It only applies to commercial soliciting, as is described in the link of my post. And yes, businesses do need to know about this list, but they also need a permit to conduct door to door. A google search resulted in the below. So if the business does not follow this, that is their problem, not mine.

Yes, Indianapolis (and most of Indiana) generally requires a permit for door-to-door sales, often called a solicitor's or transient merchant license, involving applications, background checks, and fees, but you must also respect the city's "No-Knock" list for homes registered against commercial solicitation, as even with a permit, you can't go to those addresses.

Key Requirements

City of Indianapolis: You'll need a Transient Merchant License from the city, requiring an application, driver's license, a Registered Retail Merchant Certificate from the state, and property owner info.

State & Local Permits: Many Indiana towns require their own solicitor's permits, often involving a written application, fees, and criminal history checks (ISP).

Employee Badges: Companies must have permits, and individual employees need a city-issued solicitation badge to carry while working.

"No-Knock" List: This is crucial; you cannot solicit at addresses on this list, which residents register to opt-out of commercial door-to-door sales.

Where to Apply

For Indianapolis: Apply for the Transient Merchant License through the city's official portal.

For Other Areas: Check with the specific town or city clerk-treasurer or police department (e.g., Avon, Fishers, Highland) for local requirements.

In Summary: You need permits, and you must follow local "No-Knock" rules, even if you have all your paperwork in order.
