The tracking efficiency is a relevant systematic uncertainty for analyses using charged particles. The current Belle II result is a single number. Our goal is to determine the tracking efficiency as a function of the momentum magnitude, the polar angle and the charge to be able to achieve more precise results in analyses. I will present the analysis procedure and the results.
