Should Acronyms Be Capitalized?

Acronyms and initialisms are capitalized.

Should all letters in an acronym be capitalized?

Typically, acronyms and initialisms are written in all capital letters to distinguish them from ordinary words. (When fully spelled out, the words in acronyms and initialisms do not need to be capitalized unless they entail a proper noun.) ... Unlike acronyms, however, initialisms are pronounced as a series of letters.

How do you write an acronym?

Always write out the first in-text reference to an acronym, followed by the acronym itself written in capital letters and enclosed by parentheses. Subsequent references to the acronym can be made just by the capital letters alone.
