If your fax keeps failing with No Answer or No Fax Detected to the same number, while faxes to other numbers go through, the problem is usually the recipient's number, not your account.
Test the number with a phone call
- Call the recipient's fax number from any phone.
- Listen to what answers:
- High-pitched beeps or a screeching sound - this is a fax tone. The line can receive faxes. Try sending again, and if it keeps failing, contact our support team.
- A person, voicemail or a phone menu - this is a voice line, not a fax line. Ask the recipient for their correct fax number.
- Ringing with no answer, silence, or a "not in service" message - the fax machine is off, not set to auto-answer, or the number is no longer in use. Contact the recipient to confirm the number.
Can a recipient refuse faxes sent online?
No. Faxes sent from Fax.Plus reach the recipient over the phone network, just like faxes sent from a fax machine. The recipient's fax machine can't tell the difference, so it can't reject a fax because it was sent online. If a fax to one number keeps failing while others succeed, check the number itself using the test above.
Sending to a government office
Government agencies often use different fax numbers for different programs or offices, and these numbers can change. Always check the current fax number on the official form or the agency's website, or confirm it with the agency directly. Many agencies also accept documents online or by mail.
