How to verify an offer or employment letter

An employment or offer letter is the easiest document in any application stack to fabricate, because it has no system of record behind it. A pay stub comes from a payroll platform and a statement comes from a bank, but a letter is just a letter: anyone with a word processor and a logo can produce one in five minutes. Verifying one means accepting that the document itself can prove very little, then squeezing what evidence it does carry, and confirming the rest at the source.

What the file can still tell you

Even a simple letter leaves records. A letter genuinely produced by an HR department typically comes from office software or an HR platform, created in one pass, with no edit layers from consumer PDF editors. A letter assembled from a template or altered from a real one often shows a converter or editor as producer, a creation date minutes before it was sent to you, or author metadata naming someone other than the letterhead's company. If the company digitally signs its HR documents, growing practice at larger employers, a valid signature settles content integrity outright, and a missing or broken one where signing is standard is a real finding.

The mismatch pattern is the one to remember: a letter claiming to be from a Fortune 500 HR system, carrying the fingerprints of a free online PDF tool, is not what it claims to be, whatever the salary line says.

The two checks that settle it

First, the callback. Find the company's main number independently, through its website or directory listing, and ask for HR or the named manager. Never call the number printed on the letter, which is exactly where a fabricated letter routes its accomplice. Second, where stakes are high, ask for source confirmation: an email from the company's verified domain confirming the role, or employment verification through the employer's official channel or service. Honest candidates and employers handle both without friction.

FAQ

The letter is signed in ink and scanned. Is that better?

No. An ink signature proves nothing about who held the pen, and scanning erases the file's own records. Scanned letters shift all the weight to the callback.

The email came from the company's domain. Done?

A matching sender domain is meaningful evidence, much stronger than the letter itself. Check that the domain is exactly right, lookalike domains with one letter changed are a standard trick, and remember that an attachment can still be edited after a real employee sent the original.

What about offer letters from small companies?

Small companies have thinner paper trails, so the callback carries everything. A company too small to verify is a finding in itself for a lending or leasing decision.
