    The City of Newark licenses businesses by specific enumerated category (e.g., Restaurant/Eatery, Bakery, Retail, Public Garage, Dog Kennels, Food Caterer, Dry Cleaners, etc.) through its online Business License Portal, rather than issuing one universal registration certificate to every business type. Check the City's license list for your specific business type -- some service businesses (e.g., personal training, tutoring, insurance/real estate sales, cleaning, handyman, massage therapy, landscaping, HVAC/electrical/plumbing contracting, photography, pet sitting) may not appear on Newark's enumerated license list at all. Where a license does apply, it must be displayed at the place of business and renewed per the category's terms.
