Can I give my baby any last name I want in Ohio?

Published in Ohio Naming Laws 2 mins read

No, while Ohio offers some flexibility, you cannot give your baby just any last name you want. The last name you choose for your child in Ohio must match a parent's last name.

Understanding Ohio's Last Name Requirements

When registering a baby's birth in Ohio, the state has specific rules governing what can be entered as the child's last name. The most significant restriction is that the last name recorded on the birth certificate must be the last name of one of the parents. This means you cannot select a completely arbitrary last name that doesn't belong to either the mother or the father.

Permitted Characters and Formatting

Beyond matching a parent's last name, there are also strict rules regarding the characters and punctuation allowed in the name fields, including the last name. These rules are primarily due to the limitations of the state's data system for birth records.

Here's a breakdown of what's permitted and what's not:

  • Letters Only: The last name (and generally the entire name) must consist only of letters.
  • No Numbers: Numbers are strictly prohibited in any part of the name.
  • Limited Punctuation: Only specific punctuation marks are allowed:
    • Hyphens (-)
    • Apostrophes (')
    • Spaces ( )
  • No Special Characters: The data system does not permit any other special characters beyond hyphens, apostrophes, and spaces. This means symbols like exclamation points, asterisks, or other non-alphanumeric characters are not allowed.

These rules ensure consistency and compatibility within the state's vital statistics records.
