Common errors and troubleshooting
Reasons why you may be getting an error message when trying to upload your file for a diagnostic or cleansing report:
- Is the file one of our accepted file types? Note: we do not currently support the .xlsx file format.
- Do the columns in your file match one of our 4 approved address formats? Read our File Format Guidelines for details and examples. Also note that all the columns must be accounted for. For example:
- If you don’t have data for “First Name”, insert a column and leave it blank.
- If your list contains residential addresses only, insert a “Business Name” column and leave it blank.
- Do you have additional data in your file that isn’t part of our standard fields? Note: all the columns must be accounted for and no additional columns of information are allowed (this includes blank columns to the right of the final data column).
- Is your Record ID more than 15 characters long? Record IDs cannot be longer than 15 characters (including alphanumeric characters, symbols and spaces).
- If you are trying to submit a comma delimited .csv file, make sure there are no commas in your address or name fields.
