When a different code fits better
These are the codes most often confused with the main answer. Pick by the activity that earns most of your revenue.
| Code | Title | Use it if |
|---|---|---|
| NAICS 561740 | Carpet and Upholstery Cleaning Services | you only clean carpets and upholstery |
| NAICS 561790 | Other Services to Buildings and Dwellings | you mainly pressure-wash building exteriors, decks or fences |
| SIC 81229 | Other building and industrial cleaning activities | you do specialist cleaning such as exterior walls or industrial machinery |
| SIC 96010 | Washing and (dry-)cleaning of textile and fur products | you only clean carpets |
Good to know
Residential maid services and commercial office cleaning share the same code in both systems, so you don't need separate codes to do both.
You can list more than one code. Companies House accepts up to four SIC codes, and SAM.gov lets you add several NAICS codes, with one marked as primary.
What the code affects
- SBA programs and federal contracts: your NAICS code sets the size limit you must stay under to count as small. Check your size.
- SAM.gov registration: contracting officers search by NAICS, so list every code you can deliver work under.
- Companies House: your SIC code appears on the public register and in your confirmation statement.
