Identity documentAn identity document (also called ID or colloquially as papers) is any document that may be used to prove a person's identity. If issued in a small, standard credit card size form, it is usually called an identity card (IC, ID card, citizen card), or passport card. Some countries issue formal identity documents, as national identification cards that may be compulsory or non-compulsory, while others may require identity verification using regional identification or informal documents.
Civil registrationCivil registration is the system by which a government records the vital events (births, marriages, and deaths) of its citizens and residents. The resulting repository or database has different names in different countries and even in different subnational jurisdictions. It can be called a civil registry, civil register (but this is also an official term for an individual file of a vital event), vital records, and other terms, and the office responsible for receiving the registrations can be called a bureau of vital statistics, registry of vital records and statistics, registrar, registry, register, registry office (officially register office), or population registry.
Death certificateA death certificate is either a legal document issued by a medical practitioner which states when a person died, or a document issued by a government civil registration office, that declares the date, location and cause of a person's death, as entered in an official register of deaths. An official death certificate is usually required to be provided when applying for probate or administration of a deceased estate. They are also sought for genealogical research.
PassportA passport is an official travel document issued by a government that contains a person's identity. A person with a passport can travel to and from foreign countries more easily and access consular assistance. A passport certifies the personal identity and nationality of its holder. It is typical for passports to contain the full name, photograph, place and date of birth, signature, and the expiration date of the passport. While passports are typically issued by national governments, certain subnational governments are authorised to issue passports to citizens residing within their borders.
