NAICS Code for Technology Services

541512 – The primary NAICS code for technology services focused on planning, designing, and integrating computer systems (Computer Systems Design Services).
541511 – The correct NAICS code if your tech service is primarily writing or modifying custom software for clients (Custom Computer Programming Services).
541513 – The NAICS code to use if you manage or operate a client’s IT systems on-site (Computer Facilities Management Services).
518210 – The classification for tech businesses focused on cloud computing, web hosting, and data processing (Computing Infrastructure and Data Processing).

If you run a technology services business, finding your exact NAICS code—whether it’s 541512 for systems design, 541511 for custom programming, or 518210 for web hosting—can be uniquely challenging. Unlike a restaurant or a retail store, “technology services” is a massive umbrella term that blurs the lines between consulting, engineering, and software development. Because the government requires precise categorization for tax, lending, and contracting purposes, the 2022 NAICS system splits the tech industry into highly specific classifications.

Guessing the wrong one can disqualify your business from federal contracts or misprice your insurance. This guide translates the government jargon into plain English so you know exactly which code belongs on your federal forms.

What is a Technology Services NAICS Code?

A NAICS code is a six-digit number used by federal agencies to classify your business by its primary economic activity. For the technology sector, these codes are crucial because they tell lenders and government buyers exactly what kind of tech business you run.

Technology services are broadly grouped under Sector 54 (Professional, Scientific, and Technical Services) or Sector 51 (Information), depending on whether you are providing a hands-on technical service or hosting digital infrastructure. Because the risk profiles and operational models of an IT systems architect and a cloud hosting provider are drastically different, the government assigns them entirely different codes.

Primary NAICS Codes for Technology Services (and What They Mean)

Because “technology services” is so broad, you will almost always land on one of five primary codes. Here is what they actually mean in plain English:

541512 – Computer Systems Design Services

What it means: This is the code for businesses that plan, design, and integrate computer systems that combine hardware, software, and communication technologies. If your business acts as an IT architect—figuring out how to piece together servers, software, and networks to make a client’s business run smoothly—this is your code. It covers IT consulting, network design, systems integration, and hardware/software consulting. The key distinction here is design and integration, not just writing code or selling equipment.

541511 – Custom Computer Programming Services

What it means: This is the code for service-based software businesses. If a client hires you to write, modify, or test custom code to solve a specific problem, you use this code. Under this classification, you are selling your programming expertise. This is the correct code for most software agencies, app developers-for-hire, and businesses providing custom application development.

541513 – Computer Facilities Management Services

What it means: This code is for businesses that manage and operate a client’s computer systems or data processing facilities on-site. If you provide ongoing, on-site IT management—essentially acting as a client’s outsourced IT department for their physical servers and localized networks—you fall under this classification.

541519 – Other Computer Related Services

What it means: This is a catch-all code for tech services that don’t fit neatly into design, programming, or management. It covers specialized services like computer disaster recovery planning, software installation services (not development), and other miscellaneous tech support services.

518210 – Computing Infrastructure, Data Processing, Web Hosting

What it means: This is the code for the cloud. If your business provides web hosting, data processing, cloud computing infrastructure (IaaS or PaaS), or server colocation, you use this code. Note that this code falls under the “Information” sector (Sector 51), not the “Professional Services” sector. Even though it is a tech service, the government classifies hosting and data processing differently than systems design.

The Challenge of Choosing the Right Tech Services Code

The most common mistake technology companies make is automatically choosing 541512 (Computer Systems Design Services) simply because it sounds like the most comprehensive “IT” code.

However, the federal government looks strictly at your revenue model. If 80% of your revenue comes from writing custom software (541511), but you occasionally help clients design their networks, you are legally required to use the custom programming code. Alternatively, if you design a beautiful IT architecture for a client but then host their entire infrastructure in your own cloud environment, you might actually belong in 518210.

This distinction matters immensely during federal contracting. Government IT contracts are highly specific. A contract for “Systems Integration” will require NAICS code 541512, while a contract for “Cloud Hosting” will require 518210. If your SAM.gov registration doesn’t perfectly match the contract code, you won’t even get past the initial screening.

Where You Will Need This Code

Having the correct technology services NAICS code is a mandatory step in several critical business functions:

Federal Contracting via SAM.gov: Government agencies buy tech services in highly segmented ways. Your SAM.gov registration must use the exact code that matches the contracts you intend to bid on.
SBA Loan Applications: Tech startups often rely on SBA loans or lines of credit. The SBA uses your NAICS code to determine your size standard and evaluate your industry’s specific financial risks.
Business Insurance: Underwriters use these codes to price your Professional Liability (Errors & Omissions) and Cyber Liability insurance. A systems architect carries a different implementation risk than a managed service provider.
Business Bank Accounts: Many banks ask for your NAICS code when opening a commercial account to assess your business model and risk profile.
Tax Filings and Compliance: State and federal tax agencies use these codes to categorize your business for statistical reporting and to identify potential R&D tax credit eligibility.

Frequently Asked Questions (FAQ)

My tech company designs systems AND writes the custom software for them. Which code do I pick?

You must classify your business under the NAICS code that represents the majority of your total revenue. If 60% of your income comes from the actual coding and 40% comes from the systems design consulting, you are legally required to use the Custom Computer Programming Services code (541511).

Does NAICS code 541512 cover Managed IT Services (MSPs)?

It depends on what “managed” means for your business. If you are remotely monitoring and managing a client’s existing hardware/software, you are likely a Computer Facilities Management Service (541513). If you are hosting their infrastructure in your cloud, you are 518210. Code 541512 is primarily for the initial design and integration of a system, not the ongoing operational management of it.

Where does cybersecurity consulting fall?

It depends on how you deliver the service. If you are designing and integrating security architectures into a client’s network, you fall under 541512. If you are writing custom security software for them, you fall under 541511. If you are providing ongoing security monitoring of their hosted data, you fall under 518210 or 541513.
