Manufacturing NAICS Codes List 2026
If you're building a lead list, setting paid-search exclusions, cleaning CRM records, or segmenting manufacturers by process, the NAICS code is usually where the mess starts. A food plant, a CNC machine shop, and a semiconductor fab all sit under manufacturing, but they don't buy, quote, or search the same way.
This manufacturing NAICS code lookup uses the U.S. Census Bureau 2022 NAICS structure, the 2022 NAICS Manual, and 2023 County Business Patterns establishment data. Last updated: June 3, 2026.

What counts as a manufacturing NAICS code?
The manufacturing sector is NAICS 31-33. The Census NAICS Manual defines the sector around establishments that mechanically, physically, or chemically transform materials, substances, or components into new products. That sounds tidy on paper. In sales and SEO work, it gets more practical: the code tells you whether you're dealing with a plant that processes food, fabricates metal, builds equipment, assembles electronics, or makes chemicals.
NAICS is hierarchical, according to the Census economic census guide. Two-digit sectors roll into three-digit subsectors, then four-digit industry groups, five-digit NAICS industries, and six-digit U.S. industries. For manufacturing, the sector is shown as a range because it spans 31, 32, and 33. The same Census guide says three sectors use ranges: Manufacturing 31-33, Retail Trade 44-45, and Transportation and Warehousing 48-49.
For lead generation, the six-digit code is usually the most useful level. A broad 31-33 manufacturing list is fine for market sizing, but it will waste budget if your offer only fits food processors, medical device plants, packaging converters, machine shops, or foundries. Segment first. Then write and advertise like you know what is happening on that shop floor.
NAICS sector 31-33 compared with non-manufacturing sectors
NAICS sectors 31-33 are different from agriculture, forestry, mining, retail, and wholesale trade because the primary activity is the transformation of materials into manufactured products. A manufacturing business may sell through wholesale trade or retail channels, but the establishment is classified by the activity that produces the output. That activity can include machining, machinery production, fabrication, assembly, mixing, printing, baking, converting, or another factory process listed in NAICS 2022.
SIC codes still show up in older vendor files, but current federal industry statistics use NAICS codes. The Census Bureau is the source for official NAICS 2022 classification. Third-party references such as NAICS Association can be useful for quick lookups, but they are not the authority for manufacturing activities or official federal business data.
Use the code system to analyze markets, but don't confuse it with every adjacent activity. Crop production is agriculture, a general contractor is usually construction sector 23, and mining activities such as beneficiating are not automatically manufacturing. Manufacturing establishments may produce finished or semi-finished goods, including machinery, aeronautical parts, electronics, and materials used in later assembly. NAICS is the standard used by federal statistical agencies, while turnover, wage, and establishment data are reported through separate programs.

How to use manufacturing NAICS codes for lead generation
NAICS codes are not a strategy by themselves. They are a filter. The mistake is treating every manufacturer as if they share the same production model, quote cycle, compliance burden, and buyer vocabulary. They don't.
A contract machine shop under fabricated metal product manufacturing will respond to content about tolerance stackups, drawing packages, capacity, and inspection. A food manufacturer cares about sanitation, co-packing runs, shelf life, allergen handling, and packaging. A semiconductor manufacturer works under very different capex, yield, cleanroom, and supply-chain pressures. The code gives you a starting point for the page, ad group, RFQ form, and outbound list.
For account lists, start with the narrowest six-digit code that still leaves enough companies to sell to. For SEO, map each code to the words buyers use, not just the formal Census title. For example, NAICS 332710 is Machine Shops in the Census structure file, but buyers may search for CNC machining, prototype machining, precision machining, Swiss machining, or short-run machined parts.
Largest six-digit manufacturing NAICS codes by establishment count
These are the most common six-digit manufacturing industries by establishment count in the 2023 CBP national file. High establishment count usually means a fragmented market with many small and midsize shops. That can be good for outbound and programmatic SEO, but it also means more variation in fit.

Largest six-digit manufacturing NAICS codes by employment
Employment tells a different story than establishment count. Some industries have fewer plants but much larger headcount per site. If you're selling enterprise software, automation, training, safety services, industrial staffing, or plant-level consulting, employment density can matter more than the number of establishments. The employment figures below come from Census CBP 2023.

Which manufacturing NAICS code should you use?
Use the code that best matches the primary activity at the establishment, not the broadest market you want to sell into. A company headquarters can have one profile while its plants have different profiles. That's why plant-level targeting is cleaner than corporate-only targeting when you're selling equipment, parts, maintenance, automation, staffing, or industrial services.
The Census NAICS Manual is the authority when the title alone is not enough. The BLS Industries at a Glance manufacturing page is useful when you need labor, wage, or occupation context after selecting a manufacturing sector or subsector.
Practical examples
If you're targeting machine shops, start with NAICS 332710 and then layer in search terms around CNC machining, milling, turning, inspection, and RFQ speed. If you're targeting packaging manufacturers, codes such as 326112, 322211, and 322212 may matter depending on whether the product is plastic film, corrugated paperboard, or folding cartons. If you're building a food manufacturing campaign, don't stop at NAICS 311. Bakery, dairy, meat processing, frozen food, and animal food buyers all have different proof requirements.
That is where the code earns its keep. It keeps the list honest, but the copy still has to speak to the actual job on the floor.
Manufacturing NAICS code notes for marketers and sales teams
NAICS codes work best when you pair them with buyer intent. A code can tell you the industry, but it will not tell you whether a plant is adding capacity, replacing a supplier, launching a new product, or dealing with downtime. For that, you need page-level evidence, RFQ language, job postings, facility announcements, distributor signals, and the questions buyers ask before they contact sales.
For SEO, use NAICS codes as a page-planning tool. Build pages around processes, applications, materials, certifications, industries served, and locations. The code helps prevent generic manufacturing copy. It should not replace the words engineers and sourcing teams type into Google.
For paid search and outbound, NAICS filtering helps cut obvious waste. It can also hide good accounts if your data provider classifies a multi-site manufacturer under a headquarters code. Spot-check high-value accounts before removing them from a list.
Turn manufacturing segments into quote-ready RFQs
If your site treats every manufacturer the same, buyers can tell. Build pages and campaigns around the codes, processes, and proof that match your best-fit accounts.
