What Code Do I Need for My Product? (Customer Decision Guide)
Choosing the right barcode format depends on where your product is sold, the packaging substrate, and scanner infrastructure:
Should I use UPC-A or Code 128 for my Shopify store?
If you are selling products in external retail marketplaces (like Amazon or Google Shopping), use official GS1 UPC-A barcodes. If you only sell on your own Shopify store and physical boutique, Code 128 using your internal SKUs is fast and free.
How do I add barcodes to my Shopify products?
In your Shopify Admin, navigate to Products > Select Product > Inventory section, and paste the barcode number into the 'Barcode (ISBN, UPC, GTIN, etc.)' field.
Shopify POS & Google Shopping Barcode Policy
- Shopify and Shopify POS are registered trademarks of Shopify Inc. UniversalCodeMaker is an independent software tool not endorsed by Shopify.
- Google Shopping and marketplace integrations require authentic GS1 GTINs. Do not enter fabricated UPC numbers into Shopify if syncing with Google Merchant Center.
- Ensure thermal labels use high-density thermal paper to prevent barcode fading under retail store lighting.
Frequently Asked Questions
Does Shopify require official GS1 UPC or EAN barcodes for products?
It depends on where you sell. If you only sell on your online store or in-person using Shopify POS, you do not need official GS1 barcodes—you can use free Code 128 barcodes based on your own internal variant SKUs. However, if you sync products to sales channels like Google Shopping, Amazon, Walmart, or Meta commerce, those external marketplaces mandate authentic GS1 UPC-A or EAN-13 barcodes registered under your brand prefix.
Where do I enter barcode numbers into the Shopify Admin dashboard?
In Shopify Admin, navigate to Products and select an item. For single-variant products, scroll to the Inventory section and enter the number in the "Barcode (ISBN, UPC, GTIN, etc.)" field. For products with multiple options (sizes/colors), scroll to the Variants table, click Edit on each variant row, and enter the unique barcode in that variant's inventory settings.
How can I print barcode price tags for my Shopify catalog without paying monthly app fees?
Third-party Shopify app store barcode tools frequently charge $10 to $30 per month. UniversalCodeMaker allows you to export your product catalog from Shopify Admin (Products > Export > All products as CSV), copy the SKU or barcode column into our Bulk Barcode Generator, and instantly download print-ready Avery 5160 PDF sheets or thermal roll graphics—completely free with zero subscriptions.
What label sizes work best with desktop thermal printers for Shopify retail?
The retail standard for clothing, gifts, and shelf tags is 2.25" × 1.25" (57 mm × 32 mm) or 2" × 1" direct thermal rolls. This size provides ample area for the product title, variant attribute (e.g., "Size: M / Black"), price, and a scannable 1D barcode with 10X quiet zones. For standard office laser/inkjet printers, 30-up Avery 5160 label sheets (1" × 2-5/8") are widely used.
Which barcode scanners are compatible with Shopify POS on iPad and iPhone?
Shopify POS natively integrates with 1D and 2D Bluetooth wireless scanners that support HID (Human Interface Device) keyboard wedge mode, including Socket Mobile S700 / S740, Zebra DS2208, and Tera wireless scanners. When a barcode is scanned, the device inputs the SKU directly into the POS search field, instantly adding the item to the customer's cart.
Are my Shopify product catalog SKUs or wholesale price lists uploaded to your servers?
No. UniversalCodeMaker operates entirely inside your local web browser. Your private product names, vendor SKUs, inventory counts, and retail prices are processed locally using client-side JavaScript. No data is transmitted across the internet, logged in databases, or stored on external servers.
