Yes, most employers accept a signed offer letter sent by fax, and a faxed signature is treated as valid in many hiring situations. Send the full signed document, keep the confirmation page, and ask the employer to confirm receipt in writing, since the job is not locked in until they say so.
In most hiring situations, yes. Employers routinely accept signed offer letters by fax, and a faxed signature is generally treated as evidence that you signed, just as a scanned signature sent by email is. Employment law in both the US and Canada focuses on whether both sides agreed to the terms, not on whether the ink touched the original page. That said, an employer's own process can be stricter than the law. Some companies, especially larger ones with a formal onboarding system, want the signed offer uploaded to a portal or signed with an electronic signature tool, and a fax to a general office number may sit unread while your start date approaches.
Before you fax, read the offer letter's own instructions. Many offer letters state exactly how to return them: a portal link, an email address, or a fax number. If the letter names a method, use that method. If it says nothing, or if it lists fax as an option, faxing is a reasonable choice. If you are unsure, a short email to the recruiter asking whether fax is acceptable takes minutes and removes all doubt.
Send the complete signed offer, every page, not just the signature page. Offer letters often include terms on earlier pages: salary, start date, work location, probation or at-will language, and benefits eligibility. The employer needs the whole document to file it, and you want the filed copy to match the copy you read. Initial any pages the letter asks you to initial, sign and date the signature page, and check that your signature is dark enough to survive a fax. A light pencil signature or a faint pen can vanish in transmission, leaving a blank signature line on the employer's copy.
Add a cover sheet with your full name, the position title, the date, your phone number and email, and the number of pages. The cover sheet does two jobs: it tells the employer's mailroom or HR desk where the pages belong, and it gives them a way to reach you if a page arrives unreadable. Without it, a multi-page fax can land in a shared tray with no clear owner.
| Step | Why it matters |
|---|---|
| Read the return instructions in the offer | The letter may require a portal or email instead |
| Sign and date every required page | An unsigned page can stall onboarding |
| Send all pages, in order | HR files the whole document, not just the signature |
| Add a cover sheet with your contact details | Routes the fax to the right desk and person |
| Call or email to confirm receipt | Confirms the offer is filed, not just sent |
Some employers ask for the original signed letter as well, and there are a few situations where that is more likely. Government roles, roles with security clearance, and positions with a formal employment contract rather than a simple offer letter are the usual cases. A contract with negotiated clauses, or a role where the signed document itself is the legal agreement, may need a wet-ink original on file. The offer letter will usually say so, with words like "please return the signed original" or an instruction to bring the original on your first day.
If the employer wants the original, fax first for speed and then mail the original, or bring it on day one if they say that is acceptable. Tell the recruiter you have done both, so nobody wonders why two copies arrived. Keep a copy of everything you sent, plus the fax confirmation page, until you have a written confirmation that your acceptance is recorded and your start date is set.
The most common failure is not legal at all: it is logistical. A fax to a general HR number can sit in a tray over a weekend, or land on the wrong floor. A second failure is a missing page, which the employer may not notice until onboarding stalls. A third is timing: if the offer sets a deadline for acceptance, a fax sent on the deadline day but confirmed the next day can create an argument about whether you accepted in time. Send early in the day, confirm receipt the same day, and get that confirmation in writing, even if it is just a reply email saying "received, thank you."
One more caution: do not fax an offer acceptance to a number you have not verified. Offer letters sometimes circulate with outdated HR fax numbers, and a signed document with your salary details should not travel to a stranger's machine. Verify the number with the recruiter or on the company's own careers page before you send.
LetterAgent faxing is available in testing for US and Canadian numbers, with a per-fax quote you approve before sending. It sends the document you provide; it cannot confirm that an employer has filed your acceptance, so ask the employer for that confirmation yourself.
