Manufacturer serial numbers for product tracking
Manufacturer serial numbers (MSN) are unique identifiers that help track items and enable services such as warranties. Keep reading to learn everything you need to know about MSN numbers.

An MPN, or Manufacturer Part Number, is a unique alphanumeric code assigned by a manufacturer to identify a specific product or component within their inventory. Learn where and how to use them.
In the world of manufacturing and supply chain management, effective product identification is essential for streamlined operations and successful business transactions. One crucial element in this process is the manufacturer part number.
This blog post delves into the world of manufacturer part numbers, exploring what they are, why they are important, and how they are utilized across industries.
We’ll uncover the essential role MPNs play in product identification, inventory management, procurement, and supply chain coordination. By the end, you’ll have a comprehensive understanding of MPNs and their impact on optimizing your manufacturing and distribution processes.
A manufacturer part number (MPN) is a unique alphanumeric code assigned by a manufacturer to identify a specific product or component. It is used primarily for part tracking in inventory management, supply chain operations, and ordering purposes. These are often visible on the product label or even etched directly into the item itself.
The manufacturer number serves as a reference that distinguishes a particular item from others in the manufacturer’s product line or inventory.
The format and length of an MPN can vary depending on the manufacturer. It may consist of letters, numbers, or a combination of both. Some include additional information such as version numbers, revisions, or product variants. These codes help ensure accuracy and precision in identifying and sourcing the correct item.
Manufacturer part numbers are widely used across industries, including:
Manufacturer part numbers facilitate effective communication and coordination between suppliers, distributors, and customers when searching for, ordering, or replacing specific parts or products.
Manufacturer part numbers are important for several reasons, including:
Let’s cover these in more detail.
MPNs uniquely identify a specific product or component manufactured by a company. With numerous products in the market, having a distinct identifier helps avoid confusion and ensures the accurate identification of the desired item.
MPNs play a crucial role in tracking and managing inventory for manufacturers, suppliers, and distributors. By associating each product with a unique manufacturer number, it becomes easier to monitor stock levels, reorder items, and prevent stockouts or overstock situations.
MPNs enable efficient communication and coordination within the supply chain. When suppliers and manufacturers use standardized MPNs, it becomes simpler to exchange information, place orders, and ensure the correct products are delivered to the right locations.
In cases where a specific product is unavailable or discontinued, MPNs help identify suitable substitutes or compatible replacements. By referencing the MPN, customers or suppliers can find alternative options that meet their requirements.
MPNs are often referenced in warranty information and service manuals. When customers need to request warranty support or seek service for a specific product, providing the MPN ensures accurate identification and helps streamline the repair or replacement process.
MPNs can be used for cross-referencing and compatibility checks between different manufacturers’ products. In industries where components need to work together, such as electronics or automotive, MPNs facilitate the identification of compatible parts from various sources.
Overall, MPNs streamline inventory management, enhance supply chain efficiency, and simplify product identification, ultimately contributing to improved customer satisfaction, faster order fulfillment, and smoother operations within the manufacturing and distribution processes.
Manufacturer part numbers (MPNs) are used in various ways across different industries and sectors. Here are some common uses of MPNs:
Let’s move on and see what alternatives there are to manufacturer numbers.
While manufacturer part numbers are widely used and standardized in many industries, there are alternative identification systems and approaches that serve similar purposes, like:
UPCs, a type of barcode, are widely used in retail and distribution settings. They consist of 12 parallel lines encoded with product information. UPCs are scanned at point-of-sale or during inventory management to identify products quickly. While they don’t provide as much specific information as MPNs, they serve as unique identifiers for tracking and inventory purposes.
ISBNs are specific to books and serve as unique identifiers for publications. They are widely used in the publishing industry to identify and track books, ensuring accurate inventory management, sales tracking, and library cataloging.
Serial numbers are unique identifiers assigned to individual product units during manufacturing. Serial number tracking is mostly used in electronics, appliances, and automotive industries to track specific units and enable product warranties, services, and recalls. Serial numbers provide a unique identifier for each item, allowing manufacturers and customers to trace its history and identify specific units.
Some industries have their own specific coding systems tailored to their needs. For example, national stock numbers (NSNs) are used in the defense industry to identify and track military equipment and supplies. Similarly, unique device identifiers (UDIs) are used in the healthcare and medical device industry to provide unique identification for medical devices.
In some cases, manufacturers or suppliers use their own internal part numbering systems to identify products. These custom part numbers may be specific to a particular company and not standardized across the industry. While they may lack universal recognition, they serve the purpose of unique identification within the organization.
It’s important to note that the use of MPNs is quite prevalent and widely accepted in various industries due to their standardized approach and compatibility across different organizations. However, in specific contexts or industries, alternative identification systems may be employed to meet the unique requirements of those sectors.
