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 541199 | All Other Legal Services | you provide other legal services such as process serving |
| NAICS 541120 | Offices of Notaries | you run a notary office |
| SIC 69101 | Barristers at law | you are a barrister |
| SIC 69109 | Activities of patent and copyright agents; other legal activities n.e.c. | you provide other legal services |
Good to know
Paralegal services without a lawyer use the "other legal services" codes.
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.
