Missing Phone Number

When uploading a data file with a phone number column that contains no actual phone numbers, the system will not generate an error message.

Instead, upon data loading, COS will indicate that the number of duplicate or invalid records equals the total number of lines in the file.

Please note that if your file lacks a designated phone number column, COS will automatically select the first available column containing numerical data (such as age or ID number) during the upload data preview stage.

To ensure proper data processing, we recommend verifying column assignments before finalizing the upload.
