It gets worse for a phone number. If you enter the UK phone number 0141 404 2559, not only does the zero disappear but 1,414,042,559 is a really big number, well over a billion. So if you put it in Excel, it might switch the number over to a different way of writing numbers: scientific notation. I just pasted that number into a spreadsheet and now all I can see is 1.414E+9.
