Sounds like a functionality you will not find in a ready to use app.
Where are those codes coming from? How is the athentication happening?
Most likely you'll need custom coding to implement this.
Hey there, Bernard!
Bo here from Shopify Support.
That is a really great question and I can see the benefits behind such a feature, giving your customers peace of mins is so important as trust is the most important currency online stores deal in. I was able to find an app called My Product Registration which would appear to do what you have described.
For example, say a customer purchases a Gibson Les Paul Standard Figured Walnut Guitar, with serial number D123CDF123. They can register this exact item on your website for peace of mind and offers further opportunities to communicate with customers with your store!
If you have any questions regarding the functionality of the app I would recommend reaching out to the developers behind it by e-mail on email@example.com.
Let me know how this goes and if there is anything else I can assist you with, I'm happy to help!
All the Best,
