Without having chosen it, my initial phone number was a prime number of 8 digits. Unfortunately, some years later, a "1" was added before Parisian phone numbers... and my phone number became composite, multiple of 3... And if we use the international country code for France... "33"... my phone number is again obviously multiple of 3!

My social security number is prime. (Admittedly that's not terribly surprising, but it's kind of neat.)
