How Do I Register a Barcode?

  • UPC and EAN barcodes are GS1-compliant identifiers that do not store product data; retailers enter your product information manually.
  • There is no global barcode database; each retailer maintains its own private POS system.
  • Barcode registration means assigning your GTINs internally and providing product details to every store or platform where you sell.
  • Submitting your data to each sales channel ensures your GTIN-12 or GTIN-13 is recognized when scanned.

This question often comes in the form of:

  • “How do I get my info to appear when the barcode is scanned?”
  • “Why doesn’t my product show up on Google when I search the barcode?”

Let’s start by clearing up two major misconceptions.

What is the myth that barcodes contain product data?

Myth #1: “The bars in a UPC or EAN code contain my product data like the name and price.”
❌ False. UPCs and EANs are simple numbers. They do not store product details. Just like a phone number, the barcode is only an identifier that points to information stored elsewhere.

Why do people think there is a global barcode database?

Myth #2: “Barcodes and their product data get uploaded to a global database that all stores access.”
❌ False. There is no universal or global barcode database. Every retailer uses its own private POS system. When a product displays a name or price during checkout, it is because the retailer manually entered that data into their internal system.

So, how do you actually register a barcode?

Step 1: Assign your barcodes internally

Match each barcode number to a specific product in your own system. This is your responsibility. Use a spreadsheet or inventory software and keep backups to avoid data loss.

Step 2: Provide your product info to each store

When selling through a retailer or distributor, you must submit your product information — including the matching UPC or EAN — so it can be added to their POS system. This is how your barcode becomes recognized when scanned.

Step 3: Repeat for each new sales channel

Every new store, marketplace, distributor, or website requires the same process. No retailer shares a universal product database. Each system must manually receive your GS1-compliant product data.

Can my barcode be publicly searchable?

BarCodesTalk hosts the largest public database of owned barcodes, available here: https://www.barcodestalk.com/gepir. If you purchased your barcode(s) from us, your listing is automatically created and updated so others can verify GTIN ownership.

Why do retailers individually require my product data?

Every store, website, and POS system functions as a private internal database. To get your product listed, you must contact the retailer and follow their onboarding steps. Each has its own process for uploading and managing data tied to your UPC or EAN.
