Lot numbers must be unique to the manufacturer, even if subcontractors are utilized. Please use the guidance noted below:
- Lot number sequences comply with MIL-STD-130 (marking and identification of government property) and MIL-STD-1168C; and
- lot numbers are comprised of only Roman letters and Arabic numerals, or solely Arabic numerals (cannot contain special characters other than a hyphen); and
- only one lot number is used for each production run unless the contract specifies otherwise.
