Understanding San Antonio Postal Codes

San Antonio, Texas, is a large and dynamic city, and like most major urban centers, it utilizes a range of ZIP codes to manage mail delivery efficiently. These five-digit codes, officially known as ZIP codes (Zone Improvement Plan codes), are assigned by the United States Postal Service (USPS).

How ZIP Codes Work in San Antonio
