally, this shortcut can cost you far more later.

Buy directly from GS1. Every time.

Common Beginner Mistakes

1. Confusing Barcode Format With GTIN Structure

EAN-13, UPC-A, ITF-14 — these are formats.

GTIN-12, GTIN-13, GTIN-14 — these are number structures.

Different concepts. Many founders mix them up.

2. Buying Only One GTIN When Planning 10 SKUs

Short-term thinking leads to higher long-term cost.

If you plan to expand, consider a prefix early.

3. Not Planning Variants Properly

Each variation usually needs its own GTIN:

Size
Colour
Edition
Pack size

A red notebook and a blue notebook? Two GTINs.

4. Not Understanding Carton Codes

Retailers often require outer carton barcodes (e.g., ITF-14 or GS1-128).

Your product GTIN is not enough. See Carton Barcodes: ITF-14 vs GS1-128.

5. Using Free Online Barcode Generators Without Owning a GTIN

A barcode image generator is fine.

But the number inside it must be legitimate.

The barcode graphic is just a visual representation of your GTIN.

Quick Summary: The Correct Way

Register with your local GS1 office
Decide between single GTIN or company prefix
Pay official GS1 fees
Allocate GTINs correctly per SKU
Generate barcode graphics using your real numbers

Do it properly once and you never worry about it again.

FAQ: Getting a GS1 Barcode

Do I legally have to use GS1?

Technically no — but practically yes if you want to sell into retail, Amazon, or major marketplaces.

Retailers expect GS1-registered GTINs.

Can I use a UK GS1 barcode to sell in the US?

Yes.

GS1 standards are global. A GTIN issued by GS1 UK is valid worldwide.

What is the difference between GTIN-12, GTIN-13 and GTIN-14?

They are different lengths of Global Trade Item Numbers used in different contexts.

For a full breakdown, see: GTINs Explained

Is a UPC the same as a GS1 barcode?

UPC is a barcode format commonly used in North America.

The number inside the UPC is still a GTIN issued by GS1.

What happens if I stop paying GS1 annual fees?

Your company prefix can become inactive, which may create issues with verification and retail relationships.

If you're building a long-term brand, treat GS1 membership as infrastructure — not an optional expense.

Final Advice for Founders

If you're serious about wholesale, Amazon, or retail distribution, treat barcodes like legal structure or accounting.

Not glamorous. Not optional. Foundational.

Make the right decision once — and scale cleanly.
