## Abstract

Identification numbers are all around us in our everyday life; from products in the supermarket to the airline tickets that we purchase to fly across the world. We are even given our own identification numbers: through things like our driver licenses and social security numbers! But what would happen if the number was in fact incorrect? The ramifications can be minimal, or potentially serious. How then, are we able to prevent this from happening? We prevent this from happening with the use of check digit schemes, which help prevent transmission errors of any kind. In this paper, we will learn about the formulation of identification numbers, and how check digit schemes are used to prevent any errors from occurring in the transmission process. We will also see how efficient the schemes are, and where exactly their flaws lie in terms of error prevention.
