The ESN is a unique identifier assigned to each mobile device. It helps carriers and manufacturers track the device’s history, including activation status and any reported issues. Verifying the ESN ensures that the device is not reported as stolen, lost, or blacklisted, which could prevent activation or lead to future problems.
