All 26 ZIP codes, and how few are ordinary delivery routes
Every one of the 26 ZIP codes USPS assigns to "Lubbock, TX" as the primary place name sits inside Lubbock County, per this site's source data, which simplifies things compared with the multi-county sprawl on this site's Atlanta or Chicago lists. Lubbock has been the seat of that single county since 1891, so there's no courthouse ambiguity layered on top of the ZIP map either.
What the county-level view hides is how few of those 26 codes correspond to an ordinary delivery route. zip-codes.com's own breakdown for the city counts 16 standard codes, 7 PO Box-only codes, and 3 unique codes reserved for a single organization apiece, meaning fewer than two-thirds of Lubbock's ZIP codes are the kind that covers more than one address.

The three unique ZIPs, and the campus that isn't one of them
Lubbock's three unique ZIP codes each belong to a single organization, per zip-codes.com's own classification: 79430 is Texas Tech University Health Sciences Center's School of Medicine, at 3601 4th Street, which opened as Texas Tech University School of Medicine in 1969; 79457 is the City of Lubbock's own mailing address, PO Box 2000, confirmed on the Texas Municipal League's directory of city officials; and 79491 is tagged "United Marketing of Texas" in that same dataset.
What that list leaves out is easy to assume wrong. 79409, the ZIP anchoring Texas Tech University's main campus itself (the classrooms, the football stadium, student housing), doesn't carry the unique designation at all. zip-codes.com classifies it as Standard, the same category as an ordinary residential block, even though its own population count for that ZIP is zero. The unique label in this site's data isn't a reward for institutional size; it marks a ZIP built around a single recipient rather than a delivery route with more than one address on it, and a university's main campus, however large its footprint, still reads as one Standard-type delivery area.
79401 and the tornado that changed how damage gets measured
79401 covers downtown Lubbock, including the 20-story Metro Tower at 1220 Broadway, known when it opened in 1955 as the Great Plains Life Building, then the tallest building in the city. On the night of May 11, 1970, an F5 tornado tore through that same stretch of downtown as part of an 8.5-mile path that killed 26 people, according to Wikipedia's sourced account of the storm; NOAA's Storm Prediction Center lists it as the 24th F5 or EF5 tornado recorded in the United States since 1950.
The Great Plains Life Building itself took heavy damage and sat vacant for years before reopening as residential lofts in 1975. Wikipedia's entry on the building notes it's the second-tallest building on record to survive a direct F5 hit, behind only the ALICO Building in Waco. The broader damage survey Ted Fujita conducted across the city afterward, matching wind-speed estimates to specific patterns of structural failure, fed into the Fujita Scale he introduced the following year, the same F-scale this site uses elsewhere to describe tornado intensity.
806: the one Texas area code that's never needed relief
Area code 806 has covered Lubbock, Amarillo, and the rest of the Texas Panhandle since 1957, when it was flash-cut out of 915 and picked up a small piece of 817 along the way. Texas had six area codes in service by 1983: 214, 512, 713, 817, 915, and 806. Every one of the other five has since been split, overlaid, or both; 214 alone has spawned four additional codes since 1953. 806 hasn't. Checked against this site's own records for all six of those original codes, the pattern holds: five separate histories of splits and overlays after 1983, and one, 806, with nothing recorded past its 1957 creation.
NANPA's own numbering data backs that up going forward, not just backward. The agency's 2025 annual report lists 806 with no overlay complex at all, still N/A in its own overlay-tracking table, and just 156 of a forecast 312 number blocks assigned, roughly half the code's practical capacity. NANPA's latest projection puts exhaustion at the first quarter of 2032, five quarters later than the agency's prior forecast, meaning the pressure on 806 eased rather than mounted between the two reports.
