You’re standing in the middle of a trail in Yosemite, or maybe you’re trying to pin down the exact entrance of a warehouse that doesn't have a mailbox. Address searches fail you. They're too broad. They're imprecise. This is where Google Maps search by lat long saves your life—or at least saves you twenty minutes of driving in circles.
Most people think you just toss some numbers into a search bar and magic happens. Kinda. But if you’ve ever ended up in the middle of the Atlantic Ocean because you forgot a minus sign, you know it’s a bit more finicky than that. Geographic coordinates are the literal DNA of the planet. Getting them right requires a mix of precision and knowing which format Google actually likes.
Why the Format Actually Matters
Standard addresses are messy. They rely on human naming conventions, zip codes, and municipal boundaries that change. Coordinates? They’re absolute. But the problem is that there isn't just one way to write them. You've probably seen those long strings of numbers with degrees, minutes, and seconds symbols. Or maybe just two long decimals.
Google is surprisingly flexible, but it has limits.
If you’re using Decimal Degrees (DD), it looks like 41.40338, 2.17403. This is the gold standard for digital mapping. It’s clean. It’s easy to copy-paste. However, if you're pulling data from an old maritime chart or a specialized hiking GPS, you might be looking at Degrees, Minutes, and Seconds (DMS), like 41° 24' 12.2" N 2° 10' 26.5" E.
Here is the thing: if you mix these up, or if you put the longitude before the latitude, Google Maps will get very confused. It’s always Latitude first. Always. Think of it alphabetically: Lat before Long.
The Step-by-Step Reality of Finding a Spot
Let’s say you have the numbers. You open the app or the browser. You paste them in.
- Open Google Maps on your computer or phone.
- Type the coordinates into that search box at the top.
- Hit enter or tap the magnifying glass.
Simple, right? But what if you’re trying to do the reverse? What if you’re looking at a spot on the screen and you need those numbers to send to a friend?
On a desktop, it’s a right-click. A little menu pops up, and the coordinates are right there at the top. Click them, and they’re copied to your clipboard. On mobile, it's a "long press." You hold your finger down on the map until a red pin drops. Scroll down in the location details, and you’ll find the Google Maps search by lat long data you need.
The Common Mistakes That Send You to Antarctica
Honestly, the most frequent error is the "minus sign" mishap. Latitude represents North/South of the equator. Longitude is East/West of the Prime Meridian.
In the Western Hemisphere (like the United States), your longitude is almost always going to be a negative number. If you forget that little dash, you aren't in New York anymore; you’re somewhere in Kyrgyzstan.
Decimal points are another one. Google Maps needs periods, not commas, for the decimals. If you’re in a country where commas are the standard decimal separator, you have to consciously switch to dots. Otherwise, the search engine treats the comma as a break between the two coordinates, and the whole thing breaks.
- Degrees, Minutes, Seconds (DMS):
41°24'12.2"N 2°10'26.5"E - Degrees and Decimal Minutes (DMM):
41 24.2028, 2 10.4418 - Decimal Degrees (DD):
41.40338, 2.17403
Most pros stick to Decimal Degrees. It’s just less work. Fewer symbols to mess up.
Real-World Utility: Beyond Just Finding a House
Why do we even care about this? Why not just use Plus Codes or "What3Words"?
Because Google Maps search by lat long is the universal language of GIS (Geographic Information Systems). If you're a drone pilot, you need these. If you're a geologist, these are your bread and butter. Even for casual users, think about "off-grid" locations. National parks often don't have street names. If you’re meeting someone at a specific trailhead or a rocky outcrop, an address is useless.

I once worked with a delivery team trying to find a specific construction gate on a massive site. The "official" address took them to the corporate office three miles away. By sending the exact lat/long of the gate, we cut their delay time to zero.
Understanding the Limits of Accuracy
Is it perfectly precise? Usually, yes, down to about a few centimeters if you use enough decimal places. Google Maps generally displays about five or six decimal places.
At six decimal places, you’re looking at a precision of about 0.11 meters. That’s roughly the size of a large grapefruit. For 99% of human activities, that’s more than enough. If you’re trying to guide a precision-guided tool or something scientific, you might need more, but for finding a parked car or a specific tree, six decimal places is the sweet spot.
Also, keep in mind that maps aren't always updated. The coordinate will be right, but the satellite imagery might show a vacant lot where a building now stands. Trust the numbers over the visual if you know the numbers are fresh.

Pro Tips for Power Users
If you do this a lot, stop typing the symbols. You don't actually need the little degree (°) symbol for Google to understand you. You can just type 41 24 12.2 N 2 10 26.5 E and it will figure it out.
Another weird quirk: Plus Codes. Google has been pushing these lately. They’re like shortened versions of coordinates (e.g., 8FVC9G8F+6X). They’re cool, and they work in the search bar too, but they aren't as universal as raw lat/long. If you're communicating across different platforms—say, from Google Maps to a Garmin device—stick to the raw numbers.
Summary of Actionable Steps
Stop guessing and start pinning. If you want to master this, here is your immediate checklist for the next time you're out:
- Check your hemisphere. If you are in the US, your second number (longitude) must be negative. If you are in the UK or Europe, it depends on which side of the Prime Meridian you're on.
- Use Decimal Degrees. It's the most "copy-paste" friendly format for mobile and web.
- Format correctly. Use periods for decimals and a single comma to separate the two strings of numbers.
- Right-click to extract. Don't hunt for info; right-click any spot on the desktop map to instantly see the coordinates.
- Verify the result. Before you drive two hours, zoom out on the map after searching to make sure the pin dropped in the right country. It sounds silly until you've made the mistake.
Coordinates are the most honest way to describe where you are on this spinning rock. Use them.
