DROP YOUR PHONE NUMBER

The digit 0 = 64
Z + E + R + O = 64, for instance
(26 + 5 + 18 + 15 = 64)
Trust me, I used to work with an NSA code breaker.
I merely assign all the letters of the alphabet by their corresponding numbers.
Five and Nine both equal 42 (do the math yourself, if you want).
So, by adding all the digits in my phone number, and totaling them all up, that comes to 545.
Now, anyone who can crack that code deserves to know my phone number!
Good luck and happy code breaking
