Williamson County GIS & Addressing staff provides the addressing for the unincorporated areas of the County as well as for several of the smaller incorporated Cities.

In addition, the staff maintains the master address database that drives the 9-1-1 telephone system for the entire County.

If you need to obtain an address (to get telephone service, utility hook ups etc.) please contact the Addressing Staff.

Your contact options are:
Web: Request Page (you may still need to speak with staff)
Phone:  (512) 943-3707
Office: 301 SE Inner Loop, Georgetown, Suite 107
Directions and Locaton Map

This tool allows you to search for all valid addresses at the time of the data load (the data is updated approximately once per month). If you need the most current, up-to-the-minute data, please contact us.

You can use this site to print a letter certifying your address.
