How to mark and identify Company Policies?

Answer:

It is not mandatory for these documents to have document ID, version number and review date. In ISO 13485:2016, in point 4.2.4 it is stated that Organization must ensure that documents are identified according to the current revision status, must prevent the unintended use of obsolete documents and must apply suitable identification to them. Therefore, how you will identify them and how you differentiate them is absolutely up to you, but you must ensure that the above requirements are secured.

According to the ISO 13485:2016, for Quality Policy it is not mandatory to have document ID and version number. However, in requirement 5.3 Quality policy, in subsection e) it is stated that Top management must ensure that it is re viewed for continuing suitability. Therefore, you have to have a date on it to know when it was last reviewed.
