What city is 85128 in?
Every home sold in ZIP code 85128 over the past year carried a Coolidge address. Note that a mailing address is not the same as a city limit — check the parcel itself for jurisdiction, taxes and services.

Coolidge Unified District serves most of ZIP code 85128 — it is the district listed on 100% of homes sold over the past year. The high school most often listed is Coolidge High School.

Manufactured and mobile homes are a distinct market here, and ZIP code 85128 has a sizeable one: 4% of sales, at a median of $197,625 across 14 sales. Site-built homes are counted separately, at $285,000. The two are not directly comparable — many manufactured homes sit on leased land, so the price covers the home and not the ground under it.
Is 85128 served by APS or SRP?
Both, depending where. About 36% of ZIP code 85128 falls inside APS's certificated territory and the rest does not — the boundary runs through this ZIP rather than around it. Service territory follows historical boundaries rather than ZIP codes, so check the address.
Is any part of 85128 in a flood zone?
No. No Special Flood Hazard Area — the 1%-annual-chance zones that trigger a lender's flood insurance requirement — is mapped anywhere inside ZIP code 85128, which puts it among the minority of Phoenix-area ZIPs with none at all. FEMA revises these maps, so a purchase should still confirm the current determination for the address.
