If you own or operate an administrative services business and need your NAICS code, here is your answer right away.
The primary NAICS code for general office administrative services is 561110, classified under Office Administrative Services in the Administrative and Support and Waste Management sector. However, there is a very distinct line between doing the actual day-to-day administrative work and advising a company on how to improve their administration. This page covers the relevant codes so you can identify the one that fits.

What Does NAICS Code 561110 Cover?
According to the official 2022 NAICS data, code 561110 covers establishments primarily engaged in providing a range of day-to-day office administrative services, such as secretarial, clerical, and receptionist services.
In simple terms, this code applies to businesses that perform the actual back-office operational tasks for other companies. For administrative service businesses, this includes:
- Virtual assistant services and remote executive assistants
- Providing temporary or contract receptionists and secretaries
- General office management and scheduling
- Data entry, word processing, and document preparation
- Telephone answering and call routing services
- Managing mail, filing, and basic bookkeeping tasks
The important distinction here is execution of daily tasks. This code covers businesses that roll up their sleeves and do the ongoing clerical work, rather than analyzing how to restructure a company’s administrative department.
Does My Administrative Business Qualify for Code 561110?
Your business qualifies for NAICS code 561110 if:
- You provide day-to-day clerical, secretarial, or virtual assistant services to clients
- Your main source of revenue comes from executing routine office tasks on behalf of other businesses
- You operate a temp agency or service that specifically supplies administrative and office support staff
Your business may not qualify if:
- You provide high-level strategic advice on how to reorganize or improve a company’s administrative operations, which falls under 541611 (Administrative Management and General Management Consulting Services) instead
- You provide general physical cleaning or janitorial services for offices, which falls under 561720 (Janitorial Services) instead
- you provide specialized facilities management services (like building maintenance or landscaping), which falls under 561210 (Facilities Support Services) 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 business owners expect. Here is where code 561110 will be required:
- Federal Contracting via SAM.gov. Government agencies frequently outsource administrative support, data entry, and secretarial functions. To bid on these contracts, you must be registered on SAM.gov under this exact code.
- Professional Liability Insurance. Insurance providers use this code to calculate your General Liability and Professional Liability (Errors & Omissions) premiums. If you accidentally delete a client’s critical database or miss a crucial scheduling deadline, you need the right coverage.
- SBA Loan Applications. If you need financing to hire more virtual assistants, upgrade your software infrastructure, or expand your office space, the Small Business Administration requires your NAICS code to assess your loan eligibility.
- Business Registration. Most state and local business registration portals ask for your NAICS code when you set up a new LLC, corporation, or DBA.
- Tax Filings and Compliance. Federal and state tax agencies use NAICS codes to categorize businesses for statistical reporting and compliance monitoring purposes.
- Business Bank Accounts. Many banks ask for your NAICS code when opening a business account to ensure your business is classified properly from day one.

Frequently Asked Questions
What is the difference between 561110 and 541611?
This is a very common point of confusion. Code 561110 is for doing the work (like a virtual assistant answering emails, booking travel, and entering data). Code 541611 is for consulting on the work (like a management consultant coming in to analyze a company’s workflow and recommending new administrative software). If you are executing daily tasks, you use 561110. If you are giving strategic advice, you use 541611.
Does 561110 cover a virtual assistant business?
Yes. Whether your administrative assistants work on-site at a client’s office or remotely from their own homes, the nature of the work is the same. Virtual assistant businesses perfectly fit under 561110 (Office Administrative Services).
What if my administrative business also does basic bookkeeping?
If you provide general administrative services alongside basic bookkeeping tasks (like tracking expenses or paying bills), you generally still use 561110. However, if your business is strictly a dedicated accounting or tax preparation firm, you should use codes under 5412 (Accounting, Tax Preparation, Bookkeeping, and Payroll Services).
Does this code cover a temp agency that supplies administrative workers?
Yes. If your primary business is recruiting and supplying temporary receptionists, clerks, or data entry staff to other companies, the government classifies this under 561110 (Office Administrative Services) rather than a general staffing code, because of the specific nature of the workers being provided.
