Get number 866 for free if you're calling from the US

Hey everyone,
Not quite sure which sub I should drop this in, so I figured I'd just post it here.

So, I need to call this number: (866) 850-4303. It’s a toll-free number within the US, but does anyone know if it's still free to call from overseas?
Anyone have any insight?
Thanks.

Anyway, I managed to figure it out myself.
By the way, does anyone know how to delete a post?

Quick question—how do I delete a post? For some reason, I have the DELETE option on my second post, but it’s completely missing from my first one.
