Faking a Teudat Zehut (TZ)

He's saying that you can always sign up online if you'd like.

Thanks.  That requires I guess either taking an Arabs' #, or having to try to make one up..

[yuneeq]

Its not too hard to make one up as I explained in the OP. Unless of course, I didn't do a good job of explaining.

[Moishebatchy]

Exactly.

@yuneeq.
I'm sorry to say, I tested it with a few genuine TZ numbers, some came out right, some were with remainder. what do you think?
and btw, not (at) all TZ start with 033.

I don't know if my code reading skills are that good, but I found a typical TZ validator over here https://www.golantelecom.co.il/gui_lib/_common/validators.js?rev=10006416 and it seems that I am right.

Code: [Select]

//If the input length is less than 9 and bigger than 5 add leading 0's
id_num = str_pad($id_num, 9, "0", STR_PAD_LEFT);

var counter = 0, incNum;
//: Validate the ID number
for(var i=0; i < 9; i++)
{
incNum = Number(id_num.charAt(i));
incNum *= (i%2)+1;
if (incNum > 9)
incNum -= 9;
counter += incNum;
}
if(counter%10 == 0)
return true;
else
return {
'valid': false,
'reason': 'E_INVALID',
'msg': 'M_INVALID_ID_NUM'

English works best.

[yuneeq]

I think a regular TZ starts with 03 so start the guesses from there.

@yuneeq.
btw, not (at) all TZ start with 033.

Never said it did.

[Red]

Never said it did.

They don't all start with 03 or even a 0...

[L'Chaim]

They don't all start with 03 or even a 0...

Starting with 3 is an oleh.

Oops. I found out that I explained it wrong.  It just happens to be that my results were good in my personal testing that I didn't realize that I was slightly off. The real method is explained here http://www.halemo.com/info/idcard in Hebrew. I was right until step 4.

Try reading what they say there, its actually not too difficult to understand, I think. After multiplying each of the odd numbers by 2, check to see if any of the multiplied numbers are in double digits. Those that are- add the two digits together and thats the final digit for that position. Say for example the 2nd number was 7, which gets multiplied by 2 to equal 14, add 1+4=5, now your 2nd number is 5.
After you finish single-digitizing all the numbers, add all the numbers together. If the sum is divisible by ten, you have an authentic TZ.

Yeh, I know it sounds complicated, but it definitely easier than understanding  the code that verifies it.

Code: [Select]

function add10( $num ) {
        // handles max 999
        $d100 = floor($num/100);
        $num = $num-($d100*100);
        $d10 = floor($num/10);
        $num = $num-($d10*10);

        return $d100 + $d10 + $num;
    };

    if( strlen($zehut) > 9 ) {
        return false;
    }

    $arrZehut = array();

    if( preg_match( '/(d)(d)(d)(d)(d)(d)(d)(d)(d)/', $zehut, $arrZehut ) == 0 ) {
        // Do not match
        return false;
    }


    $pos = 1;
    $s = 0;
    for( $i=1; $i<=9; $i++ ) {
        $s += add10( $arrZehut[$i] * $pos );
        $pos = 3-$pos; // pos is 1-2-1-2-1-2-1-2-1
    }

    return (( $s % 10 ) == 0 );
} // end of is_valid_zehut()

Guess I'm outgunned on this one

..And steal some fool's TZ!?
I think I'll pass on that.

[yuneeq]

Updated the wiki 

[Let3]

or easier is take an arab taxi ask him for a receipt and bam u got urself a TZ . or use ur muchedet number

nut either way thanks for the help!

1)is the meuchedet number supposed to be your reg pasport number? just checked mine- they got the last three dig off..
2) if using meuchedet number for golan (assuming its not your pasport number) you dont use the "9" beforehand correct?
(otherwise its ten numbers?)

1) Its your passport number with a 9 in the beginning. On mine, the last digit was wrong.

2) Idk, I never used it

[Let3]

so seams they get the numbers wrong often-
are there better chances of their wrong number working for phone plans over my pasport number?

Probably better chances with their number. They probably change the passport number to be a valid TZ number (like the last option in the wiki).

That.
