Angel numbers are a sign from the universe that offer insight, wisdom, and direction. They can be found throughout your daily life and are a sign of support and affirmation in that moment. Angel number 999 means expansion is happening! Did you know, you can also use your birthdate to find your unique life path number (ex: May 4, 1998). First, add all the digits together (5+4+1+9+9+8=36). Then add up the two-digit total (3+6) for your life path number (9).
