The method for reducing the rate of registration in CDMA-based mobile networks is a method for preventing a traveling mobile device from registering within a new, or secondary, registration area, prior to physically relocating from a first, or current, registration area to the new registration area. The mobile device has a storage memory associated therewith, for storing a database containing geographic coordinates defining boundaries of a plurality of registration areas. The mobile device scans for a new registration pilot signal associated with a new registration area, and upon detection, the geographic location of the mobile device is determined. This geographic location is compared with the coordinates of the boundaries stored within the database, and if the mobile device is determined to be within the boundary defining the new registration area, the mobile device is then registered with a base station of the new registration area.
