How Des Moines came to have one area code
Why one city can carry several codes.
Area codes are assigned to geography, then exhausted as demand grows. Des Moines — population about 210k — is covered by code 515, drawn from within 25 miles of the city centre. A single code still has enough numbers for the area, so no overlay has been needed yet. When growth exhausts it, regulators will layer on a new code and local calls will move to ten digits.
