Amazing1914 I tried the trick using with phone number 22335577, it works except that the fourth digit (3 in this case) doesn't show up I get 2235577.
That's because it's an 8-digit number. Amazing's formula uses the first three and the last four numbers, so it's no surprise you're missing the first number, as you never included it. You need to use the modification for 8-digit numbers that I posted above.
