Alex: There's a mistake. 22 is not "double 2" but "Twenty-Two". . The others are "Two Hundred Twenty-Two" and "Two Thoudand, Two Hundred Twenty-Two" .

When talking about a quantity: 22 - Twenty-two 222 - Two hundred twenty-two 2222 - Two thousand two hundred twenty-two When saying a phone or card number: 22 - Double two 222 - Triple two 2222 - Double two, double two (or quadruple two)
