How to Upload a Hash File into your account

1. Complete the following steps to upload a hash file into your Switchboard account:

   1. Settings > Organization Settings > Hashed Files

   2. Upload your .csv of hashed phone numbers. NOTE: The .csv file should only contain one hashed phone number per row - files with multiple columns will be rejected.

      

   3. Once your file has been processed, it will show as COMPLETED .
