part number
Catalog reference designation
A part number is an identifier—usually a combination of letters and numbers—assigned to a specific component in manufacturing, inventory, or repair contexts.
Part numbers allow precise identification when ordering replacements or tracking stock: I need the part number to order a new filter.
They appear in catalogs, on packaging, and in technical documentation.
