About Webb County
Webb County is in South Texas, alongside the Rio Grande and the international border with Mexico. Laredo is the county seat and the largest city.
The county reaches well beyond the built-up City of Laredo. Its county-wide income and housing estimates should not be treated as neighborhood-level measurements, and its Census county boundary does not depict property parcels.
What is the Webb County FIPS code?
The five-digit county FIPS code for Webb County, Texas, is 48479. The first two digits, 48, identify Texas, while the last three digits, 479, identify Webb County within the state. The county code is distinct from a postal ZIP Code.
FIPS codes are used to connect records across county-level geographic datasets. Use all five digits when searching the Census Bureau’s data. City limits, county boundaries, school districts, and postal ZIP Codes can differ.
County population, income, housing, and land area
The figures above use the American Community Survey 2020-2024 five-year estimates for population, median household income, median owner-occupied home value, median age, and poverty. The survey’s estimates have margins of error. They are not live population counts or listings of current real-estate prices.
The map boundary and land area come from the U.S. Census Bureau’s TIGERweb 2026 county geography. Population density on this page divides the ACS population estimate by mapped land area in square miles. Data vintages and survey methods can affect the comparability of figures.

Frequently asked questions
What is the county seat of Webb County?
Laredo is the county seat. A county seat is an administrative center, not a synonym for the entire county.
How can I check an address in Webb County?
Use a local government GIS or authoritative address lookup for a precise address. The What County Am I In? tool provides general location assistance, but parcel and jurisdiction decisions require official records.
Are these boundaries appropriate for property or legal decisions?
No. This interactive map is for general county reference. It should not replace parcel surveys, election maps, zoning maps, or authoritative emergency-service jurisdictions.
What happens when a Census data service is unavailable?
The interactive facts or map can show an unavailable message. We do not substitute guessed population or financial values. Review the Data and Methodology page for definitions and data limitations.
