One way that identifier and code have been differentiated in my experience is:

Identifier is a data surrogate for something that is of interest to the enterprise. Examples would be a Social Security number or employee identification number.

Code is one of a set of valid values that conveys a characteristic of something otherwise identified. So a market segment code might be applied to a customer who is identified by a SSN or customer identifier.

This is just one way that these concepts can be used. Polysemy is always with us!

mm2: I am trying to get a copy of the white paper draft that Mike Adcock
did explaining the differences. I thought I had retained it but am
unable to locate. Mike is now deceased.  I will send when I acquire. Thanks.
