What is document number nedir?

Document number refers to a unique identifier assigned to a specific document, such as a contract, invoice, or receipt. It is a combination of letters and/or numbers that distinguishes the document from others for record-keeping purposes. This number usually appears on the document's header or footer and is used to locate and track the document's information in a database, making it easier to manage and organize paperwork. Document numbers also help reduce errors and prevent duplication of documents. In some cases, document numbers may be used as a reference when communicating with suppliers or customers.
