I am working on a part search engine for company maintenance teams. We built a search engine that searches parts in real time across a dozen or so vendors (Amazon, eBay, McMaster, etc). We then leverage Chat GPT to extract data from product titles. Part number is one of the key elements we extract. Since part numbers vary greatly across manufacturers, it's difficult to throw something like a regex at it. It has done a really good job so far for data extraction.
