For decades, Californian state law has forbidden the use of accent marks, hyphens, tildes, umlauts, and other diacritical marks on official records, including birth certificates.
Despite being one of the most linguistically diverse places in the world, California’s official documents still strip names of their native spelling. This is the result of a decades-old rule based on system compatibility, and a rigid interpretation of English-only data standards.
Proposition 63: The Law That Erased Accents
The prohibition dates back to Proposition 63, passed by voters in 1986, which declared English the official language of California.
This policy was followed by statewide standardization efforts across agencies like the Department of Public Health and the Office of Vital Records.
In practice, this meant removing any characters not included in the basic English alphabet. Diacritical marks — such as á, é, ñ, ö, and ç — were deemed incompatible with state systems, and are still classified as “unacceptable entries” on vital records.
The result is a statewide inability to accurately represent names from dozens of cultures on documents that serve as the foundation of a person’s legal identity.
How Proposition 63 Affects Birth Certificates
For birth certificates specifically, the impact is immediate and permanent.
When a baby is born in California, parents are legally not allowed to include accents or special characters in their child's name.
Even when handwritten correctly on the application form, the final certified birth certificate will be printed without them. And there’s currently no legal way to have the record amended to restore the correct spelling.
For example, a child named José Luis Muñoz will appear in state records as Jose Luis Munoz, even if that’s not how his family, school, or passport spells it.
Why the State of California Maintains the Ban
California’s stance isn’t just a cultural oversight, it’s also a technical and bureaucratic issue.
The systems used by the Department of Public Health and local registrars were designed around legacy databases that often reject or misread special characters.
State officials have historically argued that allowing diacritical marks could lead to data mismatches with federal agencies like the Social Security Administration, which also strips accents from its records.
In addition, the California Association of Clerks and Election Officials has expressed concerns about the high cost of reprogramming legacy systems. Previous estimates for upgrading databases to allow diacritics have ranged from $5 to $10 million statewide.
The Consequences of Standardization
The impact of this policy goes beyond minor formatting. It affects identity verification, school records, passports, and even employment documents.
In some cases, names with and without accent marks are considered entirely different names in their original language. For example, the name Nicolás is not interchangeable with Nicolas. Yet in California’s birth registration system, they are treated as one and the same.
For many families, especially Latino, Vietnamese, French, German, and Indigenous households, the inability to preserve accurate names on a birth certificate is a painful contradiction in a state that otherwise celebrates cultural diversity.
A Move Toward Change: AB 64
After several failed attempts in past years, Assembly Bill 64 (AB 64) (also known as the Identity Integrity Act) is the latest legislative push to reverse the ban.
Introduced by Assemblymember Blanca Pacheco in 2024, the bill would require the California State Registrar to accept diacritical marks on vital records, including birth certificates, death certificates, fetal death certificates, and marriage certificates.
AB 64 also includes provisions to let people request corrected certificates if their name was previously recorded without its proper accents.
When will the new bill be enacted?
The bill passed out of key committees in 2025 and, if enacted and funded, could begin implementation as early as 2027. Counties would be given time and funding to modernize their systems to accommodate the changes.
Supporters argue it’s long overdue. “Names are part of who we are,” said Pacheco in a public statement. “We should not have to erase our identity at birth.”
California’s Move Toward a More Accurate Record of Identity
California’s refusal to allow diacritical marks on birth certificates is a relic of outdated policies and aging technology.
While the original intent may have been to preserve consistency across systems, the result has been a systemic erasure of linguistic and cultural nuance from some of the most fundamental documents in a person’s life.
If AB 64 becomes law, Californians may finally gain the right to spell their names correctly on their birth certificates — a small but deeply meaningful change that affirms identity from the very beginning.
