An adhesive tamper evident label comprises a rear adhesive surface 2 configured to adhere to a contact surface, an opposed, frangible front surface 6 and an inner layer 8. The frangible front surface is configured such that unintended tampering with or removal of the label from the contact surface causes fragmentation and/or distortion of the frangible front surface enabling at least a portion of the inner layer to be visible. The inner layer may extend across the entirety of the label or may only extend across a central portion or may be formed as spaced apart portions, e.g. stripes, dots, symbols, letters, etc. The inner layer may comprise a reflective 10, 12 layer or a holographic layer. The frangible front surface may be formed with lines of weakness, e.g. indentations, score line or perforations. The elastic modulus of the material of the front layer is preferably greater than the elastic modulus of the material the inner layer. The label is preferably a vehicle number plate.
