A small business can get a free fax number through eFax, FaxBetter, Voxox or FaxBetter, as Bob Rankin's technical support website explains. All of these services allow a small business to receive inbound faxes electronically and without the use of a physical fax machine.
Free inbound fax services have limitations. K7, for instance, requires a user to receive at least one call or fax within 30 days in order for the free account to stay active. FaxBetter users must get a fax every seven days to keep their free toll-free fax numbers, and the service restricts incoming pages to 20 per month. EFax provides a local number but not a toll-free one, and it limits inbound pages to 10 a month. Voxox appears to not restrict the number of inbound pages, but the process of downloading the software and creating an account can be confusing, according to Bob Rankin.
A small business can also use any phone number to receive and send faxes without the need for a fax machine. Computers can come with fax modems and software to do the job, as Bob Rankin explains. PC owners can use Windows Fax and Scan to turn their computers into fax machines, notes Microsoft.
