A person who submits a formal written request to a business, college government, or other legal entity is known as an applicant. A job, a legal remedy for an issue, or any other kind of specific request can all be made by an applicant. A person selected for a particular position or opportunity can also be referred to as an applicant. To put it simply, an applicant is the one who submits an application. As an applicant, he or she has an Applicant ID, a special identification number.
