FaxTo vs FaxBurner: the free fax number that expires in 24 hours
FaxBurner exists to solve one problem well: receiving a single fax without paying for anything. It hands you a temporary fax number that works for 24 hours, plus 25 received and 5 sent pages a month on the free tier. If you need to receive one document — a signed contract, a medical record — it is the fastest free option available. It is not built for sending.

Choosing between FaxTo and FaxBurner
FaxTo suits you if…
- Your task is sending: a letter to an institution, a signed form, a scanned document.
- You send more than five pages and do not want a monthly subscription to do it.
- You need to reach a number outside the US and Canada.
- You want the document scanned, cropped, merged and cover-paged in the app you send from.
FaxBurner suits you if…
- You need to receive one fax and pay nothing — this is exactly what FaxBurner is for.
- You need a fax number in the next five minutes and only need it for a day.
- You need to sign a document and fax it back, using the built-in eSignature tool.
- You want something available right now.
A disposable number is a feature, not a limitation
The 24-hour expiry on FaxBurner's free number reads like a catch until you consider what it is for. Someone asks you to receive a fax — a bank, a clinic, a former employer. You need a number for one afternoon. Handing out a disposable one means you are not giving a permanent line to an organisation that may fax you for years. When the day is over, the number is gone.
For anything ongoing, that same expiry is the problem, and FaxBurner sells the answer: a permanent toll-free number on the $14.95 Professional plan.
Five pages a month is a receiving product
The free tier's asymmetry tells you what it is: 25 received pages against 5 sent. Five pages is one letter with an attachment. If your task is to send — and most institutional paperwork is sending — you will hit that ceiling on your first real document and be looking at a $14.95 monthly subscription.
FaxTo is the mirror image. There is no free allowance to lean on, but there is also no monthly floor: credits are bought in packs, one credit sends one page, and unused credits stay on the account indefinitely.
Where you can send
FaxBurner is built around US and Canadian numbers. FaxTo sends to more than 40 countries on every plan. If the fax number you need starts with anything other than +1, check coverage before you choose.
