Your fax shows as delivered, but the recipient says they do not have it. This page explains what “delivered” tells you and what to check.

What “delivered” means

PayPerFax marks a fax as delivered when the receiving fax machine or fax service answered the call and accepted all pages. You are charged only in this case. Delivered does not tell you:
  • Whether the pages printed, or went to an inbox if the recipient uses a fax-to-email service
  • Who picked them up
  • Whether they reached the right person or department

What your confirmation shows

The delivery email and the confirmation page give these details:
The CSID (Called Subscriber Identification) is a short text that the receiving machine sends during the call. Its owner sets it. It is often the machine’s fax number or a company name, but it can be any text, out of date, or blank.If the CSID matches the recipient’s fax number or name, that supports that the fax reached their machine. If it is blank or shows something else, that alone does not mean the fax went to the wrong place. Many machines are never set up with a CSID.

Where the fax usually is

Nobody has checked the machine yet, the fax is under other faxes, or it arrived after hours. Ask the recipient to check the machine and the tray.
In a large office, a shared machine may serve many people. The fax may be in a mailroom or with another team. A cover page that names the person or department helps next time. See Cover Pages.
A machine that is out of paper or toner can store faxes in memory, or print blank or faint pages. Ask the recipient to check the machine’s display for stored faxes or errors.
Some recipients use a fax-to-email service, which turns a fax into an email. Ask the recipient to check that inbox, its spam folder, and the service’s own log.
A fax that arrives at night or on a weekend may not be seen until the next business day in the recipient’s time zone.

What to do

1

Check your confirmation

Make sure the status is Delivered, and note the completion time and the pages sent.
2

Contact the recipient

Give them the date and time, the page count, and the CSID if it shows. Ask them to check the machine, its memory, and any fax-to-email inbox.
3

Send the PDF another way, if accepted

If the recipient accepts email or an upload, send them the PDF from your delivery email. Some legal, medical, and government processes accept only fax, so ask first.
4

Resend if needed

Use the resubmit link (valid for 72 hours) and add a cover page that names the person or department. See How to Resend a Fax.
