Why is ID considered Nominal?

Why is ID considered Nominal?

Answer

Nominal measurement is something that cannot be ordered but because we chose to use a numeric value to represent ID will it not be considered Ordinal since I can order it in ascending or descending? Or is it because ordering it does not answer any questions or mean anything?
 
I’m just a little confused as to how numeric data can be considered as Nominal.

Hi Mohammad,
 
Thanks for reaching out.
 
Yes, you’re right that numbers 1, 2, 3, 4, 5, 6, 7, etc are examples of ID and can be arranged. However, P343XJP213 is also an ID code whose arrangement is less (or not) meaningful and not universal.
 
Gender (with values male and female) can be arranged to some as male higher than female but this is not accepted by everybody.
 
The arrangement should be clear enough and universal.
 
Hope this helps.
Best,
The 365 Team
