Licenses, permits, zoning clearance to do direct sales at people homes and in firm?

[French from 974]

Hi all!

Sory for the mistakes I do, I am not an English-speaking person.

Is it necessary to obtain licenses, permits, and zoning clearance to do direct sales at people homes and in firm premises?
I would like to do advertising campaigns in targeted locations. People will be offered an appointment for me to come around.

Thanks.

Is this question about the USA? If so the answer may vary on the state, the locality and what you are doing. I was in sales for a number of years and called on dealerships. I was not required to do anything. Now if you are going door to door then most localities seem to requires something. However I see some businesses such as Avon which don't seem to require anything.
