What is Zinc?
Zinc is a background and reference checking platform focused on simple, mobile-first global checks, commonly used by UK-based and European hiring teams and embedded into HR platforms via direct integration. Your team initiates checks directly from a candidate's profile; Effi Flo's role is wiring that initiation into your ATS workflow as a trigger-based step so checks fire automatically at the offer stage rather than requiring a recruiter to remember to start them.
What are Zinc's key features?
Average 3-day turnaround on background checks: Automated document collection and reference follow-ups compress what used to be a slow manual process into a few days - keeping a placement from stalling while a check is pending.
Direct HMRC integration for instant employment verification: Employment history checks complete in minutes rather than days for UK hiring - removing one of the most common bottlenecks in pre-placement verification for agencies operating in the UK market.
A branded experience candidates don't see as third-party: The candidate-facing portal can carry your agency's branding, so a check feels like part of your process rather than a handoff to an unfamiliar vendor mid-placement.
Reusable check packages for repeat client needs: Custom packages and reference questions can be saved and reused - useful when your agency runs the same verification requirements across multiple candidates for the same client.
Connects to the ATS and HRIS your team already runs: Effi Flo integrates Zinc with Workday, Greenhouse, Pinpoint, or your platform of choice so verification results land directly in the candidate record your recruiters use.
How do recruiting teams use Zinc?
- A UK-focused agency uses Zinc's reusable global right-to-work verification to avoid re-running the same compliance check every time a candidate changes employer, letting candidates hold a portable verified identity that speeds up onboarding for future placements.
- An in-house TA team prioritizing candidate experience uses Zinc's branded, self-serve verification portal to keep the background check step feeling like part of the employer's own hiring process rather than a handoff to a third-party vendor.
- A boutique agency conducting right-to-work checks across EU and UK markets uses Zinc's multi-country coverage and IDVT-certified digital identity verification to stay compliant across jurisdictions without managing a separate provider relationship per region.
Who is Zinc best for?
- High-volume hiring teams in retail, hospitality, and logistics that want a branded, candidate-facing verification experience covering both background checks and reference checks
- Organizations that want verification and reference collection running through the same platform rather than managing separate vendors for each
- Startups and fast-moving teams that value real-time status updates and a modern, mobile-friendly candidate process over deep enterprise customization
