Should i tell the post office about an expunged felony?

I applied to the post office for a job. I have a felony conviction on my record that was expunged. Do I have to tell them about this?

you do have to tell them these things! but if u want a job...dont tell them!...some jobs look you up to see if u had trouble with the law soooo......they might not ask u!

goodluck n stay outta trouble!

yes you should tell them because they do back up checks on every person who applies for a job.

My understanding, if it's been legally erased, it's as if it never happened - no need to mention - I certainly would not volunteer it if that's the case.
