Short answer: a fax counts as sent when you can show a record of the transmission: the date and time, the number reached, the number of pages acknowledged and a positive result. That record is produced by the machine or the online service that placed the call. Store it alongside a copy of the file you sent, since it alone distinguishes "I sent it" from "they received it".
People ask for proof for different reasons: a deadline, a contested cancellation, an insurance claim. The words "delivery receipt" cover three quite different things, and mixing them up is the commonest mistake.
Three kinds of evidence
The transmission report
The sending side generates it once the call finishes. It lists what the system saw: the number called, start time, duration, pages sent and the outcome. On a physical machine it prints on a slip. With an online service it arrives by email or appears on a status page. For day-to-day purposes it is the most useful record.
The remote acknowledgment
Fax machines talk to each other during the call. After each page, the receiving machine confirms it was received correctly. When your report says "3 pages OK", it means three confirmations came back from the other machine. That is a stronger signal than an email, where nothing guarantees the remote server stored the message.
One limit remains: this confirms the electronic reception of the pages. Whether the paper was printed, read or given to the right person stays unproven.
A read receipt
Faxing has no such thing. Nothing in the standards allows a sender to demand that the recipient acknowledge reading a page. If you need that, use another channel or follow up with a phone call and write the date in your file.
Reading a report line by line
| Field | What it tells you | Why it matters |
|---|---|---|
| Date and time | when the call took place | proves you met a deadline |
| Number called | the complete number, including country code | shows you reached the intended recipient |
| Remote identifier | text the receiving machine announces about itself | helps confirm who picked up |
| Duration | how long the call lasted | a very short call can mean a cut transmission |
| Pages | pages acknowledged | compare with the page count of your file |
| Result | OK, busy, no answer, error | the verdict |
Two fields get skipped most often. The remote identifier is sometimes left at the factory setting, but when a business has configured it, it shows that the machine answering did introduce itself under the expected name. The page count matters because "OK" on 3 pages for a 7-page file is a partial failure, not a success.
Result codes that deserve attention
- No answer. Nobody picked up. Check the number and try again at another time; the line may have been canceled.
- Busy. The line is in use. Online services usually retry several times by themselves.
- No fax tone. Something answered, but not a fax machine. The number may now be a voice line.
- Error mid-page. The connection dropped. On internet-based lines, the cause is often how fax tones are carried over IP.
When one of these appears, do not assume the recipient has your document.
What Faxturbo gives you
Every fax sent through the service has a status page and a confirmation email with a tracking link, at no charge. If you need written proof, two optional acknowledgments exist: one confirms your request was received and accepted, the other confirms the transmission. They are priced separately; see the pricing page for the current amount. They are generated as documents you can store and forward. Because the service sends faxes but does not provide a number for receiving them, the acknowledgments describe your outgoing transmissions only; our guide on receiving faxes covers the other direction.
Keeping your proof organized
- File the document and its report side by side in a single folder, and put the date in the file name.
- Note the recipient's name and the reason for sending, either in the cover sheet or in your own log. The cover-page generator helps.
- Keep it for as long as the matter lasts, plus a margin. Some professions have set retention rules; ask your advisor.
- Consider a follow-up call for high-stakes documents, and write down who you spoke to.
Frequently asked questions
Is a fax accepted as evidence?
It depends on the country, the recipient and the type of document. A report with a positive result is a solid piece of the file, but it is not a guarantee. Ask the body concerned how it treats faxes.
The report shows OK, yet the recipient claims nothing arrived. What now?
First verify the number called and the page total. Then hand over the report together with the document itself. A phone call often resolves it; the recipient's machine may simply have run out of paper.
Do I get a report for a free one-page fax?
You receive the tracking email and can watch the status page. The written acknowledgments are the paid option.
Key points
- Proof is the report: date, number, pages acknowledged, result.
- Remote acknowledgment confirms electronic reception, not reading.
- Never rely on memory: store the report with the document.
- Faxturbo provides a free status page and optional written acknowledgments.
