Part numbers identify specific product models, SKUs, or catalog numbers. Each product can have multiple part numbers, and each part number can have tags (labels for segments of the number) and notes (warnings or annotations).

On the Product Details page, part numbers appear in the right sidebar as clickable badges. Each segment of a hyphenated part number is shown separately. Small colored dots indicate if a part number has notes (amber) or tags (gray).

When you use "Get Specs with AI", the system analyzes the cutsheet PDF and extracts part numbers with their specifications. Each extracted part number shows a confidence level (high, medium, or low) and suggested tags for each segment. You can review and edit these before accepting.
