Liability Co.," "Limited," "L.L.C.," "LLC," or "Ltd." The word "Limited" and "Company" can be abbreviated as "Ltd." and "Co." respectively.

To reserve an available name for 120 days, file an Application for Reservation of Name by postal mail. The filing fee is $60.

Refer to the Business Entity Tax webpage for detailed information.
