What this means when you pick up the phone.
Local calls inside 808 may still work on seven digits, but ten-digit dialling is the safe default everywhere in the country now. From abroad, dial +1 then the ten digits.
How Honolulu came to have one area code
Why one city can carry several codes.
Area codes are assigned to geography, then exhausted as demand grows. Honolulu — population about 351k — is covered by code 808, 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.
