The prime factors of my work phone number 7255393 are 2389 and 3037, making the phone number effectively a tiny RSA public key. I was inspired to discover this when Raphael Fernandez pointed out that 8675309 is prime. All of my family's and my other phone numbers are even. So is my SSN. My Driver's License Number is divisible by 7. So my work phone is the only primally interesting number that I can think of offhand that I own. (B)
