1. ## [SOLVED] Help with this puzzle

See if you can figure out the code using only these data.

752750175 = ||...|.|.|...|.||...|.|.|.||......|||...|.|.|....| ||

168026300 = |...||.||..|..|.||.....|.|.||....||.||...||....|.. ||

856217314 = ||..|..|.|..||....|.|...|||...|..||....||.|..|..|| .|

What is the pattern? What are the rules? Explain how you got it.

What is the code for each digit, especially 9 which does not appear in the data set?

Look at this:

75 is present in the array 3 times.

We know that 7 starts with ||... etc etc

Comparing the first 75 with the last one however, there seems to be some problem:
Code:
First:  ||...|.|.|...|.||

Second: ||...|.|.|....|||
I'm assuming you made a typo, but this is already a start. From here you can distinguish between 7 and 5 and so forth until you have succeeded in deciphering the entire first number.

Also, there are 22 lines and 30 dots in each of the three. And a space between the 2nd and 3rd from the last on all three. I looked at this a while, but couldn't come up with anything better than that. However, it seems unlikely that there is a straight number to code translation, because there are 9 digits but 52 code units (53 if you include the space)

4. I'm curious as to what this is for...

Hacking government security network?!?!?! OH NOZ!

Someone go find us a Navajo.

No i don't think government security would be that easy. This is way too easy to crack. I'll crack it within 30 minutes if i sat with it and did it.

What's a Navajo?

What's a Navajo?
During World War 2, the U.S. Military brought Navajo Indians on board. They made a code that involved translating from Navajo to English then using the English words to decipher the code.

8. Looks like the US Postal bar code, for any ZIP+4 code.

This should explain it: How to Read Postal Bar Codes

Your examples do not use the "Last 2 digits of Street Address" section, but do use the Check Digit.

You're right, that's why I didn't figure it out earlier, I thought about the first and last being "frame bars" but didn't figure the last 5 went to an invisible digit.
