Allen, TX, sits about 20 miles north of downtown Dallas – a well-established northern suburb inside the Dallas-Fort Worth metroplex. If you’re shopping for a home here, you’ll want to get oriented quickly: understanding how the city is divided by postal code makes your search a lot more precise, whether you’re filtering MLS listings or figuring out which school district a specific street falls into.
The local market runs at a steady clip. The median sale price is around $504,700, and homes are spending roughly 34 days on the market. Knowing your way around the postal boundaries means you can track inventory in specific parts of the city rather than casting a wide net and hoping for the best.
The Primary Zip Codes for Allen, TX
Allen works with just two zip codes: 75002 and 75013. That’s it – two codes for the entire city, splitting it into eastern and western sections.
The 75002 zip code covers the primary and eastern portions of the city. The 75013 covers the western side, including downtown. When you’re searching listings, running both numbers gives you the full picture of what’s available inside the city limits.
Neighborhoods Within Allen’s Postal Boundaries
The two postal codes divide Allen’s residential developments into distinct search areas, and it’s worth knowing which neighborhoods fall where before you start touring.
The 75013 zip code covers the western and downtown districts. If you’re looking there, you’ll come across neighborhoods like Twin Creeks, Watters Crossing, and Starcreek. Over on the eastern side, 75002 holds communities like Cottonwood Creek, Suncreek, and The Village at Allen. Other neighborhoods spread across the city include North Allen, Central Allen, and Upper Preston Lake.
County Lines and Metro Connections
Allen falls entirely within Collin County – no straddling county lines the way some other Dallas-Fort Worth suburbs do. That keeps things relatively straightforward from a tax and jurisdiction standpoint.
Sitting about 20 miles north of downtown Dallas, Allen functions as a significant residential hub within the Dallas-Fort Worth-Arlington metropolitan statistical area. If you’re relocating from out of state, make a point of verifying Collin County property tax rates early. That number has a real effect on your monthly carrying costs, and it’s better to know it before you fall in love with a listing.
Local Landmarks and Postal Mapping
A zip code map is more useful when you can anchor it to something on the ground, and Allen has a few landmarks worth knowing.
The most recognizable is the Old Stone Dam. Built in 1874 as a steam locomotive watering station for the Houston and Texas Central Railroad, the dam is accessible today through Allen Station Park. It sits within the city’s postal boundaries and gives residents a concrete geographic reference point when trying to get their bearings between the 75002 and 75013 areas.
Finding Your Full Nine-Digit Postal Code
The five-digit codes – 75002 and 75013 – handle most everyday purposes, but the United States Postal Service also uses a ZIP+4 system that drills down to specific streets, apartment buildings, or even individual sides of a block.
You’ll need that complete nine-digit code when setting up utility services or forwarding mail. The easiest way to get it is to plug the exact property address into the official USPS lookup tool. It generates the full routing number immediately.
Real Estate Market Activity Across Allen
Buyer demand has been consistent across both zip codes. As of mid-2026, the median sale price for a home in Allen is roughly $504,725, and properties are selling for approximately 98.5% of their list price.
There’s some room to breathe on inventory – around 410 available homes representing about 3.7 months of supply. With 338 homes sold recently and a median of 34 days on market, you don’t need to panic, but you do need to be ready. When you find the right house, a hesitant offer is rarely a winning one.
Frequently Asked Questions
What are the main real estate differences between the 75002 and 75013 zip codes in Allen?
The 75002 zip code covers the eastern and primary sections of Allen, while 75013 covers the western and downtown areas. Neighborhoods like Twin Creeks and Watters Crossing are on the western side, whereas communities like Suncreek are on the eastern side.
Which zip code in Allen, TX typically commands the highest home prices and resale value?
Both zip codes feed into the city’s overall median sale price of approximately $504,725. What actually drives individual home prices is the specific neighborhood – Starcreek versus Upper Preston Lake, for example – not the postal code itself.
Do homes in all Allen zip codes automatically zone to Allen ISD?
School boundaries don’t follow zip code lines. Before you assume anything about school zoning, check the specific property address directly with the local school district rather than relying on whether it’s 75002 or 75013.
Do property tax rates or MUD fees vary depending on your Allen zip code?
Property taxes are determined by Collin County and the specific municipal utility districts a home sits in – not by the postal code. Review the tax records for each individual listing before you make an offer.
Which Allen zip code is best for finding new construction homes versus older, established neighborhoods?
Both 75002 and 75013 contain a mix of housing ages. The western 75013 area includes established downtown properties, while developments like Cottonwood Creek and The Village at Allen offer different construction styles across the city.
Are there any parts of Allen that share a zip code with neighboring cities like McKinney or Plano?
The 75002 and 75013 zip codes are dedicated to Allen, TX. That said, because Allen is a northern suburb inside the Dallas-Fort Worth metroplex, city limits and postal boundaries can create some confusion near the edges of Collin County – especially if you’re searching by zip code alone.
