What an 878 number signals to a caller

An 878 number has been around since 2001, yet locals still describe 412 as the badge. "412" appears on t-shirts and in rap lyrics, and some businesses hold the older code the way others hold a vanity plate. Practically the two work identically. Callers describe Pittsburgh phone manners as friendly but unpretentious: people answer plainly, small talk is genuine rather than performed, and overselling reads badly in a city that watched its dominant industry collapse and rebuilt anyway. Modest claims, kept, go further here than big ones.
