About Zinc

At Zinc, we believe that background checks should be instant, easy, and delightful. Yes, you read that right.

Traditional background checking providers are slow, manual, and error-prone β€” Zinc’s here to change that.

Here’s how it works:

Step one: Select your checks

With Zinc you get exactly the checks you want, and no extras you don’t. Make your own templates and re-use them, or use our pre-built packages to align with any regulatory check requirements.

Zinc offers global checks in over 190 countries, including:

Credit checks

Address verification

Reference checks

Qualification checks

For a full list, visit https://zincwork.com/checks.

Step two: Tell Zinc who you’re checking

Enter your candidate or employee’s name and email address, then click β€œRequest checks.”

The rest is easy: Candidates use our mobile-friendly platform to submit any required information, referee names, and additional documents. We’ll even chase references for you.

Here’s what Becca Covill, HR Operations Specialist at Jensten, said about Zinc references:

β€œWhen we’ve used different providers, there was a lot of manual intervention required. But with Zinc, we’ve been able to put them in, click a button, and it just runs.”

To stay in the loop, just visit your Zinc dashboard and get at-a-glance updates.

Step three: Get results, fast

With direct HMRC integrations and automated workflows, Zinc delivers results fast. Like, really fast.

β€œObviously I recommend Zinc, but an IDSP will change your life overnight. It had instant results.” β€” Zander Loftus, Recruitment Manager, Hexagon Care
