Codes

Hi, I hope. you can help.. So I have an e-commerce business that I source my products from Amazon (I’m not an Amazon seller). I’m using Magento2.. Im looking for a way to add manufacturer barcodes or supplier codes or product code from Amazon onto my Magento listing so that when a product arrives, dispatch doesn’t have an issue recognising what the product is & who the customer is.. So my flow is I procure the product, its sent to UK warehouse, repacked into boxes & then sent to me.. At the moment Im facing an issue where products arrive & I have no way of knowing what it is but if I could scan the code it would match up with previous orders and then at least I can work from there
