Fax number format from mobile fax

[LC133]

I’m trying to send a fax from the HP printer app from my phone. I put all the information in and it keeps telling me invalid fax number format. I’ve put the number in correct but yet it still won’t let me use it.

Hi @LC133,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

That sounds frustrating! Let's try to troubleshoot the issue together. Here are a few things you can check.

• Country Code: Ensure that you're including the correct country code before the fax number. For example, if you're in the United States, the country code is "+1".
• Area Code: Make sure you're including the correct area code if necessary. Some fax numbers require an area code, while others don't.
• Formatting: Double-check that you're entering the fax number in the correct format. It typically looks like this: +[Country Code][Area Code][Fax Number]. For example, a fax number in the United States might look like +1-XXX-XXX-XXXX.
• Special Characters: Avoid using any special characters or spaces in the fax number. Stick to numbers only.
• Leading Zeros: Remove any leading zeros from the fax number.
• Test Another Number: If possible, try sending a fax to a different number to see if the issue persists. This can help determine if the problem is specific to the fax number you're trying to use.

I hope this helps.

Take care and have a good day.
