Williamson County is the northern Austin metro county, bordered by Travis County to the south. It has been one of the fastest-growing counties in the United States for over a decade — Georgetown, Round Rock, Cedar Park, and Pflugerville have all added tens of thousands of residents, most arriving from Travis County (Austin) or from out of state. The county population exceeded 700,000 as of 2023 Census estimates.
The key routing issue for any Austin-metro search: Round Rock and Cedar Park both straddle the Travis-Williamson county line. Specific addresses in both cities can fall in either county. A Round Rock address in Travis County routes to Travis County District and County Clerk; the same zip code in Williamson County routes to the Williamson County Clerk in Georgetown. Texas requires checking both the District Clerk (felonies) and County Clerk (misdemeanors) separately. For broader Texas context, see our Texas people search guide and our Travis County guide.

Williamson County's rapid growth has brought rapid expansion of public safety infrastructure. The Williamson County Sheriff's Office covers unincorporated areas; Round Rock, Cedar Park, Georgetown, and Pflugerville each have their own police departments. The county's relative affluence and suburban character means crime rates are below Texas averages per capita, but total booking volume has grown sharply with the population. The Williamson County Jail in Georgetown covers county-level custodial holds.

The Travis-Williamson county line runs through Round Rock — addresses south of the boundary fall in Travis County; addresses north are Williamson County. The Round Rock ZIP codes 78664, 78665, and 78681 are primarily Williamson County; 78681 has some Travis County parcels near the boundary.

The northern portion of Cedar Park is Williamson County; southern portions along Ranch Road 620 may be Travis County.

Common search scenarios
Searching by name and city in Williamson County
For Round Rock and Cedar Park searches, confirm the county for the specific address before choosing a clerk portal. The Williamson County District Clerk and County Clerk are both online with searchable case indexes. Georgetown and Pflugerville addresses are unambiguously Williamson County.
Searching for Williamson County court records
Check both the District Clerk (felonies) and County Clerk (misdemeanors) separately — they do not share a single unified portal. Texas DPS non-disclosure orders can obscure eligible misdemeanor records. If a search returns nothing for a known Williamson County resident with expected prior history, Travis County is the most likely alternative location given the relocation pattern.
When the city is unknown
A background report surfacing address history resolves the Travis vs. Williamson county question for Round Rock and Cedar Park addresses. Given that most Williamson County residents are recent arrivals, the prior address history is typically the most valuable part of the initial search.
