Standard Fax Broadcast List Formats

Creating your standard fax broadcast list

You have the flexibility to submit your fax list in multiple formats, including comma-separated value (CSV), Microsoft Excel® .XLS, or .XLSX files.

If you choose to use Microsoft Excel® .XLS or .XLSX files, please keep in mind the following important points:

  • 1

    To avoid any processing issues, make sure you have only one sheet in your spreadsheet. Openfax does not support multiple Excel worksheets for processing.

  • 2

    Refrain from using hidden, filtered, or calculated fields in your Microsoft Excel® file. Our Openfax systems do not consider these fields, which could lead to the unintended faxing of your entire list.

  • 3

    For a seamless experience, we strongly advise saving your Microsoft Excel® files in comma-separated value (CSV) format. Before submitting the file for your fax broadcast, it’s a good idea to review the file output to ensure that everything appears as intended.

Setting up your fax list

When sending faxes within North America, the format for the fax number field is quite flexible. When creating a list with fax numbers, remember these guidelines:

  • 1

    Label the column for fax numbers as “Fax”, “Faxnumber”, or “Fax Number.”

  • 2

    If you have both North American and international numbers in the same list, add a “1” before all North American numbers to indicate the country code. If your list only contains North Americana numbers prefixing the fax number with a 1 is optional.

  • 3

    The format for North American numbers can be flexible, including non-numeric characters like hyphens, parentheses, dashes, spaces, periods, or others. International numbers should follow their respective country codes and formats.
