Barcode Stickers and QR Code Labels for Products: Print Specs That Scan

Quick answer: A barcode sticker scans when its size, color and placement are right: UPC-A prints between 80% and 200% of nominal size, in black bars on white, with clear space on both sides and never on a seam or tight curve. Transfer305 prints full-color UV-DTF product labels with the code you supply built in, from about $0.13 for a 1.75 x 1.25 in UPC sticker ($0.06 per square inch by size), with no minimum order.

A product label with the code built in is a UV-DTF sticker. UV-DTF stickers are also searched as DTF stickers. Your brand artwork and the barcode or QR code print together as one piece and go onto smooth, hard bottles, jars, tins and devices by hand, with no heat press.

Does your product need a barcode, a QR code or both?

Most products carry one code or both:

• A UPC barcode for retail checkout and marketplaces. It identifies the product at the register.
• A QR code that opens a page you control: instructions, ingredients, reorders or a video.

Both work better when the label is designed around them from the start. The UPC specs below come from GS1 guidance, so you can lay out custom barcode stickers and QR code labels that are ready to test.

Where do UPC barcodes come from?

Retailers and marketplaces "often require UPC barcodes that come specifically from GS1." You create your UPCs with your own GS1 Company Prefix. Transfer305 prints the code you supply and does not issue UPC numbers.

What size should a barcode sticker be?

A UPC-A barcode can print from 80% to 200% of nominal size, and the GS1 US default file at 100% is 1.644 x 1.153 in, including the numbers. The rules below keep the code readable at any size in that range.

Scaled from the 100% default file, the allowed range works out to these file sizes:

How to choose a UPC barcode label size: start from the 100% file. A 1.75 x 1.25 in label is just larger than the 1.644 x 1.153 in default, so the code fits with a small margin. If you shrink the code toward 80%, scale the whole symbol evenly and never cut the bars shorter. Keep artwork out of the quiet zones on both sides.

On a round bottle or jar, place the code on the straightest part of the body, and switch to the ladder orientation when the curve is tight.

Which colors and finishes will scan?

Contrast does the work. Follow these rules for the code area:

• Use black bars on a white background. GS1 guidance notes that matte black on white gives the highest contrast.
• On clear bottles and jars, print an opaque white area behind a black code. With UV-DTF, the white block and the code print together on one sticker.
• Avoid red bars. POS scanners cannot read red.
• Avoid high-gloss surfaces that reflect light across the code.
• Keep patterns and photos out from under the bars.

The rest of the label can be as colorful as your brand. Only the code area needs to follow these rules.

Can a QR code replace the UPC?

Not yet for retail checkout. Under GS1 US Sunrise 2027, retail POS systems are being prepared to scan 2D barcodes, like QR codes with GS1 Digital Link, by the end of 2027. The 1D UPC remains required during the transition, so print the UPC for checkout and add a QR code for everything else.

For QR code labels, keep a quiet zone of four modules on all sides, and use error correction level M, the common default. Our guides to QR code stickers for business and QR code artwork and clear space cover sizing and clear space in more depth.

What do barcode labels with the code built in cost?

Instead of a plain barcode sticker next to your label, build the code into the label itself. At $0.06 per square inch by size, each option is easy to price:

A 23 x 24 in UV-DTF gang sheet ($22.49) holds about 35 of the 3 x 4 in labels, roughly $0.64 each, and every label on the sheet can carry a different product and code. That count is an estimate based on 1/4 in spacing. Order single designs with UV-DTF by size.

Need a different code on every item? Lay the labels out yourself and upload the finished sheet; we print exactly what you send. Our comparison of UV-DTF and printed labels for variable details explains that route. Tracking tools and devices rather than products? See custom equipment decals and asset labels.

How do you test barcode stickers before a full run?

Start with a single label by size. Apply it to the actual product: clean and dry a flat area, place the label, rub over the whole design with firm pressure and draw the carrier off slowly. Then scan it with several phones and, if you can, a retail scanner.

For retail compliance, check the printed code with a barcode verifier before you order the full run. A single sample label by size costs well under a dollar, so test before you commit.

How do you order barcode stickers in quantity?

1. Get your UPC numbers through your GS1 Company Prefix, and create your QR code.
2. Place the final code in your label artwork at the right size, with its quiet zones clear. Our artwork requirements cover file setup.
3. Send the artwork to sales@transfer305.com, or order a single label by size to test.
4. Apply and test-scan the sample on your product.
5. Order the full run by size, setting the quantity for each design, or on a gang sheet.

Frequently asked questions

Where do I get UPC barcodes for my product?

Through GS1. Retailers and marketplaces often require UPCs that come from GS1, and you create them with your own GS1 Company Prefix. Transfer305 does not issue UPC numbers: we print the code you supply, so get your numbers before you order and place the final code in your label artwork.

What size should a UPC barcode be?

UPC-A can print from 80% to 200% of nominal size. The GS1 US default file at 100% is 1.644 x 1.153 in, including the numbers, so a 1.75 x 1.25 in label fits it with a small margin. Scale the whole symbol evenly and do not shorten the bars to fit a small label.

Can barcodes go on curved bottles?

Yes, away from seams, edges and tight curves. Place the code on the straightest part of the body. On a bottle with a small radius, turn the code so the bars run horizontally (ladder orientation), then test-scan the applied label before you order the full run.

What colors work for barcodes?

Black bars on a white background. GS1 guidance notes that matte black on white gives the highest contrast. On clear packaging, add an opaque white area behind the code, which prints with the code on one UV-DTF sticker, and never use red bars, which POS scanners cannot read.

Can I put a QR code instead of a UPC?

Not yet for retail checkout. Retail POS systems are being prepared to scan 2D barcodes by the end of 2027, and the 1D UPC remains required during the transition. Print the UPC for checkout and add a QR code for everything else, such as instructions, ingredients, reorders or a video.

How much do barcode stickers cost?

UV-DTF by size is $0.06 per square inch. A 1.75 x 1.25 in UPC sticker is about $0.13, a 1.5 x 1.5 in QR label about $0.14, and a full-color 3 x 4 in label with the code built in $0.72. There is no minimum, so set the quantity you need for each design.

Order barcode stickers and QR code labels

Order by size and set your quantity per design, or send your label artwork with the final code to sales@transfer305.com. Test a single label, then order the full run. No minimum.
