To minimise the risk of fraudulent duplication of Certificates and Parchments they are printed on security paper that includes watermarks and a hologram. Certificates and Parchments are individually numbered. NEBOSH maintains records of all Certificate and Parchments issued and reissued. Once a replacement has been issued, the original Certificate will no longer be valid.
If a lost or stolen original is later presented to NEBOSH for authentication it will be identified as invalid.
For more information see our Policy regarding candidate certificates including corrections and reissues.
