Is Your Bank PIN # Secure?


In earlier posts I discussed security and scams. Numerous times I reported on credit card skimmers and how to avoid them. I also covered phishing scams.

Now here is an article discussing the PIN numbers and how we choose them. It would some of us are really lazy, or perhaps not very creative.

The article examined four digit PIN numbers that had been compromised or part of some security breach. Out of the 10,000 possible number combinations the number “1234” occurred nearly 11% of the time and was followed by “1111” and “0000”. The top 20 numbers are shown below.

PIN Freq
#1 1234 10.713%
#2 1111 6.016%
#3 0000 1.881%
#4 1212 1.197%
#5 7777 0.745%
#6 1004 0.616%
#7 2000 0.613%
#8 4444 0.526%
#9 2222 0.516%
#10 6969 0.512%
#11 9999 0.451%
#12 3333 0.419%
#13 5555 0.395%
#14 6666 0.391%
#15 1122 0.366%
#16 1313 0.304%
#17 8888 0.303%
#18 4321 0.293%
#19 2001 0.290%
#20 1010 0.285%

Another very frequent set of numbers began with “19” suggesting a birth date. This choice reduces the possible numbers to 100. Then if you were to see the real card owner, the remaining digits would be fairly simple to guess.

The whole purpose of this is to suggest that you choose a PIN number that would be more difficult to guess.

    Pardon me for going off-subject. I just clicked on the 2nd REreno, and expected to find the same blog. But it appears there are two different ones. What’s up?

      I’m not sure what the second REreno you are referring to, but I suspect that it is “REreno2” written by an interloper, I’m sure. 🙂 In reality, It is another interesting blog about the Reno real estate market. Enjoy.
