What is Customer Part Number

What is Customer Part Number

A customer part number is a unique identifier assigned by the customer to a specific component or part in a Bill of Materials (BoM). This part number serves as a means of effective communication and referencing between the customer and the manufacturer. Unlike manufacturer part numbers (MPNs), which are assigned by the manufacturers themselves, customer part numbers are created by the customer to identify individual products.

The purpose of using customer part numbers is to streamline the communication process and ensure accurate identification of desired parts. By assigning a unique part number to each component in the BoM, the customer can easily reference and communicate their design and material requirements to the manufacturer. This helps in avoiding confusion and ensures that the manufacturer understands the specific part being requested.
