FAQ

Can I use "California" in my LLC name?

Yes. No restriction on state names. "California Digital Marketing LLC" is acceptable.

Does a clear search guarantee my name will be accepted?

No. The SOS makes the final determination during filing. However, a thorough search significantly reduces rejection risk.

How do I check for trademarks?

Search the USPTO TESS database (federal) and the California SOS trademark registry (state). LLC registration does not provide trademark protection.
