What is NAICS?
The North American Industry Classification System, or NAICS (pronounced “nakes”), is the standard US federal statistical agencies use to classify businesses by their main economic activity. It was developed together with Canada and Mexico so that economic data can be compared across the three countries, and it replaced the older Standard Industrial Classification system. You can read a neutral overview on Wikipedia.
Codes range from two digits for broad sectors up to six digits for specific national industries. Each extra digit makes the category more precise, so a six-digit code is the most detailed level used in the United States.
How the 522110 NAICS code breaks down
Reading a NAICS code from left to right moves from the general to the specific.
| Digits | Level | Meaning |
|---|---|---|
| 52 | Sector | Finance and Insurance |
| 522 | Subsector | Credit Intermediation and Related Activities |
| 5221 | Industry group | Depository Credit Intermediation |
| 522110 | National industry | Commercial Banking |
The word “depository” is key. These institutions fund their lending mostly with deposits from customers, rather than by raising money in other ways.
Which businesses use code 522110?
The code is for institutions whose primary business is taking deposits and lending money. That includes national and state-chartered commercial banks that offer checking and savings accounts, personal loans, mortgages and business lending.
- Commercial banks that take deposits and lend to individuals and companies
- Banks offering checking and savings accounts plus mortgage or business loans
- Banks with branches, online-only operations or both
Some related institutions sit under neighbouring codes, so do not guess. The table below shows examples, but always confirm the definition and the current edition on the official site.
| Type of organisation | Typical NAICS area |
|---|---|
| Commercial bank | 522110 Commercial Banking |
| Credit union | 522130 Credit Unions |
| Savings institution | Separate depository code (check the current edition) |
| Offices of bank holding companies | 551111, in the Management of Companies sector |
| Mortgage or consumer lender (non-depository) | Other 522 codes, such as 5222 or 5223 |
When do you need the 522110 NAICS code?
Businesses, regulators and analysts use NAICS codes in many situations. A bank or a related provider might need to quote 522110 on:
- Government registrations and contract bids
- Business loan, grant or insurance applications
- Market research and industry reports
- Tax and regulatory filings that ask for a principal business activity
- Business database listings and credit profiles
If you run a business that serves banks, such as software, consulting or marketing, use the code for your own activity, not the bank’s. Selling to banks does not make you a bank.
How to confirm the right code step by step
- Go to the US Census Bureau NAICS website.
- Search by keyword or enter 522110 directly.
- Read the full definition, the cross-references and the list of illustrative examples.
- Compare it with nearby codes if your business is not a pure commercial bank.
- Check which edition of NAICS the form you are completing expects.
- Use the same code consistently across your official records and keep notes on why you chose it.
If a government form asks for a code and you are unsure, ask the agency or a qualified adviser. Choosing the wrong classification can cause delays or incorrect treatment, for example in size standards or statistical reports.
Primary activity and why classification matters
Organisations are generally classified by their primary activity, which means the activity that brings in the most revenue or best describes what the establishment does. A company with several lines of business should usually pick the code that fits its main source of income. Agencies such as the US Small Business Administration use NAICS codes to apply size standards, which is a practical reason to choose carefully and keep records supporting your choice.
Statistical agencies also use these codes to measure employment, output and wages by industry. When you see a report on the banking industry, it is usually built from establishments sharing a code like 522110. Classification schemes show up in many fields, not only finance. For example, our explainer on RN vs LVN scope of practice shows how clear category definitions shape who can do what in healthcare.
NAICS revisions
The system is reviewed and updated about every five years, with recent editions published in 2017 and 2022. Some codes are merged, split or renamed, and a few are deleted. A form from a different year might use an older code, so check the edition and, if needed, a concordance table that links old and new codes on the Census site.
Common mistakes to avoid
- Assuming every lender uses 522110. Non-depository lenders and credit unions have different codes.
- Using a code from an old article without checking the current edition.
- Choosing a code that sounds impressive instead of one that reflects revenue.
- Switching codes between forms without a reason.
A good habit is to write down the code, the edition year and the date you checked it. If an agency later asks why you chose it, you can point to the official definition and your reasoning. This record-keeping takes a minute and avoids confusion when forms are renewed or audited.
