Page "Premium-rate telephone number" Paragraph 7

Premium rate numbers start with the prefix 060 followed by 7 or 8 digits.

Some consumers do not know that numbers starting with 060 are premium rate numbers because 060 is mistaken for one of long-distance area codes in Korea ( there are 062, 061 and 063 ).

They call back when they find that they miss a call to their mobile phones from a 060 number ending up paying for just making a call.
