Authenticity of section 49 notices
4.24 It is essential that any person who is given a notice is able to confirm its authenticity should they need to do so. In practice the giving of a notice will be a stage in the progress of an investigation or operation and the person given the notice will usually have been involved earlier in that process, either as a consequence of their arrest or having been identified as being in possession of a key to the relevant information.
4.25 In addition to the statutory requirements all written notices must include a unique reference number, must identify the public authority and must provide the address of an office and a published contact telephone number using which the recipient of a notice may check its authenticity.
-  See paragraph 4.12
4.26 Public authorities must provide a means for authenticating any notice they give at whatever time the notice is given. In addition, the person giving the notice should, when doing so, carry sufficient identification to confirm their office, rank or position and, if requested to do so, should produce that identification to the person being given the notice.
