The EIA program for assignment of Source Codes and Date Codes provides a standardized method to stamp or mark any or all products to identify the production source or vendor and to identify the year and week of production.  [The Source Code registration program is being updated.  Return here shortly for more information.]

The 2008 listing of Weekly Date Codes can be found here. This program follows the conventions defined in EIA-476-A (Source and Date Code Marking) and EIA-476-B (Date Code Marking) and follows the MIL-STD-1285 criteria.
