NAICS Code for Auto Repair (811111)

Updated: 2026
Reviewed By: SICCODE.com Industry Classification Review Team
Note: NAICS codes are typically assigned at the establishment/location level when activities differ by address.

The primary NAICS code for auto repair businesses is 811111 – General Automotive Repair. This code covers establishments primarily engaged in general automotive mechanical and electrical repair and maintenance (diagnostics, brakes, engines, suspension, steering, and similar shop services).

If a location is primarily a body shop, glass shop, oil-change-only, or car wash, the correct NAICS code is usually different. Use the code that matches the dominant activity (largest share of work/revenue).

How to choose the correct NAICS code for auto repair

Quick rule: choose the NAICS code that reflects the location’s primary economic activity (dominant service line).

  • General mechanical & electrical repair: 811111
  • Collision, body, paint, and interior repair: 811121
  • Automotive glass replacement: 811122
  • Oil change & lubrication only: 811191
  • Car wash services: 811192

Tip: confirm “included” and “excluded” activities on the destination code page before finalizing the selection.

⚠️ Common mistake: using 811111 for businesses that are primarily collision/body shops or retail tire dealers.

Body/paint/interior repair is typically 811121. Tire dealers may be classified under retail trade when the primary activity is selling tires (installation may be secondary).

Quick mapping (what the business primarily does → common NAICS)

View mapping table
If the business primarily does… Typical NAICS Notes
Full-service mechanic shop (general mechanical/electrical repair) 811111 General repair + diagnostics + maintenance as a standard offering
Collision/body/paint/interior 811121 Body work and refinishing are classified separately from general repair
Windshield/glass replacement 811122 Primary activity is glass repair/replacement
Quick lube / oil-change-only 811191 Use when oil/lube is the primary activity (not a general shop add-on)
Car wash services 811192 Washing/detailing-first locations generally classify here

Hybrid businesses: If a shop performs both general repair and body work, classify by the activity representing the majority of output.

Best practice: keep a short internal note (1–2 sentences) stating what was selected and what was excluded for repeatability.

“Auto” businesses often include repair, retail, and transportation activities. The correct NAICS depends on the primary activity.

Automobile dealers

Dealerships are typically classified in Retail Trade (Sector 44–45), not general auto repair.

Use repair NAICS codes only when the establishment is primarily a repair facility rather than a retail dealer location.
