City of Houston — ZIP Code 77056 map
City of Houston Planning & Development publishes a dedicated
77056 ZIP boundary map based on the COHGIS database. The map is used
here for geographic context and neighboring ZIP boundaries.
City of Houston — ZIP Code reference
The City's ZIP reference identifies 77056 and city facilities located
within the ZIP, including Grady Park and The Park on San Felipe.
Uptown Houston — district information
Uptown Houston documents the area's office, residential, retail and
transportation characteristics. Its information is used to explain
why 77056 contains a mixture of property types and uses.
FCC National Broadband Map
The FCC explains that its map provides location-level information
about reported providers, technologies and maximum advertised speeds.
The FCC also recommends checking individual locations rather than
relying solely on broad geographic boundaries.
AT&T availability information
AT&T states that internet availability depends on the customer's
address and provides an address-level availability process.
Xfinity availability information
Xfinity explains that serviceability can depend on the physical
network, service-line extension and property access arrangements.
T-Mobile Home Internet
T-Mobile identifies Houston as a 5G Home Internet market and explains
that eligibility is determined by the service address and network
capacity. T-Mobile also lists a Home Internet-equipped retail
location at 5135 W Alabama St., Houston, TX 77056.
Google Fiber Texas service-area information
Google Fiber's current Texas page identifies Austin and San Antonio
service areas. Houston is therefore not presented here as a confirmed
Google Fiber residential market.
Research limitation:
ZIP-level research cannot substitute for a live provider qualification
check. Provider footprints, network construction, building agreements,
plan availability and network capacity can change. This page therefore
avoids presenting a single ZIP-wide availability percentage as a
guarantee for any household.
