United States Postal Service

Houston has 157 post office listings in this directory, and most give you a fast way in: 134 show a phone number and 146 show a website. That means you can usually call ahead or check hours online before you drive over, instead of showing up to a closed counter. Clusters sit in zip codes like 77002, 77005, and 77008, each with five entries, so if you're near downtown or the Heights you have several nearby options to compare before picking up the phone.

None of these listings carry a verified badge, and this category has zero sponsored spots active right now. Any paid slot that appears down the line will wear a Sponsored tag so you know exactly which entries paid to stand out. If you run one of these locations and spot a wrong number or an empty website field, go ahead and claim the listing to fix it yourself. That small fix saves the next Houston resident from dialing a dead line or hitting a broken page.
