A job requisition number is a set of numbers or letters attached to a specific job opening on a website. The numbers are used by recruiters as a way to keep track of applicants that apply to various positions.
Job requisition numbers are also useful to potential applicants who need to keep their applications orderly. When a company or business wants to advertise for multiple positions that have the same title, they may use job requisition numbers to indicate that more than one opening is available. Also, an employer may request that an applicant forward their application or resume along with the job requisition number rather than the title of the position.
