Look at it upside down.

Unfortunately, there is nothing to use for "V", so it will not work using just numbers (That would be HILARIOUS if it did), and 4 does not always look like an upside down "h" (and it looks like a lowercase h).

Watched an old episode of Who Wants to be a Millionaire and the question was, license plate upside down spells an offensive word, 1st it should have said backwards not upside down which would've made it easier, 370H55V backwards is V55H073

ASSH0LE

Your are a 370H55V-V55H073, ASSHOLE.

A number on a license plate with a rather profane meaning...

That Prius' plate said "370H55V". I turned it over and then I knew what it really meant.
