What It Means When CT Corporation Is the Registered Agent
When you look up a company on the California Secretary of State website and see CT Corporation System listed as the agent for service of process, it means that company has hired CT to receive legal documents on its behalf. CT Corporation is one of the two largest registered agents in the country, representing over 750,000 entities in California.
As a registered agent, CT Corporation is legally authorized to accept service. When a process server hands documents to a CT employee during business hours, that constitutes valid personal service on the corporation itself. The company cannot later claim it was not properly served.
CT Corporation’s Sacramento office is at 555 Capitol Mall, Suite 1150. This is the Plaza 555 building in downtown Sacramento, on the 11th floor. We serve documents here regularly and are familiar with the office, the building security procedures, and the staff who accept service.
You may also see entities listing C T Corporation System (with a space between C and T), or the older name Prentice Hall Corporation System. Both resolve to the same CT Corporation office.

Frequently Asked Questions
How do I know if CT Corporation is the registered agent for the company I need to serve?
Search the California Secretary of State business database at bizfileonline.sos.ca.gov. The entity’s filing will list the designated agent for service of process and their address.
What if the filing says Prentice Hall Corporation System?
Prentice Hall was acquired by Wolters Kluwer and merged into CT Corporation. Service for Prentice Hall entities is now accepted at the CT Corporation office at 555 Capitol Mall.
What if the filing says C T Corporation System with a space?
That is the same company. The legal name filed with the Secretary of State includes a space between C and T, but it is the same CT Corporation office at 555 Capitol Mall, Suite 1150.
Can I serve CT Corporation by mail?
No. California law requires personal service on a registered agent. A process server must physically hand the documents to an authorized employee at CT Corporation’s office.
