Area codes 619 and 858 used to cover different areas of San Diego county. Back in 2017, due to telephone number exhaustion projections by the California Public Utilities Commission for NPA 619, it was decided it was time to eliminate the boundary between the two area codes, the move resulting in a new overlay complex 619/858. This decision was put into practice on June 19, 2018.
