What is a transfer agent?
A transfer agent or registrar is an entity that keeps records of the publicly traded outstanding stock certificates of a publicly-held company and the name of the person to whom it is registered. Please note, however, that the transfer agent does not maintain records of shares bought and sold through brokerage accounts and held in "street name." Those records are maintained by the specific brokerages through whom shares are bought and sold.

What kind of services does a transfer agent provide?
If you are a registered shareholder, you should contact the transfer agent to, among other things, change your address, transfer ownership of your shares, and file a lost or missing stock certificate request.
If you own shares through a brokerage firm, you need to contact the brokerage firm directly for services.
