It is 17.
The smallest ten-digit number that has two digits the same is 1000000000. However, this number does not meet the requirement of having two digits the same. The smallest valid ten-digit number with two digits the same is 1000000001, where the digit '0' appears eight times and '1' appears twice.
The smallest 7-digit number with no two digits alike is 1023456. This number begins with the smallest non-zero digit (1) to ensure it remains a 7-digit number, followed by the smallest available digits (0, 2, 3, 4, 5, and 6) arranged in increasing order.
There are only two smaller 3-digit numbers and both of them have repeated digits.
