Your NAICS code is one of the first things a lender reads. It decides whether the lender funds your industry at all, how it prices the risk, which products it offers and, for SBA loans, whether you count as small. A correct code puts your file in front of lenders with appetite for your industry. A wrong or restricted code can stop the file before anyone reads the bank statements.

How lenders use your NAICS code
Most lenders, from banks to online lenders, run four checks off the code.
| Use | What the lender does with the code |
|---|---|
| Appetite list | Compares your code to a list of industries it funds, prefers or declines |
| Pricing tier | Places your industry in a risk band that moves rate, term and advance size |
| Product fit | Routes you to term loans, lines, equipment finance or receivables products |
| Eligibility and size | For SBA loans, checks the ineligible list and the size standard for your code |
Appetite lists are written in NAICS codes because the codes are precise. A lender might fund 238220 (plumbing and HVAC contractors) but decline 238910 (site preparation) because of how equipment heavy and seasonal it is. It might take 722511 (full service restaurants) with two years in business but decline 722410 (bars) outright.
SBA ineligible industries
The SBA's ineligible list is in 13 CFR 120.110. It is defined by activity, not by code, but in practice lenders map it to NAICS codes. The main categories:
| Ineligible category | Typical NAICS codes affected |
|---|---|
| Financial businesses primarily engaged in lending, such as banks, finance companies and payday lenders | 522110, 522291, 522292, 522390 |
| Passive businesses owned by developers and landlords that do not actively use or occupy the property | 531110, 531120, 531190 when held passively |
| Life insurance companies | 524113 |
| Businesses primarily engaged in speculative activities, such as oil wildcatting | 523160, 523910, 211120 when speculative |
| Businesses that earn more than one third of gross annual revenue from legal gambling | 713210, 713290 |
| Pyramid sales distribution plans | Any code |
| Businesses principally engaged in lobbying or political activity | 541820, 813940 |
| Private clubs that restrict membership for reasons other than capacity | 713910, 813410 when restricted |
| Businesses presenting live performances or selling products of a prurient sexual nature | Varies by activity |
| Businesses engaged in any activity illegal under federal law, which includes cannabis | 111998, 424590, 459999 and others when cannabis related |
Cannabis deserves a note. Because marijuana remains illegal under federal law, SBA policy treats businesses that grow, process or sell it as ineligible, and that extends to businesses that derive revenue from serving them directly, such as dispensary landlords. Hemp that meets the federal definition is a different case.
Passive real estate is the other common surprise. A business that owns a building and leases it to its own operating company can qualify through an eligible passive company structure. A landlord that leases to unrelated tenants cannot.
Industries lenders treat as high risk
Outside the SBA list, private lenders keep their own restricted lists. These vary by lender, but the same industries come up again and again:
- Restaurants and bars (722511, 722513, 722410), for thin margins and high failure rates.
- Trucking (484110, 484121, 484230), for fuel swings and owner operator concentration. See our trucking NAICS guide.
- Construction specialty trades (238 series), for project risk and slow receivables.
- Auto dealers (441110, 441120), for floor plan exposure.
- Nonprofits and religious organizations (813 series), for revenue structure.
- Financial services such as debt collection (561440), check cashing and payday lending (522390).
- Firearms, adult entertainment, crypto and cannabis, often for reputational or regulatory reasons.
Being on a restricted list at one lender rarely means you are restricted everywhere. It means the lender pool is smaller and the match matters more.
Which codes get the best terms
Lenders like industries with steady revenue, low failure rates and assets that hold value. Codes that tend to see the widest lender appetite and best pricing:
| Industry | Example codes | Why lenders like it |
|---|---|---|
| Medical and dental practices | 621111, 621210 | High, steady collections and low default rates |
| Accounting and legal | 541211, 541110 | Recurring clients and low capital needs |
| Engineering and consulting | 541330, 541611 | Contract revenue and strong margins |
| Insurance agencies | 524210 | Renewal commissions behave like recurring revenue |
| Specialized manufacturing | 332710, 333 series | Equipment collateral and contract backlogs |
| Veterinary services | 541940 | Practice values and stable demand |
How an AI brokerage reads your code
At Levr, the code is one of the first signals the matching engine reads. It checks your code against each lender's appetite list, removes lenders that decline your industry, ranks the rest on how they price your code at your revenue and time in business, and then layers in the deal details. The result is a short list of lenders that actually fund your industry, instead of a blind submission to lenders who will decline on code alone. Start an application and the AI matches the deal to lenders that fund your code.
What to do if your industry is restricted
A restricted code narrows your options, but it does not close them. Products that underwrite an asset or a receivable care less about the industry.
| Product | Why it works for restricted industries |
|---|---|
| Equipment financing | The equipment is the collateral, so the lender looks at resale value |
| Invoice factoring | The factor underwrites your customers' credit, not yours |
| Revenue based financing | Underwritten on bank deposits and card volume |
| Asset based lines | Secured by receivables and inventory |
| Commercial real estate loans | Secured by the property |
Specialist lenders also exist for most restricted trades, including trucking, restaurants, construction and auto.
Do not pick a code to get around a restriction
Choosing a NAICS code that does not match what the business does is misrepresentation. Underwriters compare the code to your bank statements, website, invoices and tax returns. A mismatch gets caught, and once it does the application is finished with that lender. If your current code is genuinely wrong, fix it everywhere using our guide on how to change your NAICS code.
Size standards for SBA loans
For SBA loans, your NAICS code also sets the size standard you must meet, measured in average annual receipts or employees. Most applicants pass easily, and SBA 7(a) and 504 borrowers can also qualify under the alternative size standard of $20 million in tangible net worth and $6.5 million in average net income. Our page on SBA size standards by NAICS code has the details.
Questions people ask
Does my NAICS code affect my business loan?
Yes. Lenders use it to decide whether they fund your industry at all, how they price the risk and which products they offer.
What NAICS codes are ineligible for SBA loans?
The SBA bars businesses primarily engaged in lending, passive real estate investment, speculation, gambling that makes up more than a third of revenue, cannabis, and a short list of others under 13 CFR 120.110.
What are high risk NAICS codes for lenders?
Codes lenders often restrict include restaurants, trucking, construction specialty trades, auto sales, adult entertainment, firearms, cannabis, crypto, and financial services like debt collection and payday lending.
What can I do if my NAICS code is restricted?
Look at products that underwrite the asset or receivable instead of the industry, such as equipment financing, invoice factoring and revenue based financing, and work with lenders that specialize in your trade.
What NAICS code should I use for an SBA loan?
The six digit code for the activity that earns most of your revenue. The SBA uses it to check your size standard and your eligibility.
