Commerce is crossing a threshold, and most brands haven’t noticed.
Earlier this year at NRF Retail’s Big Show, Google introduced the Universal Commerce Protocol (UCP). The concept sounds simple.
The consequences are anything but. AI systems will increasingly be able to discover, evaluate, and purchase products on behalf of consumers.
This is the beginning of agentic commerce. And it changes everything about how products get found.
Instead of a person scrolling, searching, and comparing, software agents will do that work. They’ll analyze product data, weigh alternatives, and surface recommendations, before a consumer ever enters the picture.
This challenges a long-standing assumption about how commerce works. Products have always been designed to be understood by people.
But modern commerce systems already evaluate products programmatically across search, marketplaces, and retail platforms.
As AI systems begin to participate more directly in commerce, those systems will increasingly rely on structured product identifiers and authoritative data to interpret what a product actually is.
The product identity brands rarely think about
Every product with a UPC already has a digital identity.
The moment a GTIN or UPC is issued through GS1, that product enters the digital infrastructure of commerce. Retailers reference it, marketplaces match listings to it, and supply chains rely on it to track products across systems.
What most brands do not manage deliberately is the data attached to that identity.
Product information spreads across retailers, distributors, marketplaces, and databases. Over time those systems can hold slightly different versions of the same product.
For years this has been manageable. But as commerce systems rely more heavily on structured product data, the consistency of that identity becomes more important.
Why GS1 Digital Link is the quiet signal worth watching
GS1, the global standards body behind barcodes, is already preparing for this shift through Project Sunrise 2027.
The transition introduces a new barcode format capable of resolving a GS1 Digital Link. Rather than pointing to a product number alone, it links to structured data that machines can read and trust.
Retailers, regulators, consumers, and now AI systems, can all resolve accurate, consistent product information from a single point.
The barcode stops being a checkout tool. It becomes the foundation of a product’s digital identity.
A technical shift with a very non-technical consequence
For mid-market brands, this might feel like an infrastructure story. It isn’t. It’s a competitive one.
As agentic commerce scales, AI systems will default to trusted identifiers and clean product data. The products easiest for machines to interpret will be the products most likely to surface, compare favourably, and convert.
The transition is already underway. Most brands are still building for human shoppers.
Which leaves one question worth asking right now:
If AI agents start shopping on behalf of your customers, how clearly will they understand your products?
