GS1 QR code generator
One code for a product: a GS1 Digital Link that opens like any web link on a phone, built from the same GTIN that sits under your barcode.
A GS1 Digital Link QR code stores a product’s GS1 identifier as a web address, so the same symbol works for a checkout scanner and a phone.
Style this code — colour, shape, branding, frame and output
Colour & contrastThe ink, the paper behind it, and the three eyes. Every choice is contrast-checked as you make it.
ShapeHow the squares are drawn. The three eyes are styled apart from the data, because a scanner finds the code by them.
BrandingYour mark on the code. Every picture here costs scanability — the notes say how much, and the preview is the truth.
Frame & captionA border and a line of text around the code — the "scan me" that tells a passer-by what it is for.
OutputWhat comes out of the download buttons, and what the symbol actually carries.
Print-ready PDF
A press file at the finished size: 3mm bleed, crop marks and a trim box a print shop’s checks read. The code is drawn black on white whatever the design above — how a colour prints is something only a test print can show.
A web link and a barcode identity in one symbol
A Digital Link is an ordinary HTTPS address that carries your GTIN — and batch, serial and expiry when you add them — in a form both a phone camera and GS1-aware software can read. Consumers get a page; supply-chain systems get the identifiers.
The element-string output is for industrial scanners
Switch the output and the code carries GS1 element strings with the FNC1 flag set, the form retail and logistics scanners expect. Phone cameras read it as text, not as a link — print it for the supply chain, not the shop window.
Structurally valid is not registered
Every number here is validated against the GS1 rules, check digit included. That makes it correct in structure — it does not make it yours. GTINs are allocated through a GS1 company prefix, so codes built from numbers you do not own are for internal or test use.
GS1 QR codes
Which output should I pick?
The web link, unless a scanner operator has asked for element strings. The link opens on any phone; the element string is read by supply-chain equipment.
Where does the link point?
To id.gs1.org by default, which resolves the product for GS1-aware apps. If your brand runs its own GS1-conformant resolver, enter that domain instead.
Can I add batch, serial or expiry?
Yes — each travels as its own GS1 application identifier: batch as (10), serial as (21), expiry as (17). Leave blank whatever a label does not need.
Is this the same as the barcode on my pack?
It carries the same GTIN. The retail barcode stays for the till; this code adds a scannable link for phones and a data carrier richer than the stripes.
