Many fraudsters think that there are only 2 types of
dumps, 101 and 201. The truth is there are many other
types of dumps. Carders usually work with either 101
or 201 but the majority will prefer 101. This is known
as the SERVICE CODE of a dump. The service code
contains 3 characters and you can find a dump service
code just by looking at a dump, regardless of the fact if
it has both TRACK1+TRACK2 and just TRACK2.
Example, let’s say we’re looking at the dump 4256
746500930321=2202101700102054. The service
code of this dump is 101, which is located right after
the expiration date of the card, which in this case is
2202 (FEB 2022). The value of the service code
determines where the cards are suitable to be used
and in what way. Below is a detailed explanation of
each service code available today.
