To put things in perspective, I’ll now find Zip code by latitude and longitude for restaurants in Oklahoma 🥘 Follow me closely, and make sure you don’t get lost.

Let’s go!

Case 1: Converting latitude longitude to Zip code using an existing coordinates list

For now, I’ll assume you already have a list of coordinates that you want to convert to Zip codes.

To convert these coordinates to Zip code, You’ll need a combination of 2 automation bots: the Coordinates to Address Finder and the Address to Zip Finder.

Step 1 - Converting lat long to addresses

For the first step, you’ll need to find the addresses that are associated with the longitude and latitude data you have. Here, you’ll need the Coordinates to Address Finder, which does exactly what its name depicts: it extracts the addresses that are associated with coordinates.

To use the Coordinates to Address Finder, you must first open a free account on Botster:

Your credit card details are not required, but make sure you confirm your email address to receive your files. Now you’re ready to get Zip code from longitude and latitude.

Launch the Coordinates to Address Finder by clicking on “Start bot”:

On the next page, name your job and specify a folder if needed.

I named mine “Oklahoma Zip code from latitude and longitude”, which is very descriptive:

Next, copy and paste your latitudes and longitudes into the “Coordinates” box.

Each lat-long pair must go on a new line, and it may be separated by a comma and a space, a space only, or a comma only:

Set up notifications and how you’d like to receive your file:

Finally, click on “Start this bot” on the right to launch the Coordinates to Address Finder into action!

There! You’ve completed the first step in how to get Zip code from latitude and longitude!

Once it’s completed, you’ll receive the Zip code-coordinates Excel file in your email. Here’s what the results look like:

Tips

Before we proceed to the final step of getting Zip code from lat-long, here are 3 tips that can help you get the most out of your results:

Send marketing materials to the addresses you've extracted through direct mail marketing.
Use the addresses extracted above for further extraction using the Address to Zip Finder as described below.
If you would like to combine email marketing and cold calling with direct mail marketing, my guide on how to build a business contacts database is a must-read for you.

Step 2 - Converting addresses to Zip codes

Now, for the final step in this step-by-step guide of getting Zip code by lat long, we will use the Address to Zip Finder to extract the Zip codes associated with each address.

Launch the Address to Zip Finder’s start page and name your job.
In the textbox titled “Country”, enter the originating country of the addresses:

Next, copy and paste the data in the “Address” column from the previous Excel file and paste them into the “Addresses” textbox:

Now click on “Start this bot” and launch this Zip code by coordinates finder tool into action!

Results

This automation tool will extract all the Zip codes attached to the addresses you’ve submitted in less than a minute and send a final Excel file to your email address:

And there goes the final step in how to get Zip code by latitude and longitude. Now combine the two resulting tables to put your coordinates, Zip codes and addresses together:

The steps outlined above seem all cozy and rosy (and truly, they are cozy and rosy), especially if you’re a property manager.

But what if you are a marketer who doesn't have a list of coordinates yet? Or worse, you don’t even have a list of the customers to begin with.

Well, fear no more, for that’s what I’ll be covering next. I’ll be showing how to find businesses that you can send direct mails to, and how to find Zip code from latitude and longitude of those businesses.

Tips

But before we get to that, here are 3 tips you can leverage to make better use of your Zip code latitude-longitude csv:

Use the extracted Zip codes for finer targeting in your digital ads campaigns.
Send direct mail to addresses you’ve generated, introducing yourself and your services with the aim of building relationships.

Case 2: Finding Zip code from lat long using a newly created coordinates list

If you don’t have an existing coordinates list, here’s how to find the coordinates of your prospective customers.

Step 1: Making a bulk coordinates list

Meet the Google Maps by Radius Finder, an automation software that can find and extract the details of any company listed on Google. The Google Maps by Radius Finder is not a lat-long Zip code converter, it will only find businesses.

Launch the Google Maps by Radius Finder’s start page and name your job.
Next, enter the keywords related to your target.

Since I’m searching for restaurants, I’ll use the keywords related to restaurants:

Next, select the radius range you want the tool to search:

Finally, set your desired starting point for the search and start the bot!

