1. General
BarcodeStack’s tools, templates, and content are provided for general use, “as is”, without warranties of any kind. This page highlights the limitations that matter most for a barcode and label service; it supplements our Terms of Service.
2. Barcode generation is not barcode licensing
- BarcodeStack converts data you enter into barcode graphics (UPC-A, EAN-13, Code 128, Code 39, QR, and others). It does not issue, register, validate ownership of, or license any number.
- Obtain authorized identifiers or a prefix through GS1 and follow its allocation rules and your retailer’s or marketplace’s identifier requirements. Do not reuse an example number as a product identifier.
- Encoding a number here does not make it valid, unique, or yours. Verify your numbering with GS1 and your retailer or marketplace before printing product barcodes.
3. Scan reliability & print quality
- Whether a printed barcode scans depends on printer resolution and calibration, media quality, ink/thermal darkness, quiet zones, contrast, size, and the scanner reading it — all outside our control.
- Direct thermal labels fade with heat, sunlight, and abrasion and are unsuitable for long-life labeling.
- Always test-scan a printed sample before running a batch, shipping product, or sending inventory to a fulfillment center. A scan is not a standards-quality grade or proof of retailer acceptance; use a suitable verifier where required. The Terms explain limitations of liability, subject to rights that applicable law does not allow us to exclude.
4. Shipping carriers & postage
- BarcodeStack is not affiliated with UPS, FedEx, USPS, DHL, or any carrier. Our “4 × 6 shipping label” templates match common label dimensions only.
- Labels designed here are not postage and carry no shipping value. Official shipping labels and postage must be purchased from a carrier or licensed postage provider. Printing a look-alike carrier label for actual shipping — or anything intended to deceive a carrier — is prohibited and may be a crime.
5. Label sheet & printer compatibility
Sheet layouts (such as Avery® 5160/5163) and thermal sizes are design presets, not a manufacturer certification. Manufacturers change stock and printers feed imperfectly. Print a test page on plain paper and hold it against your label stock before printing on real sheets. We are not responsible for misaligned prints or wasted stock.
6. Trademarks
Avery® is a registered trademark of Avery Products Corporation. UPS®, FedEx®, USPS®, Zebra®, Rollo®, DYMO®, Amazon®, and Shopify® are trademarks of their respective owners. BarcodeStack uses these names only to describe compatibility (for example, “fits Avery 5160 sheets”) and is not affiliated with, sponsored by, or endorsed by any of these companies.
7. External links and example content
Advertising is disabled. External links are provided for context and are not an endorsement. Templates contain illustrative placeholders. Replace all sample content and verify the resulting label; an example does not establish product composition, safety instructions, identifier rights, postage or compliance with labeling rules.
8. No professional advice
Nothing on BarcodeStack is legal, regulatory, or compliance advice. Product labeling obligations (consumer goods, food, pharmaceuticals, hazardous materials, medical device UDI, and others) vary by product and jurisdiction — consult a qualified professional for your situation.
