A business using a part will often use a different part number than the various manufacturers of that part do. This is especially common for catalog hardware, because the same or similar part design (say, a screw with a certain standard thread, of a certain length) might be made by many corporations (as opposed to unique part designs, made by only one or a few).
An early 1950s transistor using the precursor to the EIA/JEDEC part numbering system. The origin of JEDEC can be traced back to 1944, when the Radio Manufacturers Association (RMA), and the National Electrical Manufacturers Association (NEMA) established the Joint Electron Tube Engineering Council (JETEC) to coordinate vacuum tube type numberings.
Direct part marking (DPM) is a process to permanently mark parts with product information including serial numbers, part numbers, date codes, and barcodes. This is done to allow the tracking of parts through the full life cycle. The interpretation of 'permanent' often depends on the context the part is used.
Typical fields in the title block include the drawing title (usually the part name); drawing number (usually the part number); names and/or ID numbers relating to who designed and/or manufactures the part (which involves some complication because design and manufacturing entities for a given part number often change over the years due to ...
A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
CAGE Codes are used internationally as part of the NATO Codification System (NCS), where they are sometimes called NCAGE Codes. CAGE codes are referenced in various databases of the NCS, where they are used along with the supplier's part number to form a reference which is held on the National Stock Number (NSN) record. This reference enables ...

Pro Electron took the popular European coding system in use from around 1934 for valves , i.e. the Mullard–Philips tube designation, and essentially re-allocated several of the rarely used heater designations (first letter of the part number) for semiconductors. The second letter was used in a similar way to the valves naming convention: "A ...
