ZipCalc measures distance between zipcodes and finds other zipcodes in a given radius. In addition, zipcode circles can be added or removed from the results. ZipCalc exports zipcode lists or SCF lists. It processes your mailing list, pulling out addresses that are not within a certain radius.
The demo version now ships with a zipcode data for the entire United States. The demo version works just like the registered version, but it will only return 20 zip codes when a search is completed. When you register, you get all of the zipcodes.
ZipCalc is a Mac, Mac OS X, or Windows application. When you purchase ZipCalc, your serial number will work for either platform.
- Export Found Zips – When you find your list of zipcodes they can be exported to a text file.
- Search Faster – ZipCalc now performs searchs in seconds!
- Now uses a database – With a database engine, we’ve made subsequent searches very fast. This also provides a base for additional features. Let us know if you have an idea!
- Find Zipcodes with in a Given Radius – Find zipcode within a given number of miles from a central zipcode. Export Zipcodes or SCF list.
- Add or Remove Zipcode Circles – After performing a zipcode search, it is easy to add or removed zipcode circles. For instance, you could search for the zipcodes within twenty miles of Orlando and then add the zipcodes that are ten miles around Tampa. Alternatively, you could remove the zipcodes around an area of town that you don’t want to include in your list..
- Split Mailing Lists Based on Zipcode List – After you find a list of zipcodes, you can split your mailing list so that you can mail local addresses only, saving postage!
- Latitude Logitude Distance Calculator – Calculate distance in miles from one set of Latitude Longitude coordinates to another set.
- Zipcode Distance Calculator – Calculate distance in miles from one zipcode to another zipcode.
I used GeoQuery years ago, but they stopped updating their zipcode database. When I found out that ZipCalc was available for HALF of the cost, I was ecstatic! I’m now using ZipCalc every monthto direct my mailings to profitable areas of town.
You can use ZipCalc for several purposes. The most useful is splitting your mailing list so that you only mail to local addresses, rather sending to a wider area than intended.
First, launch ZipCalc! We designed ZipCalc to help step you through the process. As you progress, more data and choices become available.
Next, define the base zipcode and the radius in miles and then click “Find”. Note that the first time you search for a particular zipcode/radius combination, it will take some time. If you search for the same zipcode/radius combination again, you should get an almost immediate response! When you click on a zipcode in the zipcode list, the city and state will appear for confimation.
You have three choices when finding zipcodes.
- Replace List – Completely replaces the current list.
- Add to List – Adds zipcodes to the the current list, removing duplicates. If you wanted the Dallas / Fort Worth, TX area, you might search the Dallas area first and then add the Fort Worth area.
- Remove from List – Removes zipcodes from the current list. This is useful if you want zipcodes in the suburbs, but not the downtown area. In Orlando, you might enter 32801 and 50 miles for the first search and then remove 32801 and 10 miles to avoid mailing the downtown area.
Now that you have your zipcode list ready, click “Select Mailing List” and choose your tab-delimited text file containing a mailing list. Make sure you include all the fields that you might need for the mailing, otherwise, you might need to split the list again. ZipCalc will display the first record or row of your file in the row headers AND in the first row of data. If you have column headers in your data and wish to remove it from your data, click it in the data area and choose “Remove Selected Address” from the File menu. In order to export your data into “In the Radius” and “Out of the Radius” you must choose the zipcode column header so ZipCalc knows the location of your zipcode field. You can see the “Zip” column highlighted in blue. After the zipcode column is selected, you can click on a row of data and a message will appear stating if the address is in or out of the radius.
After you choose your zipcode field, you can manipulate your data by using the options found in the File menu.
File Menu Options
- Remove Selected Zipcode – Removes the zipcode from the zipcode list. Any addresses with that zipcode will be considered outside of the radius.
- Remove All Zipcodes – Removes all of the zipcodes from the zipcode list. This is great if you’d like to start over. However, performing a “Replace List” find will achieve the same thing.
- Remove Selected Addresses – Removes an address from the mailing list.
- Remove All Addresses – Removes all addresses. Selecting a new mailing list will work just as well, if you plan to work on addtional lists.
- Export Mailing List Radius Files – Exports your mailing list into two text files containing the addresses that are “In the Radius” and “Out of the Radius”.
- Export Zipcode List – Exports the list of found zipcodes. (Not displayed in the image below)
- Import Update Zipcode Data – Give you the ability to import a tab delimited text file containing the zipcode, latitude, longitude, city, and state for a particular zipcode.
- Clear Search Cache – As you use ZipCalc it remembers the zipcode/radius results to make subsquent searches much faster. Choosing this menu item will delete the cache which will cause the search caches to rebuilt.

Questions and Answers
A: Not at this time. It uses a database of five digit zipcodes. If you were interested in custom development, we could update ZipCalc to use a web based service to use a specific address for the Search Zipcode and also convert the locations for the list of addresses based on the address rather than the zipcode.
