Certificate Security Features

CRB certificates contain a number of security features that can be used to verify whether a CRB check has been counterfeited or altered in any way. If you are unsure whether a CRB certificate is genuine, or if you think that it may have been altered, please contact the CRB.

The security features are:

• a 'crown seal' watermark repeated down the right hand side of the CRB certificate, which is visible both on the surface and when holding the CRB certificate up to a light source;
• a heat sensitive diamond-shaped security panel to the left of the CRB certificate title, which will change colour when warmed, for example when held between the thumb and forefinger;
• a background design incorporating the word CRB checking which appears in a wave-like pattern across both sides of the document. The colour of this pattern is uniform across the front of the CRB certifcate but alternates between pink and green on the reverse side;
• fluorescent inks and fibres that are visible under UV light. These take the form of coloured flecks scattered across the CRB certificate and additional 'crown seals'. Various parts of both the text and background design will also be highlighted by UV light;
• ink and paper that will change colour in the presence of water or solvent based liquid.

This information can be made available in a number of other language and formats, please contact the CRB on 0870 90 90 811
