Follow these address guidelines for best performance and results:
- Your input address record file can contain addresses from multiple countries. Make sure you include the ISO Alpha-2 or Alpha-3 country code, or the common country name for each input address. For a listing of the supported countries and ISO country codes, see Supported Countries.
- Ensure that your input addresses are as complete and accurate as possible. If there are errors in your input addresses, MapMarker may still be able to geocode those addresses, but the results may be less accurate.
- Format your input addresses consistently. You can get more accurate and faster results if your addresses are consistently formatted and conform to postal address conventions.
- It is recommended not to use whitespaces or special characters in the input address file name or in the column header names.
