Latitude and longitude finder: what should it give you?

A good latitude and longitude finder names the place it found, works backwards from a point, finds your position and takes a list. Seven checks, tested.

Every latitude and longitude finder gives a pair of numbers, but the pair alone does not say which same-named town answered, or whether it is right. So what should a finder give you besides the numbers? The facts that name the place, a way back from a point to a place, your own position, and room for a list.

Those decide whether you can trust a pair before pasting it into a form, and whether fifty places cost one search or fifty. The fastast latitude and longitude finder does all four for towns and cities; it does not take street addresses.

What should I check before using a coordinate finder?

Seven things: the format of the pair, the facts that name the place, the reverse lookup, your own position, distance and bearing, lists, and street addresses.

What to check	Why it matters	The fastast finder, tested September 2026
Format of the pair	Software, spreadsheets and map search boxes read decimal degrees, latitude first	Decimal degrees, latitude first, up to five decimals, a copy button on each row; the top match also in DMS, DDM, UTM, MGRS, Plus Code and geohash
Which place answered	A name shared by several towns returns one pair per town	Region code, country, time zone, population and, when known, elevation on each row; up to twenty rows, most populated first
Reverse lookup	A bare pair from a photo or a spreadsheet means little until it is a place	“A point instead of a name” lists the five nearest places, each with its distance
Your own position	“My lat long” is a question for your device, not a name to type	“Use my position” fills Latitude and Longitude from the browser, to four decimals
Distance and bearing	Two places raise the question of how far, and which way	“Distance to” adds the great-circle distance in km and miles, and the initial bearing
Lists	Fifty places typed one by one are fifty chances to copy the wrong row	“Several places at once” takes up to 100 names, one row per name found, in the order given
Street addresses	A door number needs a street-level geocoder	Towns and cities only: “10 Downing Street, London” returns “No place found for this search”

Can a finder turn a latitude and longitude back into a place?

A good one can, and it is the quickest way to learn where a pair from a photo, a GPS track or a spreadsheet points. In the fastast finder, open “A point instead of a name”, leave the place name empty and fill in Latitude and Longitude.

The answer lists the five nearest places, each with its distance in kilometres, its country and its time zone. Both fields take decimal degrees. A place added in “Distance to” is then measured from your point, not from the nearest town.

Can it give me my current latitude and longitude?

Yes, if your browser can locate you and you allow it. The “Use my position” button, under “A point instead of a name”, fills Latitude and Longitude and empties the place name; Search then lists the five places nearest to you.

The position is rounded to four decimals, about 11 metres at the equator according to Wikipedia’s table of decimal degrees. The button only appears in browsers that can report a position.

Can it take a whole list of places?

Yes: paste up to 100 place names, one per line, under “Several places at once”, and each comes back as one row, in the order you typed them. Lines that match nothing, such as a street address, are listed apart under “Not found:”.

Each row keeps only the best match, the most populated place whose name starts with the line: “Springfield” comes back as Springfield, Missouri. Read the region code on each row before you use its pair.

Questions

What are the places listed “at the same latitude”?

The five most populated places within a quarter of a degree of the top match’s latitude, anywhere in the world. For Paris, they are Volgograd, Stuttgart, Volzhsky, Marne La Vallee and Karlsruhe.

What does the initial bearing mean?

It is the direction you set off in, in degrees clockwise from north, shown with the nearest of sixteen compass points, such as NE. The bearing changes along a long route, so the finder gives the one at departure.

Where do the coordinates come from?

From GeoNames, a public gazetteer published under a Creative Commons licence and credited under every answer. It records each place as one point in decimal degrees on WGS 84, with its region code, population and time zone.
