How to Verify a Job Offer Is Legitimate Before You Resign

Job offer fraud is more common than most candidates expect, and it tends to target people who are already under pressure to leave a bad situation. The mechanics vary: fake employer domains, misrepresented compensation, roles that don't exist once you've resigned. A few hours of verification work before you sign protects against all of it.

Start With the Employer's Identity

Before anything else, confirm the company is real and the person extending the offer actually works there. This sounds obvious. It trips people up anyway.

1. Look up the company on your state's Secretary of State business registry. A legitimate employer will have a registered entity, usually with a formation date that predates the offer.
2. Check the domain of every email you've received. Free email domains (gmail, yahoo, outlook) from someone claiming to represent a mid-size or large employer are a red flag. Look at WHOIS records for the domain's registration date.
3. Cross-reference the hiring manager on LinkedIn. Confirm their employer matches the company, their tenure is plausible, and their profile has real history.
4. Call the company's main switchboard number from their public website. Ask to be connected to the hiring manager or HR contact by name. If the number doesn't exist or no one recognizes the name, stop.

JobClarity's CheckRecruiter feature automates a significant portion of this. It runs domain age checks, MX and SPF DNS record analysis, SAM.gov registry lookups for federal contractors, and community flag aggregation. You get a signal score with a breakdown of what drove it, which is faster than doing each lookup manually.

Read the Offer Letter Like a Contract

An offer letter is a legal document. Read it as one. Most candidates skim for the salary line and sign. That's where problems start.

• Confirm the legal entity name on the offer matches the company you interviewed with. Subsidiaries and holding companies are legitimate, but you should know which entity is employing you.
• Check the start date, title, compensation structure, and reporting line. All four should match what was discussed verbally.
• Look for clawback clauses on signing bonuses and relocation assistance. Understand the repayment window before you accept.
• Note what's missing. A legitimate offer letter includes benefits summary, at-will language (in most US states), and a clear compensation breakdown. Vague or missing sections warrant a follow-up question before signing.
• If equity is part of the package, the offer should reference a separate equity agreement. If it doesn't, ask for it in writing before your start date.

Verify the Compensation Against Market Data

Salary figures in offer letters can be misrepresented in both directions. Some fraudulent offers use inflated numbers to create urgency. Some legitimate employers lowball candidates who haven't checked the market. Either way, you want current, role-specific data before you negotiate or accept.

JobClarity's Market Intelligence pulls salary distributions by role and location using current data, not year-old BLS aggregates. If the offer is at the 20th percentile for the role in your metro, you should know that before you sign. If it's at the 80th, that's useful context too.

A salary that seems unusually high for a role you barely interviewed for is a signal worth investigating, not celebrating.

Trace the Original Job Posting

Pull up the original posting you applied to and compare it against the offer letter. The job title, responsibilities, and reporting structure should be consistent. Material discrepancies between the posted role and the offer are worth raising explicitly before you sign.

Also check how long the posting has been live and whether it has been reposted repeatedly. A role that has been cycling through job boards for months with no hires may indicate a pipeline-building exercise rather than an active opening. JobClarity's Verify feature scores postings on signals like repost cadence, description quality, and employer posting history. If the posting that brought you in scored Low Signal or Minimum Signal, that context matters when you're evaluating the offer.

Confirm Before You Resign

The single most costly mistake in a fraudulent offer scenario is resigning before the offer is fully confirmed in writing. Verbal offers are not offers. An email saying "we'd like to move forward" is not an offer letter. Wait for the signed document, complete your verification steps, and only then give notice.

If an employer pressures you to resign or start before paperwork is complete, that pressure itself is a signal. Legitimate employers understand that candidates have professional obligations to manage. A tight but reasonable timeline is normal. Urgency designed to skip verification steps is worth scrutinizing.

• Get the offer letter in writing, signed by an authorized company representative.
• Complete your employer identity and recruiter checks before giving notice.
• Verify compensation against current market data for your role and location.
• Compare the offer terms against the original job posting.
• Ask for any verbal commitments (title, remote policy, equity, start date) to be reflected in writing.
