GS1 Canada vs GS1 US — Which Should You Register With?
If you are a Canadian business getting ready to put barcodes on your products, you will quickly encounter a question that trips up almost every first-time seller: do you register with GS1 Canada or GS1 US? The concern is understandable. Many of the largest sales channels — Amazon, Walmart, Google Shopping — are US-headquartered, and a lot of barcode advice on the internet is written for US sellers. It is easy to assume that selling in the US requires a US-issued barcode.
The straightforward answer is: if your business is based in Canada, register with GS1 Canada. Your Canadian GTINs will work everywhere US GTINs work, without any additional registration or conversion. Here is why, and how.
How GS1 Works — The Global Number Space
GS1 is an international standards organisation with member organisations in over 115 countries. Each member organisation — GS1 Canada, GS1 US, GS1 UK, GS1 Australia, and so on — issues Company Prefixes to businesses in their country. All of these prefixes exist in a single global numbering space. The GS1 GEPIR database (the Global Electronic Party Information Registry) is a worldwide lookup system that maps every Company Prefix to its registered company, regardless of which national GS1 member issued it.
When Amazon validates a GTIN for a new product listing, it queries GEPIR. When Walmart validates a GTIN during item setup, it queries GEPIR. The query result is the same whether the prefix was issued by GS1 Canada in Ottawa or GS1 US in New Jersey. There is no separate US or Canadian section of the registry — it is one global database.
The Technical Equivalence
GS1 Canada issues Company Prefixes in the same 0-prefix range as GS1 US. This means every GTIN issued by GS1 Canada is a standard GTIN-12 number that encodes as a UPC-A barcode — the standard barcode format used at North American retail checkout. A UPC-A barcode on a Canadian product is physically identical to a UPC-A barcode on a US product. The retail scanner at a Walmart US store cannot tell the difference between a GS1 Canada prefix and a GS1 US prefix, and neither can Amazon's systems.

| Sell to Target, Home Depot, Costco US | Yes |
| Sell internationally (EU, UK, Australia) | Yes — convert to EAN-13 by prepending a zero |
The Only Real Difference: Who You Pay
The functional difference between GS1 Canada and GS1 US registration is purely administrative. The annual membership fee for GS1 Canada is billed in Canadian dollars to a Canadian organisation. The annual membership fee for GS1 US is billed in US dollars to a US organisation. The prefix you receive, the GTINs you generate from it, and the barcodes you print from those GTINs are technically equivalent regardless of which you choose.
For Canadian businesses, registering with GS1 Canada has practical advantages: the membership agreement is governed by Canadian law, customer support is available in English and French during Canadian business hours, and the GS1 Canada product registry integrates with Canadian retail sourcing systems used by major domestic buyers.
Do You Need to Register with Both?
No. This is a common misconception. You register once, with one GS1 member organisation, and you use those GTINs everywhere. There is no requirement, advantage, or reason to have both a GS1 Canada prefix and a GS1 US prefix unless you are operating two legally separate businesses — one in each country — and need distinct brand identities registered to each entity.
Some sellers register with GS1 US despite being based in Canada because they encounter US-focused advice online, or because they initially plan to sell primarily in the US and assume that requires a US registration. This is unnecessary. The functional result is identical either way.
What About International Selling?
Your GS1 Canada GTIN-12 numbers encode as UPC-A barcodes. For selling in Europe, Australia, Japan, or other international markets — including Amazon's international marketplaces — you will typically need EAN-13 format. This does not require a new registration. Any GTIN-12 from a 0-prefix can be expressed as a GTIN-13 (EAN-13) by prepending a single zero. The number remains the same product identity; the barcode format changes from 12-digit UPC-A to 13-digit EAN-13. BatchPrintGTIN generates both formats from the same number.
The Bottom Line
Register with GS1 Canada if you are a Canadian business. Your GTINs work at every US and international retailer and marketplace exactly as GS1 US GTINs do. You will save on currency exchange, have a simpler administrative relationship with a Canadian organisation, and achieve identical barcode functionality for all your sales channels. Once registered, use BatchPrintGTIN's GTIN Builder to generate your full product barcode set, and the PDF Page Designer to format your labels for printing.
