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 541430 | Graphic Design Services | you mainly do visual branding and graphic design rather than building sites |
| NAICS 541810 | Advertising Agencies | websites are a small part of a full advertising service |
| SIC 74100 | Specialised design activities | you are mainly a graphic designer |
Good to know
Many web designers pick a graphic design code by mistake; the official indexes put building websites under programming.
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.
