Bates numbering is a method of sequentially numbering pages with a reference identifier to make them easier to locate and reference. This could be as simple as sequential numbers like “0001” and “0002,” or it may include alphanumeric strings (such as “ABC_0001” and “ABC_0002”). Also referred to as “Bates stamping,” Bates numbering is commonly used in the legal industry for indexing and tracking large volumes of documents—such as with litigation activities like discovery and trial preparation.
