Zack
A short surname that usually comes from a pet form of names like Zachary or Zacharias.
The #7,983 most common surname in the United States (2010 Census) — about 1 in every 74,558 Americans shares it.
Etymology
Zack is most often understood as a shortened form of given names such as Zachary or Zacharias, ultimately from the Hebrew name Zechariah, meaning "the LORD has remembered." In English and German-speaking contexts, it can also appear as a clipped surname from similar Bible-based forenames. In some cases, especially in Germanic records, it may simply reflect a nickname or shortened family name built on the same sound.
History
The surname is comparatively uncommon and is most often found in Anglophone settings where short, clipped surnames became fixed from earlier given names. Its use likely expanded through the popularity of biblical personal names and later immigrant record-keeping, which often standardized shorter forms like Zack. Because it is brief and phonetic, it may also appear as a spelling simplification of longer related names.
