Here’s the secret to making the rule work: The rule applies to the sound of the letter beginning the word, not just the letter itself. The way we say the word will determine whether or not we use a or an. If the word begins with a vowel sound, you must use an. If it begins with a consonant sound, you must use a.
If the acronym starts with the sound of a vowel, you will use An before the acronym. This can be tricky because words that start with consonants can use An. Letters that are vowel-sounding and need An include X, S, R, O, N, M, L, I, H, F, E, and A.

There are some acronyms that can be pronounced as a word, like NASCAR, or just a series of letters called abbreviations, like NBC.
When the acronym can be pronounced as a word, the first letter will determine whether you use A or An before the acronym.
Choosing whether to use A or An before an acronym can be done using the abbreviation or the verbalized word. Using the abbreviation to determine which to use will sound more natural in your head and as it comes out of your mouth. This is also the case for when you pluralize acronyms.
