Aurora
- Permit: Yes — a Door-to-Door Seller’s License for the business (86-227(a)), plus a picture identification card for every individual rep (86-227(b), 86-230).
- Fee: The code leaves the application, annual license and ID card fees to the director (86-233). Per the 2026 Aurora Supplemental License and Application Fees sheet, under Door Sellers: license application fee $19.00, license fee $23.00, digital ID card $23.00. The ID card expires 90 days from issue and cannot be renewed, so a new card and fee come due every 90 days (86-230(f)). On top of fees, the company posts a surety bond of $1,000.00 times the number of reps (86-229) and a sales tax deposit if it makes retail sales (86-228).
- Hours you may knock: The code sets none. Division 4 (86-226 to 86-233) has no knocking hours, and the city’s licensing page and guidelines give none either. Each rep’s ID card application must list the dates, times and routes the rep will work (86-230(b)(3)).

Denver
- Permit: Yes — a peddler’s license, and every rep gets their own.
- Fee: The city’s new-application page lists the license fee as $50. The code sets a $25.00 application fee plus the yearly peddler license fee (32-101). The city page shows the $25 application fee and a $16.50 fingerprint fee under the peddler sponsor heading, so confirm what a standard adult rep is charged at checkout.
