422 errors typically occur when the input we have received is not able to be processed successfully. For example, if an invalid or incomplete address has been provided. The error message you receive should provide some detail regarding what may be missing.
In order to determine the location of an address, Geocodio requires either a combination of city and state or a Zip Code. We are not able to process a response without this information.
For example, this address would not be able to read by our geocoder:
Whereas these addresses would be considered complete and would be much more likely to receive a response:
There are extremely rare instances where even this type of formatting might return no response. In these edge cases, try providing a complete address that includes City, State and Zip Code. In general, the more information you can provide Geocodio, the more likely will we be to be able to complete your request.
There are occasions when an address is so new that it does not yet exist in our system - or - an older address has been changed or demolished. If possible, double check to make sure that the address you are inputting is accurate and does exist. If so, proceed to the our fourth troubleshooting option.
When reverse geocoding, be certain that the following is true for any coordinates you submit:
If you are certain that the address you're submitting exists, feel free to submit an address error report through your account dashboard. We will investigate the address, do our best to identify its location, and wherever possible manually add the address to our database.
