If you own or operate an auto repair shop and need your NAICS code, here is your answer right away.
The primary NAICS code for a general auto repair shop is 811111, classified under General Automotive Repair in the Other Services sector. However, the auto repair industry is highly segmented by the type of work you perform. The right code for your shop depends on whether you offer full-service mechanical repairs, focus strictly on bodywork, or specialize in quick oil changes. This page covers the relevant codes so you can identify the one that fits.

What Does NAICS Code 811111 Cover?
According to the official 2022 NAICS data, code 811111 covers establishments primarily engaged in providing general automotive repair and maintenance services.
In simple terms, this code applies to traditional, full-service mechanic shops that handle a wide variety of mechanical and electrical issues under one roof. For auto repair shops, this includes:
- Engine diagnostics and mechanical repairs
- Brake and suspension system repairs
- Electrical system troubleshooting and repairs
- Transmission services and general repairs
- Cooling system, exhaust, and fuel system repairs
- Preventative vehicle maintenance
The important distinction here is general mechanical and electrical care. This code covers shops that fix the mechanical components that make a vehicle run. It does not cover cosmetic bodywork, painting, or specialized quick-lube services.
Does My Auto Repair Business Qualify for Code 811111?
Your business qualifies for NAICS code 811111 if:
- You operate a general auto repair garage or mechanic shop
- Your main source of revenue comes from diagnosing and fixing a wide range of mechanical or electrical vehicle issues
- You perform multi-point inspections and general preventative maintenance alongside major repairs
Your business may not qualify if:
- You specialize in automotive body, paint, interior, or glass repair, which falls under 811121 (Automotive Body, Paint, and Interior Repair) instead
- You operate a dedicated quick-lube or oil change shop, which falls under 811191 (Automotive Oil Change and Lubrication Shops) instead
- You only provide highly specialized mechanical services (like a shop that only does transmissions or only does electrical work), which falls under 811118 (Other Automotive Mechanical and Electrical Repair) instead
- You operate a standalone tire shop or a shop that only repairs auto air conditioning, which falls under 811198 (All Other Automotive Repair and Maintenance) instead
When your business sits between two codes, always classify based on whichever activity generates the most revenue.
Where Will You Need This Code?
Your NAICS code appears in more places than most shop owners expect. Here is where code 811111 will be required:
- Environmental and Hazardous Waste Permits. This is highly critical for auto shops. Local and state environmental agencies use your NAICS code to regulate your handling of hazardous waste, such as used motor oil, transmission fluid, solvents, and batteries.
- Garage Keepers Liability Insurance. Insurance providers use this code to calculate your premiums for Garage Keepers Legal Liability (which covers customer cars in your care) and General Liability. Mechanical shops carry different physical risks than body shops.
- SBA Loan Applications. If you need financing to purchase hydraulic lifts, advanced diagnostic computers, or expand your bays, the Small Business Administration requires your NAICS code to assess your loan eligibility.
- Parts Distributor Accounts. Wholesale parts distributors (like NAPA, AutoZone, or O’Reilly) often require your NAICS code to set up your commercial trade account.
- Business Registration. Most state and local business registration portals ask for your NAICS code when you set up a new LLC, corporation, or DBA for your shop.
- Business Bank Accounts. Many banks ask for your NAICS code when opening a business checking account to ensure your business is classified properly from day one.

Frequently Asked Questions
What is the NAICS code for an auto body shop or paint booth?
If your shop’s primary work involves fixing dents, replacing panels, painting vehicles, or repairing interior upholstery and glass, your correct code is 811121 (Automotive Body, Paint, and Interior Repair). This code is separated from general repair because the materials, equipment, and liability risks (like paint fumes and bodywork warranties) are entirely different.
What if my shop only does oil changes and fluid flushes?
If your business model is built around fast, preventative maintenance like oil changes, lube jobs, and fluid top-offs without performing major mechanical repairs, you should use 811191 (Automotive Oil Change and Lubrication Shops).
Does 811111 cover auto detailing or car washing?
No. Auto detailing, car washing, and vacuuming are considered cosmetic cleaning services, not mechanical repairs. Auto detailing falls under 812192 (Car Washes) or 812199 (All Other Personal Care Services), depending on the exact services offered.
What if a customer gets into an accident and needs both engine work and body work at my shop?
If your shop handles both mechanical and body repairs, you still must classify your business based on the activity that generates the majority of your total revenue. If 70% of your shop’s income comes from mechanical repairs and 30% comes from bodywork, your primary NAICS code remains 811111.
