Area code 921 is an unassigned code by the North American Numbering Plan Administrator. Although it is registered with NANPA, it is not a valid area code. It can also be laid out as an expansion code for future use if it gets necessary to expand the current 10-digit phone number format. Around 340 unassigned area codes in the United States are supposed to be used for general purpose area codes in the future or are planned to be used as overlaid area codes to meet the demand for increasing phone numbers in a state, city, or region. This shrinking phone numbers available for distribution is called “number depletion”.
