Is It Illegal Not to Have a Name?

In the United States, no matter where a woman gives birth, she is legally obligated at some point to report it to the appropriate government entity, usually a department of health and human services or vital records. That entails filling out a first and last name for the child. How long the mother has to fill out that birth certificate varies by state.

Contrary to popular belief, you don't have to give your baby a name before leaving hospital. In the absence of a name, hospitals will assign a name like "Babygirl Smith" to your baby, though a 2015 study showed that using a more distinctive naming pattern like "Janesgirl Smith" (for the daughter of Jane Smith) could reduce "wrong-patient errors" in the facility.

Even in the absence of a name, the hospital will still register your baby's birth and send the info to your state's health department. (You can get a copy of the birth certificate from your state or county's department of vital records.) The procedure for adding a name later may vary depending on the state you live in.

For instance in California, you have to request a "supplemental name report" form from your health department, fill it out with your baby's name and then send it directly to the birth registry (vital records). You have a year to do this without a fee.

Although naming customs for babies differ across the world, all countries have some sort of vital records collection, whether centrally or locally controlled. In fact, Article 7 of the United Nations Convention on the Rights of a Child states that all children have a "right from birth to a name" [source: United Nations].

But if you pick something too off the wall, beware. In 2007, the New Zealand government revoked Pat and Sheena Watson's name selection for their son. The offender? 4Real. Like the United States, New Zealand does not allow the presence of numerals in legal names.

German parents must follow stricter standards enforced by the local registration office, called the Standesamt. They must select a moniker that reflects the baby's sex and will not incite ridicule for the child [source: Gesley]. Iceland has similar laws and a list of approved names. In Zambia, boys and girls are expected to change their names at puberty and may go through several names during their lives [source: Tembo].
