Morrisville, NC uses two ZIP codes — 27560 and 27519 — and neither one maps cleanly onto the town. 27560 is the Morrisville-specific code; 27519 is shared with Cary and covers only part of Morrisville’s west side. A Morrisville mailing address does not by itself confirm the county, the property tax rate, or the school assignment that applies to a given house — those are three separate maps that happen to overlap here.
What ZIP codes cover Morrisville, NC?
Two ZIP codes serve Morrisville addresses: 27560, which the United States Postal Service assigns primarily to Morrisville, and 27519, a larger code shared with Cary that reaches into Morrisville’s western neighborhoods. Cary’s own ZIP codes overlap 27519 as well, so a 27519 address alone does not tell you which town’s ordinances or tax bill apply.
| ZIP code | Areas covered | County | Notes |
|---|---|---|---|
| 27560 | Most of Morrisville, including the town center and neighborhoods east of NC-54 | Wake County, with a portion crossing into Durham County | The primary Morrisville-designated ZIP (USPS) |
| 27519 | Western Morrisville and a large share of west Cary; USPS lists Cary as the default city name | Wake County only | Shared with Cary; not exclusive to Morrisville |
What county is Morrisville, NC in?
Morrisville sits mainly in Wake County, but a portion of the town extends into Durham County. The town line, not the ZIP code line, is what actually determines county jurisdiction — a house with a Morrisville mailing address can sit in either county depending on exactly where the parcel falls. Morrisville’s town profile covers the broader picture; for a specific parcel, the county line is confirmed by the Wake County GIS or Durham County GIS parcel lookup, not by the ZIP code.
Does a Morrisville ZIP code mean the property is inside Morrisville’s town limits?
Not necessarily. ZIP code boundaries are drawn by the Postal Service for mail routing and often extend beyond a town’s legal limits, or stop short of them. Some addresses with a 27560 or 27519 ZIP code sit in unincorporated Wake County rather than inside Morrisville’s corporate limits, which affects which government sets the property tax rate and which ordinances apply.
Does a Morrisville ZIP code determine school assignment?
No. Morrisville is served by the Wake County Public School System, which assigns students by attendance zone, not by ZIP code. Two houses sharing the same 27560 ZIP code can be assigned to different elementary, middle, or high schools depending on the attendance boundary a specific address falls in. Buyers who need a specific school should check the assignment directly rather than infer it from the mailing ZIP — see how Wake County school assignment works.
Why don’t ZIP codes, town limits, and school zones line up?
Each boundary was drawn by a different authority for a different purpose. USPS draws ZIP codes around mail carrier routes and redraws them as delivery volume changes. The town of Morrisville draws its corporate limits through annexation, one parcel or subdivision at a time. Wake County Public Schools draws attendance zones around building capacity and redraws them as enrollment shifts. None of the three agencies coordinates its lines with the others, which is why the same ZIP code can span two counties, two tax jurisdictions, and several school assignments at once.
Which Morrisville ZIP codes cross into Durham County?
ZIP code 27560 is the one that crosses into Durham County; 27519 does not. Durham County’s own GIS address-point layer lists thousands of address points inside Durham County carrying ZIP code 27560, with “Morrisville” as the recorded city, and lists no address points anywhere in the county carrying ZIP code 27519 (Durham County GIS, Address Point layer, queried September 2026). A parcel’s county matters directly to a buyer: it determines which county sets the tax rate, which Register of Deeds records the closing documents, and which county assessor’s office to contact for a revaluation question — see how Wake and Durham County property taxes compare.
How many people live in each Morrisville ZIP code?
A ZIP code’s population count describes the full extent of the postal boundary, not Morrisville’s town limits — and because 27519 is mostly Cary by land area, any population figure published for that ZIP code says little about Morrisville specifically. A town-level population figure for Morrisville itself is better sourced from the US Census Bureau than backed into from ZIP code data.
What should a buyer actually check instead of the ZIP code?
Three separate lookups answer three separate questions: the county GIS parcel search confirms county and tax jurisdiction; the Town of Morrisville’s boundary map confirms whether a parcel is inside the town limits; and the Wake County Public Schools assignment tool confirms the specific schools. A closing attorney or the Wake County Register of Deeds can confirm which jurisdiction actually recorded the deed if there is any doubt.
Who does relying on the ZIP code alone not suit?
Anyone comparing two specific houses on tax rate, school, or which town government to call about a permit should not treat “Morrisville, NC” on a listing as a complete answer. It is a mailing convenience, not a legal or administrative boundary. Buyers weighing Morrisville against Cary in particular should confirm county and school assignment parcel by parcel rather than by ZIP code.
