Where pathological and biological specimens are to be sent by parcel, applications must be made to Royal Mail Parcelforce to obtain prior approval to do so. The veterinary surgeon or analytical laboratory organizing the despatch of the samples will need to contact the Customer Care Unit Manager of the local Parcelforce office, quoting the postal code of the despatch unit. For further information, contact the Parcelforce National Enquiry Centre (Freephone 0800 224466) or the local Customer Care Unit.
