  • The first three digits were historically (before mid-2011) assigned by geographical region, and are thus called the area number. The area number cannot be 000, 666, or between 900 and 999.
  • Digits four and five are called the group number and range from 01 to 99.
  • The last four digits are serial numbers from 0001 to 9999.
