People selling things door to door do need a license. Please politely ask to see it. It should be on Farmington Town Hall letterhead code enforcement a green card about 3 x 5 or so and signed by the Town Administrator or Code Enforcement Officer. If you’ re not sure call the Police Department and we will verify them. There are a lot of scams out there. Remember if it seems to good to be true, it probably is. As of this date December 15, 2016 there is no one licensed with the Town.
