To find out the number of unique IDs:

Given, assigned unique id= 9 digits.
Unique numbers= 1,2,3,4,5,6,7,8,9,0

Then,

n = 10
unique number: r = 9 digits

Using formula:

[tex]\begin{aligned}\rightarrow{ }^n P_r=\frac{n !}{n-r !} \\\rightarrow P_9^{10} &=\frac{10 !}{(10-9 !)} \\&=\frac{10 !}{(10-9 !)} \\&=\frac{10 !}{(1 !)} \\&=\frac{10 !}{1} \\&=3628800\end{aligned}[/tex]
