Telephone area codes in Palm Beach County, Florida

**Area codes 561 and 728** are telephone [area codes](/source/NPA_code) in the [North American Numbering Plan](/source/North_American_Numbering_Plan) (NANP) for [Palm Beach County](/source/Palm_Beach_County%2C_Florida) in the [U.S. state](/source/U.S._state) of [Florida](/source/Florida). 561 was created on May 13, 1996, in a split of [area code 407](/source/Area_code_407). The numbering plan area (NPA) comprises nearly every major city in the county, the largest of which being [West Palm Beach](/source/West_Palm_Beach%2C_Florida), [Boca Raton](/source/Boca_Raton%2C_Florida), [Wellington](/source/Wellington%2C_Florida), [Boynton Beach](/source/Boynton_Beach%2C_Florida), [Jupiter](/source/Jupiter%2C_Florida), [Delray Beach](/source/Delray_Beach%2C_Florida), and [Belle Glade](/source/Belle_Glade%2C_Florida). On March 10, 2023, area code 728 was added to the same numbering plan area to form an all-services distributed [overlay](/source/Overlay_plan).[1]

Within only five years of creation, NPA 561 was experiencing rapid exhaustion of central office codes from growth of service demands in the Palm Beaches/[Treasure Coast](/source/Treasure_Coast) region and the proliferation of cell phones. In mitigation, the northern part of 561, the Treasure Coast, was split off with [area code 772](/source/Area_code_772) in 2002. This service configuration in the region was sufficient for twenty-one years until on January 4, 2022, the Florida Public Service Commission approved an all-services overlay for the NPA, with an effective in-service date of March 10, 2023.[2]

A permissive dialing period was not necessary for this overlay, because area code 561 already had a [ten-digit dialing](/source/Ten-digit_dialing) requirement, because prior to October 2021, it had telephone numbers assigned for the [central office code](/source/Central_office_code) 988. In 2020, *988* was designated nationwide as a dialing code for the [National Suicide Prevention Lifeline](/source/National_Suicide_Prevention_Lifeline), which created a conflict for exchanges that permit [seven-digit dialing](/source/Seven-digit_dialing). Calls with the numbering plan area therefore required ten-digit dialing by October 24, 2021.[3]
