Do colleges give a verification note when you have a college visit?

I’m going on a college visit on Friday so I will have to miss school. My high school allows two college visits a year but I have to bring a note with the date from the college to the office the next school day for verification.
Do colleges usually give you a note or do you have to request for one? If not, then when is the appropriate time to ask for it before or after the tour? Would it be a hassle for them to type one up or is this a common thing for high schools?

I would imagine you could ask the Adcom. He or she can put something on school stationary in a minute or two.
