What is my ZIP code?
See what ZIP code you’re in right now, lit up on the map with its county, local time and the numbers behind it.

Your ZIP in three ways
No forms, no sign-up. Pick whichever feels right.
- 1
Pin your exact spot
Your browser asks once whether this site may use your location. Allow it, and your ZIP lights up with a blue outline, plus how far you are from its edge. - 2
Search a ZIP, city or address
Type 3 digits and pick from the list, type a city, or paste a street address for an exact answer without sharing your location. - 3
Tap anywhere on the map
Checking a new apartment, a job site or a friend’s place? Tap it. Zoom in and every ZIP code shows its outline and number.
What ZIP code am I in right now?
Your mailing ZIP and the ZIP you’re standing in are usually the same, but not always. When you pin your spot, the map answers the second question: the ZIP area that contains the point where you are, outlined in blue.
- How far the edge is. The card measures the distance from your point to the nearest edge of the ZIP, and the direction. Under about 0.15 miles, it warns you that a few doors over could be a different ZIP.
- Somewhere else, too. Tap any spot on the map, a new apartment or a job site, and the answer updates for that point without reloading.
- An address with its own ZIP. Type a street address and, if its mailing ZIP differs from the area it sits in (common for PO Box, campus and big-building ZIPs), the page tells you which one goes on mail.

What your five digits mean
Every ZIP is a little address for the mail system. Type one and watch it break down.
- 9
First digit: one of 10 national areas
9 is Pacific: AK, CA, HI, OR, WA, GU. Numbers start at 0 in the Northeast and climb to 9 on the Pacific.
- 902
First three: the mail processing region
All ZIPs that share their first three digits are sorted at the same regional facility.
- 10
Last two: the local delivery area
The post office or delivery zone within that region. ZIP+4 adds a block, a building or a PO Box group on top.
These are the colors on the zoomed-out map. See them all on the ZIP code map.
Why your ZIP can look wrong
ZIP codes were made for delivering mail, not for drawing maps. A ZIP is really a set of delivery routes run from a post office, and that causes a few surprises.
- Your internet connection isn’t your location. IP-based guesses point to wherever your provider routes traffic, which can be a city or even a state away.
- Some ZIPs have no area at all. PO Box ZIPs and single-building ZIPs, like 10118 for the Empire State Building, are points. About 7,800 of the 41,637 ZIPs we track have no outline.
- Edges are fuzzy. Two houses across a street can have different ZIPs. When you pin your spot, the card tells you how far the edge is.
The outlines here are the Census Bureau’s ZIP Code Tabulation Areas. They match USPS ZIPs for almost every home, but not all. If your lease, a maps app and the post office disagree, the post office wins for mail: check the USPS ZIP Code lookup, which also gives your ZIP+4.
ZIPs don’t stop at county lines
We compared every ZIP code area with county boundaries from the 2020 Census. 30% of ZIP areas (10,186 of 33,791) reach into more than one county, and 2,546 touch three or more. 137 even cross a state line.
ZIP 75080 in Richardson, Texas, is 71% in Dallas County and 29% in Collin County, so the ZIP alone can’t tell you which county a Richardson home is in. Pin your spot for the county at your exact point, or use county by ZIP code to see every county a ZIP touches.

Questions people actually ask
What is my ZIP code right now?
Tap “Pin my exact spot” and allow location access. Your ZIP code area lights up on the map with your city, county and local time. Before you tap, the page shows a guess from your internet connection, marked approximate. If you’d rather not share your location, type your street address.
Why does a gas pump ask for my ZIP code?
The pump checks the billing ZIP of your card, the ZIP of the address your bank has on file, to cut down on card fraud. It has nothing to do with where you are standing. Enter the ZIP from your card statement.
Is this the same ZIP code USPS uses?
Usually. The outlines are Census ZIP Code Tabulation Areas, which approximate where USPS delivers each ZIP. Near the edge of a ZIP, or for apartment buildings and PO Boxes, the ZIP on your mail can differ. For an address you will mail to, confirm it with the USPS ZIP Code lookup.
How do I find my ZIP+4?
The four extra digits identify a block face, a building or a group of PO Boxes, so they depend on your exact street address. Only USPS has that list: enter your address in the USPS ZIP Code lookup.
What ZIP code am I in right now?
Tap “Pin my exact spot” and allow location access. The ZIP area around you lights up with its city and county, and the card tells you how far you are from the edge of that ZIP and in which direction.
How accurate is it?
As accurate as your device’s location. Phones outdoors are usually within 5 to 20 meters; laptops on Wi-Fi can be off by a few hundred meters. If the card says you’re close to the edge, zoom in and tap your exact spot to double-check.
Can I check a place I’m not at?
Yes. Tap anywhere on the map: a new apartment, a job site, a trailhead. The ZIP at that point lights up, and its card shows how far the tapped point is from the edge.
What if I’m right on the border between two ZIP codes?
The card warns you when you’re within about 0.15 miles of an edge. Near a border, check your street address in the USPS ZIP Code lookup, which decides the ZIP for mail.
Does this site store my location?
No. Your coordinates are used once to find the boundaries you’re inside, then dropped. They aren’t saved, logged or shared. The “recently viewed” ZIPs stay in your own browser.
Why does a website show me in a different city?
Most sites guess your location from your IP address, which often points to your internet provider’s hub, sometimes in another city or state. Your phone’s GPS or Wi-Fi position is far more precise, which is why this page asks before using it.
