If you operate a municipality or local government and need your NAICS code, here is your answer right away.
The primary NAICS code for general local government administration is 921120, classified under Legislative Bodies in the Public Administration sector. However, “municipality” is a broad term. Because a city or county acts as a massive umbrella for dozens of different services, the right code for your entity depends entirely on the specific administrative function you are classifying. This page covers the relevant codes so you can identify the one that fits.

What Does NAICS Code 921120 Cover?
According to the official 2022 NAICS data, code 921120 covers establishments primarily engaged in enacting laws and appropriating funds for the operation of government at the national, state, or local level.
In simple terms, this is the code for the core legislative and general administrative functions of a local government, such as a city council, county board of commissioners, or town selectmen. For municipalities, this includes:
- Enacting local ordinances, resolutions, and laws
- Holding city council, town hall, or county board meetings
- Appropriating funds for the general operations of the local government
- Establishing local public policy and strategic planning
The important distinction here is governance and legislation. This code covers the overarching decision-making and fund-appropriating functions of a city or county. It does not cover the specific operational departments that actually execute the work, like the police department or public works.
Does My Municipality Qualify for Code 921120?
Your municipality qualifies for NAICS code 921120 when classifying its central legislative and general administrative functions if:
- You operate a city council, county board, or town government
- The entity is primarily responsible for enacting laws and appropriating the municipal budget
Your municipality may not qualify for this specific code when classifying other departments, and should use the appropriate alternatives instead:
- If you are classifying the mayor’s office, city manager’s office, or chief executive functions, use 921110 (Executive Offices) instead
- If you are classifying the local taxation, budgeting, comptroller, or treasurer’s office, use 921130 (Public Finance Activities) instead
- If you operate a small town where the executive and legislative duties are officially combined into a single office, use 921140 (Executive and Legislative Offices, Combined) instead
- If you are classifying the police department, use 922120 (Police Protection) instead
- If you are classifying the water or sewer utility, use 221310 (Water Supply and Irrigation Systems) instead
When classifying a local government, you never use just one code; you use a combination of codes to represent each distinct department.
Where Will You Need This Code?
Your NAICS code appears in several critical areas of municipal administration. Here is where code 921120 (and its sister codes) will be required:
- Federal Grants and Reporting. This is highly critical. When applying for federal grants—such as Community Development Block Grants (CDBG) or HUD funding—the federal government requires your NAICS codes to accurately categorize your local government entity and track how the funds are distributed.
- Census Bureau Reporting. The U.S. Census Bureau requires local governments to report their employment and financial figures broken down by these specific public administration codes to accurately track the size and economic impact of the local government sector.
- State Funding Allocations. State governments use these codes to track how they distribute shared revenues (like sales tax or gas tax collections) back to local municipalities based on their specific administrative structures.
- Financial Auditing and Bonding. Municipal bond underwriters and independent auditors (following GASB standards) use these codes to benchmark your city’s financial data against similar local governments.
- *Economic Development Planning. Local economic development councils use these codes to report regional economic data to federal agencies accurately.

Frequently Asked Questions
Why doesn’t a city just use one NAICS code?
Because a municipality is essentially a massive conglomerate of entirely different industries. A city provides police protection (a safety industry), water treatment (a utility industry), and road paving (a construction industry). The federal government requires different codes for different departments to accurately track economic data, employment numbers, and spending at a granular level.
What NAICS code does a Mayor’s office use?
The administrative operations of a mayor, city manager, or chief executive of a municipality fall under 921110 (Executive Offices). This is kept separate from 921120 to distinguish between the executive branch (mayor/manager) and the legislative branch (city council).
What if our small town combines the executive and legislative functions?
Many smaller towns and municipalities combine these duties into a single board, council, or town manager setup. In this specific scenario, you use 921140 (Executive and Legislative Offices, Combined) to account for the unified government structure.
Does code 921120 cover the city police or fire department?
No. Operational municipal departments have their own specific codes. Police protection is classified under 922120 (Police Protection), and Fire Protection is classified under 922160 (Fire Protection). Code 921120 is strictly for the administrative and legislative governance of the municipality itself.
