An identity document (also called a piece of identification or ID, or colloquially as one's 'papers') is any document which may be used to verify aspects of a person's personal identity. If issued in the form of a small, mostly standard-sized card, it is usually called an identity card (IC). Countries which do not have formal identity documents may require informal documents.
In the absence of a formal identity document, driving licences can be used in many countries as a method of proof of identity, although some countries do not accept driving licences for identification, often because in those countries they don't expire as documents and can be old and easily forged. Most countries accept passports as a form of identification.
Most countries have the rule that foreign citizens need to have their passport or occasionally a national identity card from their country available at any time if they do not have residence permit in the country.

Famous quotes containing the words identity and/or document:
“The adolescent does not develop her identity and individuality by moving outside her family. She is not triggered by some magic unconscious dynamic whereby she rejects her family in favour of her peers or of a larger society.... She continues to develop in relation to her parents. Her mother continues to have more influence over her than either her father or her friends.”
—Terri Apter (20th century)
“What is a diary as a rule? A document useful to the person who keeps it, dull to the contempory who reads it, invaluable to the student, centuries afterwards, who treasures it!”
—Ellen Terry (1848–1928)
