Is there a reverse fax number directory that will give me that information? Although I’m aware of several online reverse telephone directories, I am not aware of any that are dedicated to searching fax numbers. There’s no reason you shouldn’t try using a regular reverse phone directory to look up the number.

The good news is, when it comes to both phone numbers and fax numbers, a directory is a directory is a directory. Which is to say, you can look up a fax number the same way you look up a phone number, so any of the free online reverse phone directory services would have what you need, if the number is listed.

Ouch! I don’t know of a reliable way to find out who owns a fax number. I would start by Googling that number on the chance that it’s listed on some company’s web site. Next, I’d try using the services listed in this answer about reverse phone number lookups. With those services, you can enter a phone number and may find out who it ...

If Google doesn’t uncover the number’s owner, you could try a reverse phone directory such as AnyWho. Most include fax numbers as well as land lines. Make sure that the fax cover sheet clearly states to whom the fax was supposed to be directed and includes language noting that the content of the document is confidential, for the intended ...

The easiest course of action would be to call the voice or customer service numbers listed on the fax and politely explain that you want to be removed from the faxing list immediately.

The best way to address this issue is to use a reverse phone number directory. There are a lot of services available through the internet, both free and paid, and many of them include fax numbers as well. I would recommend starting with directories that are known for being extensive, reliable and free. You could also try simply Googling the number.

Try Googling the fax number with dashes, i. e., “123-456-7890” to see if that pulls up a company. If it doesn’t, you may have to pay for access to a reverse-lookup fax number database. Most such databases will let you enter a number and tell you if they have a record on it, for free.

Google the number or try a reverse phone directory. Those are probably your most reliable ways. If you want to take a chance and don’t mind bothering strangers, try phoning one number less (e.g. if you accidentally faxed 212-555-1234, call -1233) in case someone has their voice line adjacent to their fax line.

The only difference is the phone number that you’ll dial. When sending a fax from one U.S. city to another, you dial a 1, then the area code, then the seven-digit phone number. When sending a fax from the U.S. to another country, you usually dial 011, then the country code, then a city code (which is like an area code), then the phone number.

You dial the phone number, insert the paper, and most of the time, a copy of your document will appear on the right person’s desk — almost immediately and without fuss. Sure, you can send a document via e-mail, but there’s the chance that the recipient doesn’t have the same application (Microsoft Word or PagerMaker or whatever) to view ...
