Barcodes, explained honestly
Free guides to the confusing parts of GS1 Digital Link, Sunrise 2027, and GTINs. Useful whether or not you ever sign up for Codestamp.
- What is a GS1 Digital Link?A plain-English explainer of the web-address format for barcodes: one code that scans at checkout and opens a page on a phone.
- Do I need a QR code on my product by 2027?What Sunrise 2027 is, which categories have real legal dates, and why moving early pays off for a small brand.
- What is dual marking, and do I need it?How to print your existing UPC alongside a new 2D code during the transition, and how to lay them out without confusing a scanner.
- How do I buy a real GTIN?Where GTINs come from, what one costs, and why a cheap third-party number can get your marketplace listing rejected.
Where Codestamp fits on your label
You already own a barcode number and a UPC that scans. Keep both. Codestamp gives that same number a QR code that can do more, and nothing you paid for has to change.
Your GTIN
Your product's barcode number, bought once from GS1 ($30 for one number) and yours for good. We never sell numbers: yours is all you need.
Your UPC
The stripes every checkout reads today. It stays on your label and keeps working in 2027 and after. No rush, and no wasted labels.
Add Codestamp
Your number in a GS1-standard QR code, free on our domain or yours from $9/mo. Checked and scan-tested, so it works the first time.
Every scan
A phone opens your product page, or one we host. Newer checkouts read your GTIN. Change where it points anytime. The label stays put.
You could do it yourself. Here is what you get with us.
GS1 runs a free shared link service, and any QR generator can hold a web address. Codestamp builds the address to the GS1 format and scan-tests the code, so it is right every time. You get one place to change where every code points after printing, a hosted product page if you have none, and your own name on the code from $9/mo. Your first 3 products are free on our shared domain.
Free for your first 3 products. No credit card, no time limit.