Note: Make sure the name of the location remains in the textbox.

Now wait a few moments for the tool to gather your results.

Results

The resulting file will look something like this:

In reality, the result you’re seeing above is not everything that the Google Maps by Radius Finder extracted. It extracts a lot more, including the restaurants’ phone numbers and even website URLs.

Tips

Here are some tips on how to use the data you’ve extracted:

Probably the first thing you should do with the data you just extracted is to remove duplicates. This is especially important if you use multiple keywords that are related to the same business.

Select the name column and remove duplicates. Make sure the removal extends to other columns.

Add the extracted company phone numbers to your SMS campaign database.
Use the extracted company websites to scrape email addresses as described in how to create a B2B lead generation database.

Step 2: Extracting Zip code by latitude and longitude

Now, you’ve fetched the coordinates for your own customers.

Would you like to put your knowledge of how to find Zip code based on latitude and longitude to the test?

Use the steps I described in Case One above to turn coordinates into addresses and then addresses into Zip codes 😉

Zip code - latitude longitude: Excel not applicable?

When talking about how to get Zip code from coordinates, you may think of Excel first. However, Excel may not be the best option for you.

If you would like to find Zip code by coordinates in Excel without the help of the automation tools I mentioned above, your process will look something like this:

1. Find a Lat-Long Database:

You’ll first get a pre-existing Lat-Long database that also includes matching Zip codes for each entry. There are various sources available online, and you can find free or paid databases.

2. Import and prepare the Database:

Open Excel and import the coordinates database into a new Excel file. Typically, these databases are available in CSV format.
The database should have columns for Zip code, latitude, longitude, and probably other information such as the address.
In a new column, say column C, create a concatenated key that combines the longitude and latitude into a single cell. In cell D2, enter the formula:

=A2 & " " & B2

Drag down from the corner of cell C2 to activate the formula for other rows.

3. Prepare Your Data:

In the main worksheet where you have the coordinates you wish to replace with Zip codes:

In one column, list the coordinates that you want corresponding Zip codes for.
In an adjacent column, use Excel's VLOOKUP or INDEX-MATCH functions to look up the corresponding latitude and longitude from the Zip code database.

Here's how you might use the VLOOKUP function (assuming your own coordinates are in column A starting from row 2, and the latitude-longitude database is in another sheet named "CoordDatabase"):

In the Zip code column (let's say starting in cell B2), enter:

=VLOOKUP(A2, CoordDatabase!A:D, 3, FALSE)

The formula above will look up the coordinates in column A of your main sheet, search for it in the "CoordDatabase" sheet, and retrieve the corresponding Zip code from column C.

After setting up the formulas for the first row, use Excel's autofill feature to populate the formulas for the entire column of Zip codes. You should now have Zip codes for each latitude and longitude values in the adjacent columns.

There goes the step-by-step process of how to get Zip code from latitude longitude.

👎 Several problems are inherent in this method. Some of them include:

Pre-existing coordinates databases might not cover every possible longitude and latitude, especially if they are not regularly updated.
The data in the coordinates database may be inaccurate, and may in fact have been made up in the first place. Also, the coordinates may not match the Zip codes attached to them in the database if the file is outdated.
Depending on the source of the longitude and latitude database, there might be legal or licensing considerations when using and distributing this data.

On the other hand, the automation tools that can help you get Zip code from lat-long that I showed you above are connected to Google’s API. So it has unhindered access to updated data 💪

Besides, it is faster, more efficient, and will automatically package your data into an Excel file.

Cost of finding Zip code by lat long in bulk

The price of using the automation tools I mentioned above to convert lat long to Zip code is so low you could even say they're free.

Converting longitudes and latitudes to addresses with the help of the Coordinates to Address Finder costs just $0.07 for 10 addresses and a meager $0.70 for 100 coordinates.
Extracting Zip codes from addresses using the Address to Zip Finder costs just $0.08 for 10 addresses and $0.80 for 100 addresses.
Finding and extracting business information with the help of the Google Maps by Radius Finder costs just $0.09 per keyword and is not affected by the number of businesses it finds within the specified radius.
