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?
Automated document collection cuts turnaround to an average of 3 days.
Direct HMRC integration verifies UK employment history in minutes, not days.
The candidate-facing portal carries your agency's own branding.
Custom check packages and reference questions save and reuse across clients.
Integrates with Workday, Greenhouse, Pinpoint and other ATS or HRIS platforms.
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.
- 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 from one provider relationship.
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
What are Zinc's pros and cons?
Pros
- Integrates with major ATS and HRIS systems, so screening fits into your existing workflow without manual handoffs.
- Handles compliance across 190+ countries automatically, removing the need to maintain separate tools or regional processes.
- Automates the entire screening process from candidate submission to report delivery, cutting administrative overhead for hiring and operations teams.
- Candidates receive real-time status updates and keep proof of right-to-work on their profile, improving their experience of the hiring process.
Cons
- Pricing is not publicly listed and requires contacting sales, making it difficult to budget before speaking with the vendor.
- Limited transparency on which specific checks are included in standard packages versus custom pricing tiers.
- Requires candidate cooperation to complete the verification form; if a candidate delays submission, the entire screening timeline extends.
