Do I live in the City of Webster?
US Postal Service zip code 77598 is designated as Webster, Texas with the main postal facility located at 17077 North Texas Avenue in the City of Webster. This post office services all of the City of Webster and certain areas of Houston, League City, Friendswood, and unincorporated Harris County. Because of the 77598 zip code, any mail being delivered in this service area will carry an address of Webster, TX, even if the location is not actually within the city limits of Webster. In fact, the Webster, TX zip code area is much larger than the actual City of Webster. This can cause confusion for people who reside in certain parts of the 77598 zip code service area. This is particularly true for certain areas north of West Bay Area Boulevard, which are in the City of Houston, and other areas West of IH-45, which are in unincorporated parts of Harris County. We hope that the attached interactive map helps to clear up some of this confusion. Select the area where you live, or work, and you will find the appropriate jurisdiction. If you are still not sure if your residence or business is in the service area for City of Webster Police, Fire, EMS, or other needs, please call the Webster Police Department Records Division at (281) 316-4170, and someone can help you determine which first responder agencies service your area.
