The NSN data field has a maximum of how many characters?

The National Stock Number (NSN) data field indeed has a maximum of 20 characters. This is important because an NSN is a unique identifier used to catalog and manage supplies and equipment within the military and federal agencies. The format of an NSN consists of 13 digits: a 4-digit Federal Supply Class (FSC) code followed by a 9-digit National Item Identification Number (NIIN).

Additionally, when referencing NSN in database systems or inventory management software, up to 20 characters can be utilized for documentation, including the potential need for leading zeroes or additional formatting characters that assist in proper identification and management of stock items.

By being aware of the 20-character limit for the NSN data field, personnel can ensure accurate tagging, tracking, and retrieval of items when conducting logistics operations. This accuracy is critical for maintaining efficiency and accountability in military supply chains.
