A server verifies that an address of record for a personal emergency response (PERS) device is in agreement with a current address of the PERS device. The PERS device has a docking station and a wearable unit. At start-up, the docking station places a call to the server and the server receives coordinates of the wearable unit. The coordinates are reverse-mapped into the current address and compared with the address of record. If the current address and the address of record differ, the address of record is updated to reflect the current address.
