ZIP Codes

This guide provides a practical directory of ZIP Codes serving Bexar County, Texas. It includes standard delivery ZIP Codes as well as PO Box and unique ZIP Codes associated with the county. Each ZIP Code is listed once with its primary mailing city and ZIP Code type so users can identify the correct postal designation without duplicate city-name variations or outdated aliases.

Understanding Bexar County ZIP Codes

Most ZIP Codes in Bexar County begin with 782 and use San Antonio as the primary mailing city. Other ZIP Codes serve communities such as Atascosa, Boerne, Castroville, Helotes, La Coste, Lytle, Poteet, Somerset, Von Ormy, Adkins, Cibolo, Converse, Elmendorf, Marion, Universal City, Saint Hedwig, Schertz, and Bulverde. Military mailing areas include JBSA Randolph, JBSA Ft Sam Houston, and JBSA Lackland.

ZIP Codes are designed for mail delivery and do not define city or county boundaries. A ZIP Code may cross municipal or county lines, and the primary mailing city may differ from the incorporated city in which a particular address is located. For example, some ZIP Codes associated with Boerne, Castroville, Cibolo, Marion, Poteet, Schertz, Bulverde, and San Antonio extend across county boundaries. For property records, taxes, elections, emergency services, or other jurisdiction-specific questions, use the complete street address rather than relying on the ZIP Code alone.

Standard, PO Box, and Unique ZIP Codes

Standard ZIP Codes generally serve regular street addresses. PO Box ZIP Codes are primarily used for post office boxes and may not correspond to a normal geographic delivery area. Unique ZIP Codes are assigned to specific organizations or high-volume mail recipients. The table identifies the type of each ZIP Code so users can distinguish ordinary address ZIP Codes from special-purpose mailing codes.

Using the ZIP Code Directory

To find a ZIP Code quickly, scan the first column and then confirm the primary mailing city in the second column. The mailing city is the preferred city name associated with that ZIP Code, but USPS may recognize additional acceptable city names for some addresses. Alternate names are not repeated as separate rows in this directory.

For addresses near the Bexar County boundary, a ZIP Code may also serve locations in a neighboring county. Likewise, a San Antonio mailing address does not necessarily mean the property is inside San Antonio city limits. When exact jurisdiction matters, verify the full street address with the appropriate county, city, appraisal, election, or emergency-service agency.

Data note: ZIP Code types and primary mailing-city names follow current USPS ZIP and city conventions. Bexar County and other official jurisdiction records are used to identify ZIP Codes associated with locations in the county. ZIP Code assignments and acceptable mailing names can change, so a specific street address should be verified through the USPS ZIP Code Lookup when exact mailing information is required.
