Question

The tracking number for a package is 693840002. You mistakenly type 698340002 and get tracking information on a different package. Why was the tracking number you entered not recognized as being incorrect?

Answer 1

See below ~

Explanation:

The tracking number for the package is : 693840002

The number you have typed in is : 698340002

The place values of 8 and 3 in the tracking number have been switched. Therefore, as it is not the same tracking number, you get tracking information of a different package which corresponds to the number.
