I need to store postal codes in a database. How big should the column be?

Very important

I expect the column to be a VARCHAR2, in my Oracle Database.

US Zips are 9.

Canadian is 7.

I am thinking 32 characters would be reasonable upper limit

What am I missing?

[EDIT]
TIL: 12 is a reasonable answer to the question
Thanks to everyone who contributed.
