Millions of people already turn to ChatGPT every day for product recommendations. Now, with ChatGPT’s Instant Checkout integration with Etsy and Shopify, they can purchase products directly inside their chat conversations. Powered by OpenAI and Stripe’s Agentic Commerce Protocol (ACP), this new feature brings discovery and purchase together, making it easier than ever for merchants to capture demand at the source.
But while the potential for AI-driven shopping is huge, there’s a hidden challenge that could undermine this seamless experience: address accuracy. AI agents are smart at finding products, comparing prices, and completing transactions but they can’t “fix” messy or ambiguous addresses. Without reliable address data, even the best AI shopping agent can leave parcels lost in transit and customers frustrated.
How Instant Checkout works
Instant Checkout lets shoppers search and buy using natural language. Customers can describe exactly what they’re looking for, like “a backpack for work for under £50” and ChatGPT acts as a personal shopper, recommending relevant products from across the web.
Shoppers can compare prices, availability, and seller quality in one place. Merchants who enable Instant Checkout can capture orders faster, while still managing fulfillment, returns, and post-purchase communications on their own systems. Payments are handled securely via credit cards, Apple Pay, Google Pay, or Link by Stripe, and for ChatGPT Plus and Pro users, shipping and payment details can even be prefilled to speed checkout.
For merchants, this is a major opportunity: AI agents are not only discovering your products but are now able to convert those discoveries into sales. These sales will only reach the customer if the address data they rely on is correct to make the delivery.
The hidden challenge: address accuracy
Here’s the catch: AI agents cannot correct bad address data. A missing flat number, a typo in a street name, or an ambiguous postcode can instantly break the shopping and delivery flow. Large Language Models (LLMs) can hallucinate, misinterpret, or misformat addresses, leading to misrouted packages, failed deliveries, and unhappy customers.
In the example below, Gemini accepted an address without recognising that the supplied postcode had one digit wrong. Without verification, packages can be misdirected, proof that even small errors can have big consequences. In a world where AI agents handle discovery, selection, and checkout, address validation is no longer a back-office task; it’s critical infrastructure.
The solution: Equip your shopping agents with address tools built for AI
This is where what3words and Swiftcomplete come in. These tools equip AI agents to handle addresses accurately and reliably.
- Swiftcomplete instantly validates traditional street addresses before the order is processed, ensuring that any errors are caught early.
- what3words addresses can be captured within your shopping agent to provide your courier with a precise, easy-to-communicate three-word address for every 3×3 meter square in the world. This eliminates ambiguity and ensures parcels reach exactly the right location.
By integrating these solutions, AI agents can confidently recognise, organise, and verify both traditional and what3words addresses, ensuring a smooth AI-to-merchant-to-doorstep workflow. Accurate, precise addresses allow packages to be delivered smoothly to the hands of your customers.
Together, Swiftcomplete and what3words fix the AI address knowledge gap, helping merchants collect accurate addresses — to reduce delivery errors, protect customer satisfaction, and scale AI-driven commerce with confidence.
The Swiftcomplete Model Context Protocol (MCP) server makes it simple for AI developers to add instant address validation to their agents.
The future of AI shopping and verified addresses
AI shopping agents are only going to grow, and Instant Checkout shows just how quickly the landscape is evolving. But AI-driven commerce will only scale as far as the underlying data allows. Without verified, structured addresses, the promise of AI shopping (seamless discovery and instant purchase) can quickly turn into lost revenue and frustrated customers.
what3words is uniquely positioned to support this transformation. Our tools ensure AI agents can recognise, verify, and geolocate addresses accurately, whether traditional or what3words format. Address validation is no longer optional, it’s an essential part of building AI-ready commerce infrastructure.
As alluded to in OpenAI’s recent announcement, Instant Checkout will shortly be available for the millions of retailers who use Shopify. Both what3words and Swiftcomplete have apps available on the Shopify app store, allowing Shopify stores to collect accurate and precise address data.
In summary
ChatGPT’s Instant Checkout is a game-changer for merchants and shoppers alike. But as AI agents handle more of the shopping journey, reliable address data will make or break the experience. Swiftcomplete and what3words provide the tools to validate every address, enabling AI agents to convert discovery into delivery with confidence.
