How verification works

Unlike LinkedIn claims, Workhistory badges are earned. Tap a badge on any role for event history — evidence files stay private.

What does Document Verified mean? expand_more

An admin reviewed an HR letter, offer, or similar document for that role. Filenames stay private.

What is Work Email Verified? expand_more

The owner proved access to an email on the employer’s domain via one-time code.

What is Employer Verified? expand_more

The company confirmed employment through the Workhistory company portal — often with a named verifier and title on the role.

What is BG Verified? expand_more

The employee submitted work emails and HR letters. AI read the original sender, dates, and role; a company-paid check (or reviewer) completed the packet. Evidence files stay private.

What are company logos on roles? expand_more

When a company domain is known, we show a logo next to the role so recruiters recognize the employer at a glance.

Can I request verification as a visitor? expand_more

Yes — open a role’s trust drawer and submit Request verify. The profile owner gets a verification nudge.

What is the SVG trust badge? expand_more

An embeddable badge at /profile/{slug}/badge.svg showing trust score, verified role count, years of experience, Featured when pinned, and Proof ID — for résumés, GitHub READMEs, and personal sites.

Can I download a resume? expand_more

If the owner published a primary resume, use Download PDF on this page. Otherwise open the trust report or Trust PDF for denser proof.

What is the Trust PDF? expand_more

A one-click PDF pack of the public trust report — score, why-signals, and employment claims — for recruiter packs without requiring a login.

What is manager impact sign-off? expand_more

Owners can request managers to confirm specific metric highlights. Confirmed impacts show on the public profile and company portal can Confirm/Deny.

How is this different from LinkedIn or a resume builder? expand_more

LinkedIn and resume tools help you claim and format experience. Workhistory badges are earned via document, work email, employer confirm, or BG — then published as a Trust Score, Proof ID, and auditable URL recruiters can filter.
