Charish Persico, 24, from Merritt Island, welcomed her son Carter Kerr at Health First's Cape Canaveral Hospital in Cocoa Beach on Sunday afternoon.
'They announced the time of birth at 15:21 in military time. I'm sitting there laying and going through my head, and I said, "It's 3:21,"' the new mom told Good Morning America.
Not only did the numerology of his birth date and time match up, but the hospital is located in Brevard County's 321 area code.
'My mom said, "You just had your baby on 3/21 at 3:21,"' she recalled. 'Then my doctor said, "And you're in the area code 321!"'
Charish had a C-section scheduled for March 26 because Carter was breech, but it was moved up after she started having contractions on Sunday.
Arriving five days early, Carter weighed 8 pounds, 12 ounces and measured 19 inches long at the time of his birth.
The hospital also pointed out that Carter's room overlooks Florida's Space Coast, where NASA crew members count '3-2-1' before launching rockets.
Charish said she and Carter's father, Justin, are 'over the moon' and have already started collecting newspaper clippings of their baby boy's headline-making '321' birth.
'Meet the 321 Baby!' the caption reads. 'Carter Kerr was born at Health First’s Cape Canaveral Hospital at 3:21 p.m. on 3/21 in the 321 area code.
'Weighing in at 8 pounds, 12 ounces and 19 inches long, first-time parents Charish and Justin could not be more excited.'
