Why are you even doing that? You don't need to do any of that for a full account anymore or to use cash shop...
This guide is old.
If you are a simple member (someone who just made an account) go here:

After that fill in the form:
First box = WA nickname: put any nickname here
Second box = Real name: Put your name here if you want or make a fake one
Third = ID number: now this is the number/password you need to change your password so keep it safe. Can be any combination of numbers and letters.
Fourth = Date of Birth: Self explanatory
Fifth = Mobile number: Start it with 09 and then any combination of numbers. You need 11 numbers in total.
Sixth = Home number: Start with 02 and then do the same. This time it is 10 in total.
Seventh and Eight Is your address: Top line is postal code/zip code. Put any numbers in here: i always put 123
Then next line underneath is street name: "dragonball online street" is what i use.
The tick box is for them to email you. Don't bother with that.
