For Addresses (Geocoding)
- Be sure that there are no spaces before or after the end of your address, city, zip code, or other letter and number strings. ArcMap tries to read these as part of the name, etc..
- Make sure that addresses are split into different fields for street address, city, and postal code.
- Street addresses should have no periods in them, even for abbreviated terms like Ave, W, E, or St.
- Use common abbreviations like Ave, W or St. You may also spell the words out, ie: Lane or Circle.
- Double check the spelling for streets and cities. Be sure that your spelling and abbreviations match exactly the official street name. Is it "Mount Carmel Ave" or "Mt Carmel Ave?" Database entries are matched exactly, so your entries for upload should match as exactly as possible.
If there are mistakes in your data for geocoding, there are ways to rectify them. See the tutorial information on
