A warrant card is proof of identification and authority carried by police officers. The term is normally used only within the United Kingdom and in current and former Commonwealth countries. Many other countries refer to their equivalent of warrant cards simply as police credentials, commission books, or identification cards.
Warrant cards generally include a photograph of the holder, as well as the holder's name, rank, warrant number and a holographic emblem to mark authenticity. The warrant number is equivalent to a badge number in other police services; it is a unique identifier unlike a collar number (sometimes displayed on the uniform) which may change when transferring between departments or changing rank. A warrant card is sometimes displayed alongside a badge showing the service to which the officer belongs, but is increasingly commonly displayed on one ID card, with the force crest printed on it.
The language on a warrant card usually indicates that the holder is granted authority by a specific official to perform the functions of the office held, and may also indicate training to a particular level. In the UK Police personnel authorized to carry firearms may have an endorsement on their warrant card to that effect.
Police officers in plain-clothes are required to identify themselves and produce their warrant card when they are performing their police duties and exercising their police powers, so long as it is practicable to do so (i.e. not if the person they are arresting is being violent). Generally, police officers are required to produce their warrant card when requested, even in uniform, but only if it is practicable.
Famous quotes containing the words warrant and/or card:
“Sometimes, when I compare myself with other men, it seems as if I were more favored by the gods than they, beyond any deserts that I am conscious of; as if I had a warrant and surety at their hands which my fellows have not, and were especially guided and guarded. I do not flatter myself, but if it be possible they flatter me.”
—Henry David Thoreau (18171862)
“What is the disease which manifests itself in an inability to leave a partyany party at alluntil it is all over and the lights are being put out?... I suppose that part of this mania for staying is due to a fear that, if I go, something good will happen and Ill miss it. Somebody might do card tricks, or shoot somebody else.”
—Robert Benchley (18891945)
