For years, Salidans used four digits when exchanging phone numbers: the 539 prefix was just assumed, as in “we’re at 5345.” That has changed with growth — now there’s 530, as well as 221 for cellular telephones.
Now the Crestone-Moffat area in Saguache County, served by the Columbine Telephone Co., is undergoing a similar change.
There the custom was three digits, with the 256-4 assumed. Henceforth they’ll need four, because most new numbers will be assigned from the 256-5 block.
