How to verify previous employment, step by step

Verifying previous employment means confirming with a candidate’s past employers that the jobs on the resume actually happened: right company, right dates, right title. Done systematically it takes a defined sequence rather than luck. This guide covers the manual process end to end — and where each step can be shortened with verified records.

Step 1: get consent and set expectations

Before contacting anyone, obtain the candidate’s written consent to verify their employment history — a legal requirement in most jurisdictions and basic fairness everywhere. Tell them which employers you will contact and ask up front for anything that will smooth the process: HR contact details, the name the candidate worked under if it has changed, and any employer that no longer exists (so you can agree substitute evidence early instead of discovering the problem mid-process).

Step 2: contact the right channel at each employer

• Prefer official channels — the company’s HR department reached through its published contacts, not a mobile number the candidate supplied. Numbers provided by candidates verify that someone answers them, nothing more.
• Put the request in writing where possible — company letterhead or a company-domain email, stating the candidate’s consent, the facts to confirm (dates, title), and a reply route. Written answers are auditable; phone notes are not.
• Expect policy limits — many employers confirm only dates and title as blanket policy. That is still a verification: dates and title are exactly what resumes most often inflate.
• Log every attempt — date, channel, person reached, answer given. If verification later matters in a dispute, the log is your evidence of diligence.

Step 3: evaluate what comes back

Compare answers against the resume with tolerance for honest noise: a month of date drift or a slightly different title wording is normal memory and HR-system variance; six months of drift or a materially different seniority is a conversation with the candidate before it is a conclusion. Where an employer cannot answer — closed, merged, unresponsive — ask the candidate for substitute evidence: employment contracts, pay slips, tax or social-insurance records naming the employer. Weigh substitutes as supporting evidence, not proof; they confirm a relationship existed but are also the easiest documents to forge.

Step 4: know when to outsource — and when none of this is needed

For high-stakes roles, regulated industries, or histories spanning several countries, a professional verification service with local presence earns its per-candidate fee — scope it to the employers that matter rather than the whole resume. And increasingly there is a faster path altogether: candidates whose employers issue verified records need no phone chain at all. On EmployDB, a recruiter requests access and, with the candidate’s consent, reads employment history issued by verified employers at the time it happened — positions, dates, promotions, certificates with evidence attached. The manual process above remains necessary for history outside the network; inside it, verification is a permission grant that takes minutes.
