How Many Unique Numbers Between 100000 And 999999

I need a list of unique numbers that contain 6 numbers between 100000 and 999999
i need the max of it
i used this website to generate those numbers https://numbergenerator.org/


But after I get the numbers I pass it into duplicate line remover and it removes


so I find myself always left with only 603531 numbers when it should be 899999
