This was a thing, yes it was, that was then, this is now

Initially founded in 1962, the Anti-Digit Dialing League quickly became the premiere sensible dialing association organization in the United States of America. Nearly 60 years later, the problems this country’s phone network faces are direr than ever. While we continue to espouse the use of 2L+5N dialing over all-number calling whenever possible, our primary aim today is to publicly oppose the proliferation of 10-digit dialing, which is fast becoming a public nuisance and dialing nightmare for ordinary people everywhere in this country.

Circa 1962-64 (those were the days), here is the web site.  Web site?  Wait, it still is a thing!:

Although 771 is scheduled to be overlaid on D.C.’s 202 area code in 2021, forcing residents of our nation’s capitol to dial 10 digits forevermore, the A.D.D.L. objected to the use of an overlay as a matter of principle. According to NANPA, splits are unlawful when the majority of the area code is in the same rate center (as is D.C.) (see pg. 12 of Sept. 1 Community Hearing Transcript). That doesn’t mean overlays are inevitable in other areas, though. Overlays continue to remain a public nuisance, and although splits have not been commonplace since 2006, we will continue to urge the use of splits over overlays whenever possible, because splits better serve the public interest, a finding which is well supported by empirical data.
