If you own or operate a computer services business and need your NAICS code, here is your answer right away.
The primary NAICS code for computer services is 541512, classified under Computer Systems Design Services in the Professional, Scientific, and Technical Services sector. However, “computer services” is a broad umbrella term. The right code for your business depends on whether you design IT systems, write custom software, or manage networks on-site. This page covers the relevant codes so you can identify the one that fits.

What Does NAICS Code 541512 Cover?
According to the official 2022 NAICS data, code 541512 covers establishments primarily engaged in planning and designing computer systems that integrate computer hardware, software, and communication technologies.
In simple terms, this code applies to any business whose main activity is designing, building, or integrating technology systems for clients. The hardware and software can be provided by your business or sourced from third parties. This includes:
- IT systems integration and network design services
- Computer hardware and software consulting services
- Local area network (LAN) or wide area network (WAN) design and implementation
- Audio visual and IT systems integration design
- Office automation systems design
- Information management systems integration
The important distinction here is design and integration. This code is for businesses that plan and build technology systems, not for businesses that simply write the code from scratch or sell computer equipment out of a retail store.
Does My Computer Services Business Qualify for Code 541512?
Your business qualifies for NAICS code 541512 if:
- You provide IT consulting on hardware, software, or network architecture
- Your main revenue comes from planning and integrating computer systems for clients
- You act as an IT architect figuring out how to piece together servers, software, and networks to make a client’s business run smoothly
Your business may not qualify if:
- You primarily write, modify, or test custom software code for specific clients, which falls under 541511 (Custom Computer Programming Services) instead
- You manage or operate a client’s computer systems or data processing facility on-site, which falls under 541513 (Computer Facilities Management Services) instead
- You provide cloud computing, web hosting, or data processing, which falls under 518210 (Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services) instead
- You sell computer hardware or software as a retailer, which falls under 443120 (Computer and Software Stores) 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 541512 will be required:
- Federal Contracting via SAM.gov. Government agencies heavily outsource IT work. To bid on contracts for systems integration or IT architecture, you must be registered on SAM.gov under the exact code that matches your service.
- SBA Loan Applications. The Small Business Administration requires your NAICS code on all loan applications. Lenders use it to assess your industry risk profile and determine eligibility for specific financing programs.
- Business Insurance. Insurance providers use your NAICS code to classify your business type and calculate your Professional Liability (Errors & Omissions) and Cyber Liability premium rates. Systems integrators carry high liability risk for the architecture they design.
- Business Registration. Most state and local business registration portals ask for your NAICS code when you set up a new business entity for the first time.
- 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 NAICS code if I write custom software for clients?
If your computer services business primarily writes, modifies, or tests custom code to solve a specific client problem, you should use 541511 (Custom Computer Programming Services). You only use 541512 if your primary focus is designing and integrating the overall hardware and software systems.
What if I manage a client’s IT systems remotely or on-site?
If your main service is operating, managing, or monitoring a client’s existing IT infrastructure on an ongoing basis, your code is 541513 (Computer Facilities Management Services). Code 541512 is primarily for the initial design and integration of a system, not the long-term operational management of it.
Does this code cover selling computer hardware to my clients?
No. Even if you are an IT consultant, if your primary revenue comes from purchasing computer hardware and reselling it to clients at a markup, you are acting as a retailer or wholesaler. You would fall under Retail Trade (443120) or Wholesale Trade (423430), depending on who you are selling to. NAICS code 541512 is a professional service code, not a sales code.
What is the difference between 541512 and 541519 (Other Computer Related Services)?
Code 541512 is for designing and integrating complete systems. Code 541519 is a catch-all for miscellaneous computer services that don’t involve systems design, custom programming, or facilities management. This includes things like computer disaster recovery planning, software installation services, or data recovery services.
