Honestly, I thought this was already a thing. Apparently, it wasn’t. Beginning April 24, 20201 Delawareans will have to dial the area code 302 before any local phone number thanks to a change by the FCC. 10-digit local dialing. 6ABC says the change is due to a new FCC order, which approved 988 as the 3-digit abbreviated dialing code to reach the National Suicide Prevention Lifeline, starting July 2022.
