Both are commonly used. Many document codes within the industry require a TLA (Three Letter Acronym) for the organisation, the document type, and the discipline, in addition to the project code (a 6 digit number) and another 6 digit number at the end.Network Rail. I’ve always used that. Although looking now it should be just NR.
For example, a Civils drawing could have the code "123456-NWR-DRG-ECV-000234". This is how NWR sorts out their docs on ProjectWise (those who work in the industry will doubtless know).
Other org codes exist, of course - e.g. BNU for BAM Nuttall, AEC for Aecom, PLG for Powerlines Group (SPL Powerlines' parent company), SIE for Siemens, etc.
