What is the likelihood that someone would be able to guess your PIN code if they found your ATM card? It turns out that cracking your PIN code might not be as difficult as you would imagine.

People are pretty unimaginative when creating their passwords, including PIN codes.

The Yahoo! Finance article, “Cracking Your PIN Code: Easy as 1-2-3-4,” points out that there are nearly 10,000 possible four-digit combinations using the digits 0 through 9. However, over 20% of people pick one of the following PIN codes:

– 1234
– 1111
– 0000
– 1212
– 7777
– 1004
– 2000
– 4444
– 2222
– 6969
– 9999
– 3333

To be on the safe side, avoid using birthdays, birth years, street addresses, couplets (ex. 1313, 4545), and the combinations in the list above.
