QR Code for Product Packaging: What to Link and How to Print It
A QR code on your packaging is real estate that can earn you reviews, followers, and repeat buyers. Here's how to use it without creating headaches down the line.
A QR code on your packaging is one of the few opportunities you get to interact with a customer after they've already bought from you — when they're opening your product and at their most receptive. Used well, it drives reviews, social follows, repeat purchases, and builds a direct relationship outside of whatever marketplace platform you sold through.
Used carelessly, it's a dead link on packaging you can't reprint, or a compliance issue if you're selling food or supplements.
What to link to: the options ranked by usefulness
1. Review request
The highest-value use, especially for Etsy sellers and marketplace brands. Link directly to your Google review page, Etsy shop reviews, or Amazon product review page. Add a label like “Loving it? Leave us a review — it takes 30 seconds.” A customer who just opened a satisfying purchase is in exactly the right state to leave a review.
2. Care instructions
For apparel, textiles, handmade goods, or anything with complex care requirements, a QR linking to a detailed care guide (Google Doc, Notion, PDF on Drive) is more useful than printing care symbols on the tag. You can include photos, video links, FAQs. Update it without reprinting packaging.
3. Social follow
Instagram, TikTok, or Pinterest depending on your category. Work best for brands with strong visual content that customers might genuinely want to follow. The label matters here: “See how others are using this” or “Follow for new collections and restocks” is more compelling than just “Follow us.”
4. Warranty or registration page
For products with a warranty or guarantee, a QR to a simple registration form (Typeform, Google Forms, or your website) is useful. You capture the customer's email at the same time — a direct channel that doesn't depend on Etsy or Amazon.
5. Reorder or referral
Link directly to the product page with a discount code in the URL parameter. Consumables (candles, skincare, food, coffee) convert well here — the customer is using the last of the product when they encounter the QR.

Live products vs. batch products: the URL stability problem
This is the practical decision most packaging designers don't think about until they've already printed.
Live products (ongoing SKU)
If you sell a product continuously and reprint packaging regularly, you have flexibility. The URL just needs to be stable for the product's life — which is manageable. Link to a page on your website or a permanent Google Doc.
Batch products (limited run or seasonal)
If you're printing packaging for a specific batch that needs to encode at print time — say, a seasonal product or a batch with a specific lot number — plan the URL before the print run. The QR must be finalized before printing. You cannot change a QR on packaging after it's printed without reprinting. This seems obvious but trips up brands who encode a “coming soon” URL or one that changes seasonally.
Rule: The URL you encode must be live and correct at print time, and must remain valid for the expected shelf life of the product.
Print compliance: food and supplements
If you're selling food, beverages, or dietary supplements in the US, QR codes on packaging touch on FDA and FTC territory:
- FDA: Required label information (nutrition facts, ingredient list, allergens) cannot be “QR-only.” These must be printed on the physical package. A QR can supplement this information but cannot replace it. If your QR links to a full ingredient list, the key allergens still need to be on the label itself.
- FTC: If the QR links to a page making claims (health claims, efficacy claims for supplements), those claims are subject to FTC advertising rules. “Scan for more information” that leads to a page making unsubstantiated health claims is still a compliance issue.
- EU: Similar rules apply under EU food labeling regulations if you sell into Europe. QR codes cannot replace mandatory labeling information.
For handmade goods, apparel, or non-food products, these restrictions generally don't apply.
Print specs for packaging QR codes
- Minimum size: 20mm × 20mm. On most packaging, you have at least this much space on the back or bottom panel. Smaller than 20mm and scan reliability drops.
- SVG or high-res PDF. Packaging artwork goes to professional printers who need vector files. Never send a 512px PNG for packaging print.
- Dark modules on a light or white background. If your packaging has a dark background, add a white or light-colored box behind the QR code with adequate quiet zone margin.
- Test on the final substrate. Kraft paper, matte foil, and glossy laminate all print differently. Proof the QR specifically, not just the overall packaging design.
