Yeah, they're basically "temporary" addresses if that person is filming a movie or doing a concert. You might have to do your research as some venues don't pass fanmail. Sometimes your chances are better of getting an autograph by that person than if you send it to an agency or fanmail address.

I hope my answer helped!

Hey! I'm a newbie, and just started getting interessted in fanmail.

I'm a little confused, and was wondering about Via Venue's. I think I know what they are, so I'm going to say it and I want you to please correct me if I'm wrong. Are they like temporary addresses for celebrities for like when they're at concerts and stuff? Do people send pictures there because its more likely that they'll be actually autographed instead of a copy? Sorry if it's a stupid question, but I honestly don't know. Thanks!
