Update Monday 8th August 2016: The pan-US chart has been added to this product.
We have just released our first commercial product on the Mileage-Charts.com website.
This product consists of mileage charts of driving distance and travel time between US zipcodes. This is supplied as two archives. The first contains an Excel workbook for each US State, listing distances and travel times between all zip codes for that State. The second lists driving distances and travel times for all zipcodes across the US, in a text (CSV) file. Due to the large size of this latter file, all routes are listed as source,destination pairs; one per row. Duplicates are listed in a separate file, and distances and times are only give in one direction (from lowest zipcode to highest zipcode).
Prices start at US$50 for an individual license, and this includes both archives. The charts are available for immediate download, or a ‘backup DVD’ can be mailed for an additional US$15.
