Frequently Asked Questions
#1. How long will it take for me to receive the file ? A download link will be sent to you automatically as soon as the purchase is completed, the entire process usually takes less than a minute.
#2. What is the difference between a 1-Month and 1-Year subscription ? The subscription is the period during which you can download the updates of your file for free. Once the period has expired, you will have to make a new purchase in order to be able to download new updates. The use of the data is not limited in time.
#3. I don‘t have a Paypal account, can I still buy your files ? Yes. No Paypal account is required to make a payment through Paypal, a debit or credit card is enough.
#4. I haven’t received any confirmation email for my purchase what must I do ? The confirmation is sent to the email address registered with your Paypal account (or the one you provided during the checkout process). Keep in mind to also check your 'spam' folder, our message may have been filtered by mistake. If you still cannot find any message please contact us.
#5. My payment has been refused. What can I do ? Online payments are verified by PayPal, we are unable to process any order following a card declined by PayPal. Please contact PayPal directly in case of any issue with payment.
If your payment is refused :
- If the amount exceeds 1000 Eur, you MUST be registered at PayPal and have a verified account, otherwise the payment will be automatically refused.
- Most PayPal accounts have a transaction limit as well as a monthly payment limit which depends on the country and on the account status. Please check whether this limit has not been exceeded. Should that be the case, please contact PayPal in order to know how to increase your limit or remove the limitation.
- If you do not have a credit card or if your card is not accepted, please note that you can usually open a PayPal account without having a credit card. You just need to transfer money from your bank account (the conditions may vary from a country to another).
- If it is not possible for you to make payment via PayPal, please contact us in order to let us propose you an alternative. We reserve the right to refuse your order if we do not have enough elements guaranteeing the payment.
#6. I’ve lost my download link, can you resend it ? If you have lost the confirmation email or download link we sent you, please contact us within the 10 days after the purchase, and provide your name, email address and date of purchase.
#7. My download link is not working anymore, why ? The download link sent after your purchase remains active for 30 days. After this period, it is no longer possible to access the file unless you place a new order.
#8. I get an error message during the download, what can I do ? First please try again later, the server may be temporarily overloaded or have encountered a technical problem. You may also try with another browser and/or a different internet connection. If you still cannot download the file, please contact us.
#9. I get invalid characters during the import procedure, why ? Our files are encoded in Unicode UTF-8, the international multilingual format. You may have to manually set your software import configuration to this format if it is not recognized automatically.
#10. How often are files updated ? Our files are updated every month. However if no update is deemed necessary, the current version will remain unchanged.
#11. How accurate are the geographical coordinates ? The geographical position (Latitude, Longitude) is precise to about one hundred meters and corresponds to the center of the locality (generally the historical center, otherwise the geographical center). In some countries, the ZIP code refers to a block or a street, in which case the coordinates point to that specific location.
#12. How to calculate the distance between two cities ? The formula used to calculate the distance between two geographical points is called orthodromy, it is defined as follows : | Distance(A,B) = 6371 * ACos( Cos(LatA) * Cos(LatB) * Cos(LngB - LngA) + Sin(LatA) * Sin(LatB) ) | The resulting number is the distance in kilometers between point A and point B. If you wish to return a result in miles (or any other unit), you must substitute the value 6371, which stands for the approximate radius of the Earth in km, by its equivalent in miles (or any other unit), that is 3959 miles. Latitude and longitude values must be input in radians : radians = degrees * PI/180. Excel template is available here.
#13. How to find the closest locations to a set point ? Having a database of localities with their latitudes (Lat) and longitudes (Lng), enables you to locate the closest cities to a set point (or within a radius of X) with the following query: | SELECT Name, 6371 * ACos( Cos(RADIANS(Lat)) * Cos(RADIANS(UserLat)) * Cos(RADIANS(UserLng) - RADIANS(Lng)) + Sin(RADIANS(Lat)) * Sin(RADIANS(UserLat)) ) AS Distance FROM Cities ORDER BY Distance | The UserLat and UserLng values should be replaced by the coordinates of the starting point. To limit the search to a given radius, you can add a WHERE clause to the distance; you can also specify a LIMIT clause to display only the n cities closest to your starting point.
#14. Can I get a physical copy of the data ? No. Our databases are only available for download. Besides being faster to access, this method also allows us to provide you with the lowest prices, which would no longer be possible with the shipping of any actual physical items.
#15. I’m not satisfied by my purchase, can I obtain a refund ? You may extensively review the material available on our website before completing any purchase to ensure that our files match your requirements. Therefore we generally do not offer any refund. However if for some reason you feel you are entitled to one, please feel free to send us a request through our contact form stating your case.
#16. Can I redistribute your databases within my software or my website ? You may use and distribute the content of our files in your applications (software or websites) as long as the goal of those applications isn’t solely to exploit our data. For more details please read our Terms and Conditions of Sale.
#17. I have found a ZIP code that is not in your file Only ZIP codes pertaining to a geographical location (city, town, district, ...) are available in our databases. Some countries have 'administrative' ZIP codes used to designate mail sorting offices, public offices, corporations, etc... Those ZIP codes are not included into our databases aswell as PO Boxes.
#18. I found missing or inaccurate information, what should I do ? We strive to keep our databases as accurate as possible. However if you were to come across any inaccurate information please feel free to let us know through our contact form. Should it be confirmed we would send you an updated version of the file.
#19. I would like to obtain data for a country you do not currently offer We are always adding new countries to our databases. Please feel free to contact us about your request, it will allow us to better direct our efforts in the future.
If you have any other questions, please feel free to contact us.
