Input Recommendations

You can optimize Geocode Address World results if you prepare and understand your input records. Follow these guidelines :

Ensure that your input addresses are as complete and accurate as possible. If there are errors in your input addresses, Geocode Address World may still be able to geocode those addresses, but there may be more than one possible match or you may get non-close matches. If you can verify and correct any incomplete or inaccurate input addresses, you can get better results.
Include postcodes in your input addresses if you have them. This is not required, but it allows Geocode Address World to perform postal geocoding. This may give you more accurate results for some addresses, depending on the country and on the completeness and accuracy of other address elements
Include the country name or official three-character or two-character country ISO code in your input addresses. This is not required, but it may help Geocode Address World distinguish between similar addresses and city names that may occur in different countries.
Format your input addresses consistently. Geocode Address World can handle input addresses in a wide variety of input formats, or can handle unformatted (single line) input. But you can get more accurate and faster results if your input addresses are consistently formatted and conform to country-specific address conventions. Even if your input address are single line (unformatted), you may get better results and performance if the address elements are ordered consistently. Use the AddressLine1 input area for unformatted addresses. See Single Line Input
