Welcome to the Collin County Clerk's Marks, Brands and Tattoos Online!
Texas, the only state to allow registration at the county level, requires anyone who owns livestock to mark, brand or tattoo their animals. For the first time in Texas history, livestock owners/agents are now able to register their marks, brands and tattoos using our all new online application.
To get started, go to the
Marks, Brands and Tattoos homepage and click Register. Enter your name and address then create a user name and a password. Once you have created your user profile, you can register your livestock mark, brand and/or tattoo with just a point and click. Your fees will be calculated as you go through the application process.
After you submit your registration you will receive a confirmation email which will consist of the information you entered in the application. Then visit us in our McKinney office located at 2300 Bloomdale Road, Suite 2106. Bring your confirmation email and your valid government issued photo ID. The clerk will verify your mark/brand/tattoo and collect the fee.
If you prefer to register in person, please visit our McKinney location. We have public access computers and highly trained staff to assist you with your registration.
For more information about our online registration process call us at 972-548-4185 or email us at
