History & Origin

Zac abbreviates Zachary — Hebrew Zekharyah, 'Yahweh remembers', the prophet's and Baptist's-father's name — in the spelling that omits the usual k. Zachary's late-twentieth-century boom (presidential surname Taylor-era memory included) sent Zach, Zack, and Zac all into standalone use.

Zac remains the rarest of the three on birth certificates, with maximum sleekness. One syllable, full covenant memory.

Did you know? Zac Efron and the Zac Brown Band both skip the k — between High School Musical and 'Chicken Fried', the three-letter Zac owned a pop-culture decade.
