Friendswood, TX Zip Codes: 77546, County Lines, and What to Check in 2026
Friendswood, TX runs on a single zip code for virtually every street address in the city. North side or south side, the mailing zip looks the same.
Key takeaway
Friendswood's street-address zip code is 77546, while 77549 is reserved exclusively for PO boxes. The zip code will not distinguish one Friendswood home from another, so check the county side, city limits, school district, and flood zone address by address. With prices softening, buyers have room to do these checks and negotiate before making an offer.
Who this guide is for
You're looking at homes with a Friendswood address and need to know what the 77546 zip code does and doesn't tell you about a specific property before you make an offer.
What is the zip code for Friendswood, TX?
Friendswood, TX is served by two USPS ZIP Codes: 77546 for standard street addresses and 77549 for PO boxes with no street delivery. There's no single nine-digit code for the whole city. Look up the ZIP+4 for any individual property on the USPS ZIP Code Lookup tool.
77546: the main Friendswood zip code
This number covers street addresses across the entire city, on both the Galveston County and Harris County sides. Zip-level data on real estate sites blends areas with different tax and district setups into one average. The zip itself cannot tell you a home's appraisal district, county tax rate, or school district.
77549: the PO box zip code
The 77549 zip code serves PO boxes at the local post office. You may see it on a homeowner association's letterhead, a local business card, or seller mailing documents, but none of these reflect where the property sits. Search appraisal, flood, and school records by the street address with 77546.
Nearby zip codes on Friendswood listings
Homes near the city's edges sometimes carry a neighboring city's zip and mailing name. Listing descriptions may also market homes outside the city as "Friendswood" or "near Friendswood."
The city field on a listing is a USPS mailing name. It does not prove which city, county, or school district the home is in. Treat any non-77546 listing as unverified until you run the address-level checks below.
Questions to narrow your search
Work through these questions in order and skip any that don't apply:
If the listing shows anything other than 77546, read Nearby zip codes on Friendswood listings and Confirm the home is inside Friendswood city limits.
Find out whether the home sits on the Galveston County or Harris County side, since that sets the appraisal district and county tax rate. What county is Friendswood in? and Read the appraisal district record cover this.
If a specific school district matters, go straight to Look up the school district for the address.
If the home is near Clear Creek or a drainage channel, see Check the flood zone and flood history, then Friendswood housing market by the numbers for pricing room.
Three ways to start:
If you want the most negotiating room, start with listings on the market longer than 31 days. They've outlasted half of recent sales.
If you want the widest selection, start with single-family homes, which made up 216 of the 226 recent Friendswood sales.
If you want to compare two homes on true annual cost, start with the appraisal district records for both addresses.
What county is Friendswood in?
Friendswood is mostly in Galveston County, with a northern portion in Harris County. The City of Friendswood is a dual-county city: the portion north of Clear Creek lies in Harris County, and the portion south of Clear Creek lies in Galveston County.
That county line changes the appraisal district, county tax rate, and flood-control agency, even for homes with the same zip code and city name. Two houses on the same street can come with materially different tax bills, and the listing won't show it.
The Galveston County side
The Galveston Central Appraisal District keeps property records here. Its official online property search finds homes by owner, address, or property ID. That district sends your appraisal notices, and Galveston County's tax rate appears on your bill.
The Harris County side
The northern part of the city sits closest to Houston. The Harris Central Appraisal District maintains the official online real property search tool for this portion of Friendswood. Drainage and floodplain information on this side comes through Harris County's flood-control agency.
What to check by address before you make an offer
Look up the exact street address through official county and city databases rather than relying on listing remarks. Doing this before your option period ends protects your earnest money and shows the home's true holding costs. Address-level checks are just one part of the transaction; the full process outlines what to expect when buying a home in Friendswood.
Confirm the home is inside Friendswood city limits
The City of Friendswood maintains an official public GIS Interactive Map with a City Limits layer and an address lookup application. City-limits status determines your city property tax, city services, and who provides water utilities. Ask the title company to confirm whether the property is inside city limits and whether any utility or drainage district applies.
Near the edges of town, a home outside the limits may sit in a special utility or drainage district that adds its own tax line to the bill.
Look up the school district for the address
More than one district serves addresses inside Friendswood. Friendswood ISD serves the Galveston County side, and homes on the Harris County side are zoned to Clear Creek ISD.
Attendance zones for local schools can change, and listing remarks are never a guarantee. Confirm the assignment directly with the district for the exact address.
Check the flood zone and flood history
The city directs residents to FEMA's official Flood Map Service Center to check Flood Insurance Rate Maps by address. The city is affected by riverine flooding from four major creeks, including Clear Creek, which marks the county line.
Before the option period ends:
Ask the seller for an elevation certificate and any flood-claim history.
Check the seller disclosures for any past flooding the owner reports.
Get an insurance quote.
A home outside the mapped flood zone can still flood.
Read the appraisal district record
Search the address on the Galveston Central or Harris Central Appraisal District site. The record lists every taxing entity on the property and any exemptions the current owner holds.
Those exemptions don't transfer to you. A buyer who acquires a home after January 1 may receive the residence homestead exemption for the applicable portion of that tax year once they qualify. That only applies if the previous owner did not already receive the same exemption for that tax year. Because of this, the seller's current tax bill can understate yours. Budget from the taxing units and market value on the appraisal record, not from the bill on the listing sheet.

These are Friendswood city figures, not 77546-only figures. The median sale price for all homes recently sat at $403,808, a 14.1% decline year over year.
