Why should I validate a Worker Checks police check certificate?

A printed PDF certificate is just a copy that can be edited or forged with basic software. By validating it using the QR code or 6-character validation code, you view the authentic result rendered live from Worker Checks' proprietary private blockchain. This is the only way to confirm the certificate is genuine and has not been tampered with.

What is the Worker Checks private blockchain?

Worker Checks uses a proprietary private blockchain built entirely in-house to store police check results. Unlike a traditional database where records can be altered or deleted, data written to the blockchain is immutable and cryptographically sealed. It is not related to cryptocurrency or Bitcoin. No third-party platforms have access to the blockchain or your data.

How do I validate a Worker Checks police check?

There are two methods: (1) Scan the QR code printed on the top-left of the certificate using your phone camera, or (2) Visit app.workerchecks.com/Validate and enter the 6-character validation code found at the top of the certificate. Both methods will display the authentic, blockchain-verified result.

Is it free to validate a Worker Checks certificate?

Yes, validation is completely free and does not require an account. You simply enter the validation code and your contact details. A one-time verification link is sent to your email. The applicant will be notified that their record has been viewed.

What is the difference between the PDF certificate and the validated on-screen result?

The PDF certificate is a convenient printed copy, but like any PDF, it can be edited or forged. The validated on-screen result is rendered live from Worker Checks' proprietary private blockchain. It is immutable, cryptographically sealed, provably authentic, and cannot be altered or deleted. Always validate to ensure you are viewing the genuine result.

Will the applicant know I validated their police check?

Yes. When you validate a certificate, the applicant is notified that their record has been viewed. This provides a transparent audit trail and ensures full accountability for both parties.

A PDF can be edited. A blockchain record cannot.

Any PDF — from any provider — can be modified with basic software. If someone provides you with a Worker Checks certificate, always validate it using the QR code or validation code on the document. The on-screen result you see after validation is the only version guaranteed to be authentic — it's read directly from our immutable private blockchain.
