I learned something new about Excel today: the maximum number of digits in a number that you can have accurately in a cell is 15. Yes, there is a reason for it (an IEEE standard) and there are ways around it (format the cell as Text or turn on "Precision as Displayed").

A coworker was entering USPS Tracking numbers that were 19 digits and the last four digits were turned into zeroes. Did a little research and this is what I learnt. For our purposes, formatting the cells as Text worked just fine. From browsing the link below, I am not sure of the overall impact of turning on "Precision as Displayed."
