Spammer to switch electric companies. Comes up as "unknown name." Called me 14 times over a week's period. I finally figured out how to block the number. It comes up as 837-436-53420, with an extra "0" at the end in my Verizon online call record, but without the extra zero on my phone's Caller ID display.
Area code 837 belongs to CALIFORNIA, UNITED STATES. It is a General Purpose Code which was placed in service on 2025-01-31.
