Why fax still matters in the US
Many US banks, insurers, clinics, courts and government offices still accept documents only by fax. If you run a business from outside the US, a fax machine and a landline are rarely practical. Online fax gives you a US fax number that turns faxes into PDF files.
How online fax works
- Receiving: someone faxes your number, the carrier converts it to a PDF and it appears in your dashboard. You also get an email notice.
- Sending: you upload a PDF and type the destination fax number. The carrier dials the other machine and transmits the pages.
- Status: each fax shows whether it was delivered or failed, with the page count.
Send your first fax
Add the Fax add-on to a number you do not need for calls: while fax is on, that number works as a fax line. Then open Faxes, choose Send fax, upload a PDF of up to 10 MB and 30 pages, and enter the fax number with its area code.
Costs and good practice
- Receiving is included for normal business use; sending is charged per page from your wallet. Failed sends are not charged.
- Use a clear, black-and-white PDF: fine text and photos lose detail over fax.
- Keep a copy of what you sent. Received faxes are stored as PDF files you can download at any time.
- Do not fax content that the law restricts, or confidential data beyond what you are allowed to send.
