ZIP Code Radius Map — List Every ZIP Within a Radius
Search any address (or a starting ZIP), set a radius, and get every ZIP code inside the circle with its distance from the center — then download the whole list as a CSV for your CRM, mailing list or territory plan. Free, no signup.

Search an address or a 5-digit ZIP, set a radius, and every ZCTA centroid inside the circle is listed with its straight-line distance. CSV exports the full list.
Common uses
Sales territories. Draw a rep's territory around their home base, export the ZIP list, and load it straight into a CRM or mapping product as a territory definition.
Direct mail & marketing lists. Give your mailing vendor a definitive ZIP list for the area you actually serve instead of hand-picking codes from a wall map.
Service & delivery areas. Answer “do we cover ZIP 60601?” in seconds, and share a live map link with the customer so the answer is verifiable.
Franchise & site selection. Check how many ZIP codes fall inside a 20-mile ring around a candidate location before paying for a full trade-area report.
How the ZIP radius list is built (and its limits)
The tool uses the U.S. Census Bureau's ZCTA (ZIP Code Tabulation Area) centroids from the 2024 Gazetteer — a public-domain dataset of roughly 33,800 areas, one per ZIP-code-shaped region. Each match is the straight-line distance from your center point to the centroid (middle) of that ZIP area.
Two honest caveats follow from that. First, distances are straight-line: a ZIP whose centroid sits 10.0 miles away may have edges closer or farther than that. Second, ZCTAs approximate USPS ZIP codes — they usually agree, but a handful of PO-box-only or high-volume delivery ZIPs differ from census ZCTAs. For mailing-list work, vendors accept ZCTA lists as the standard approximation; for legal or regulatory definitions, confirm with USPS data directly.

Frequently asked questions
How do I find all ZIP codes within 10 miles of an address?
Type the address into the search box, set the radius to 10 miles, and the table lists every ZIP inside the circle with exact distances. Press CSV to download the full list for spreadsheets or a CRM import.
Can I search by ZIP code instead of an address?
Yes — type a 5-digit ZIP (e.g. 60601) into the same search box. The geocoder resolves it to the ZCTA centroid and the search runs from there.
Why does my ZIP list differ slightly from another tool's?
Most tools use the same census ZCTA centroids but round or measure differently, and some include/exclude PO-box ZIPs. Differences of a handful of ZIPs near the radius edge are normal — the math is a straight-line filter either way.
Does the distance use roads?
No — every distance is straight-line (great-circle) from the center to each ZIP's centroid. Roads between two points are typically 20–40% longer.
What data source is this based on?
The U.S. Census 2024 Gazetteer ZCTA file — public domain, no licensing restrictions. It contains one entry per ZIP Code Tabulation Area with its land area and internal point.
Can I export the list?
Yes — the CSV button downloads every matched ZIP with distances in miles and kilometers, ready for Excel, Google Sheets or a CRM import.
