New file type restrictions

January 4, 2023
Bandwidth Dashboard

In order to improve security and reliability, we are limiting the types of file uploads we support for both port-in documents and import TN documents. We are also adding validation to ensure that the content-type header, the file type extension, and the MIME-type are consistent with each other.

Effective March 2, 2023, Bandwidth will allow only the following types of files to be uploaded:

  • CSV (“text/csv”)
  • DOC (“application/msword”)
  • DOCX (“application/vnd.openxmlformats-officedocument.wordprocessingml.document”)
  • JPG/JPEG (“image/jpeg”)
  • PDF (“application/pdf”)
  • PNG (“image/png”)
  • TXT (“text/plain”)
  • TIFF (“image/tiff”)
  • XLS (“application/”)
  • XLSX (“application/vnd.openxmlformats-officedocument.spreadsheetml.sheet”)

If you have any questions regarding this upcoming change, reach out to your Bandwidth Support Team!
