Contact the recipient by another means and ask them to check their fax machine.

Look up the recipient's current fax number. Contact them by phone or email for the correct number.

How to prevent the issue

  • Save frequently used fax numbers with the country code in a contact list.
  • Do not send important faxes right before close of business - recipient devices may already be switched off.
  • If deliveries keep failing, check whether the recipient still receives faxes.

Your fax is not being delivered? That can have various causes, most of which can be fixed quickly.

In this troubleshooting guide we show you the most common problems and their solutions.

The most common causes

In most cases, the problem is due to one of these causes:

  • Incorrect number: typing error or missing code
  • Recipient busy: the device is currently in use
  • Device switched off: recipient has not switched on the fax machine
  • Technical problem: fault at the recipient

How to check the fax number

Correct formatting of the fax number is crucial:

  • With country code: +49 30 12345678 (Germany)
  • Without special characters: no slashes, brackets or hyphens
  • Check the area code: the area code must match the city/region

With FaxMonkey the format is checked automatically before you pay.

FaxMonkey guarantee

At FaxMonkey we do everything to ensure successful delivery:

  • Automatic retries: for 'busy' we automatically try again
  • Transparent status messages: you always know what happened
  • Money-back guarantee: refund in case of non-delivery due to technical reasons (see Terms and Conditions)

Frequently asked questions

How many delivery attempts does FaxMonkey make?

FaxMonkey will automatically try several times to deliver your fax if the recipient device is not reachable on the first attempt. You will be informed about the status and, in the event of persistent failure, you can request a refund.

What does 'Line busy' mean?

This message appears when the recipient fax machine is currently receiving or sending another fax. That is normal and not a permanent problem. Wait a few minutes - our system will automatically try again.

Will I get my money back if the fax is not delivered?

In the event of non-delivery caused by a technical issue on our side, we will refund the amount. If the fax number is incorrect or the recipient device is permanently switched off or defective, the guarantee does not apply. You can find details in our Terms and Conditions.

Can I see why the fax was not delivered?

Yes. The error report provides information on the reason for the failure: 'Busy', 'No answer', 'Invalid number' or similar messages that help you troubleshoot.
