If your birth certificate shows the date you were born but not the time, that is normal and almost certainly not a mistake in your record. The time of birth on a birth certificate is usually captured when the birth is registered, but it is left off the certified copy most people order because the federal model that states follow does not list it among the required fields. The information still exists in the original registration on file with the state, and in most cases you can get it by requesting a different version of the certificate or by going to the hospital where you were born.
Why the Time Is Recorded but Not Printed
Every state builds its birth registration paperwork around the U.S. Standard Certificate of Live Birth, a model form maintained by the CDC’s National Center for Health Statistics. Item 2 on that form is “Time of Birth (24 hr),” and the instructions tell hospital staff to record the hour and minute on a 24-hour clock. If the time is unknown, they enter “Unknown.” They cannot leave the field blank.1CDC.gov. Birth Edit Specifications for the 2003 Revision of the US Standard Certificate of Live Birth So for nearly every hospital birth, the time is in the record from the moment it is filed.
The disconnect comes at the next step. When you order a birth certificate, you receive a certified copy, not the original registration form. The Model State Vital Statistics Act, which the federal government publishes as guidance for state vital records systems, sets out the minimum information a certified copy has to contain: certificate number, given names, surname, date of birth, state and city or county of birth, sex, and date of filing. Time of birth is not on that list.2CDC.gov. Model State Vital Statistics Act and Regulations Because most states follow the model closely, they issue certified copies without the time even though the original registration sitting in their vault includes it.
Short-Form vs. Long-Form Certificates
Most vital records offices issue two kinds of birth certificates, and the difference between them is where this problem usually gets solved.
The short-form certificate, sometimes called an abstract, is the version most people have. It contains the minimum fields: name, date and place of birth, sex, and parents’ names. It almost never includes a birth time. For routine purposes like school enrollment, a passport application, or a driver’s license, this is the version offices default to.
The long-form certificate, sometimes called a vault copy, is a reproduction of the original registration record. Because the original captured the time of birth, the long-form copy typically shows it, along with other details such as the hospital name, the attending physician or midwife, and the parents’ addresses at the time of birth.
If you need the time of birth, order a long-form copy from the vital records office in the state where you were born. When you place the order, say explicitly that you need the time of birth included, because some offices will issue the short form by default unless you ask otherwise. Fees for certified copies vary by state but generally run between $10 and $30.
How to Find Your Time of Birth
If the long-form copy does not show a time, or you need the information before a long-form order will arrive, you have a few other places to look.
The Hospital Where You Were Born
Hospitals keep their own medical records of each delivery, separate from the state registration form, and those records almost always include the time. Under HIPAA you have a right to access your own medical records held by a covered entity, but HIPAA itself does not require hospitals to keep records for any specific period; that obligation comes from state law.3HHS.gov. Does the HIPAA Privacy Rule Require Covered Entities to Keep Medical Records for Any Period of Time? State retention periods for general medical records range widely, from as few as five years to permanent preservation, and records for minors typically have to be kept longer, often until the patient reaches their mid-twenties or in some states age 30. If you are older than that, the file may have been purged. It still costs nothing to call the medical records department and ask.
Family Records
Baby books, family Bibles, personal journals, and a parent’s photos or social media posts from the day you were born can all contain the time. These are not official records on their own, but they can confirm what you learn elsewhere and can serve as supporting evidence if you later ask the state to add the time to your certificate.
The Attending Physician or Midwife
If the birth was attended by a specific doctor or midwife and your family still has their contact information, their personal records may show the time. For births more than a decade or two ago this is a long shot, but it is worth trying if nothing else turns up.
If You Were Born Outside the United States
U.S. citizens born abroad are in a different situation. Their primary identity document is a Consular Report of Birth Abroad (Form FS-240), issued by the State Department. The FS-240 is not technically a birth certificate, because consular officers do not have the authority to perform a foreign vital statistics function, and since 2013 the application form no longer collects the hour of birth.4U.S. Department of State. Consular Report of Birth of a Citizen/Non-Citizen National If you need your birth time and were born abroad, the foreign country’s own birth registration records are the better place to look; whether those records include a time depends on that country’s practices.
Amending a CRBA to add information requires Form DS-5542, a notarized application, original or certified supporting documents, and a $50 fee payable by check or money order to the U.S. Department of State.5U.S. Department of State. How to Replace or Amend a Consular Report of Birth Abroad Because the form itself dropped the hour-of-birth field, the State Department may not accept a request to add it. Contact the Passport Vital Records Section before you file anything.
Adding the Time to a U.S. Birth Certificate
If you have documentation of your birth time and want it added to your official state certificate, every state offers some form of amendment process through its vital records office. The steps look similar across most jurisdictions: file a formal application, often notarized; submit supporting evidence; pay a processing fee.
Acceptable evidence usually means hospital birth records or a signed statement from the attending physician or midwife. Some states accept other medical documentation that corroborates the time. Amendment fees typically run from nothing up to around $25, and processing takes anywhere from a few weeks to several months. Once approved, the office either issues an amended certificate or adds an annotation to the existing record. The original registration is not destroyed; the amendment is layered on top of it.
Rules on what evidence is accepted and how the amendment shows up on the final document vary by state, so start with the vital records office in the state where you were born. They can tell you which form to file, what proof to gather, and how long it will take.
When the Exact Time Actually Matters
For almost every legal and administrative purpose, the date of birth is all anyone needs. A few situations are different.
A baby born at 11:58 p.m. on December 31 counts as a dependent for the entire tax year, which can qualify the parents for the child tax credit and the earned income credit. A baby born two minutes later, at 12:00 a.m. on January 1, does not qualify until the following year’s return. The IRS allows parents to claim a child born alive at any point during the calendar year, so the timestamp decides which tax year applies.6IRS.gov. Filing Requirements, Status, Dependents A few minutes can be worth thousands of dollars, and the hospital record of the time is what settles the question.
A will or trust instrument occasionally ties a distribution to birth order or to whether a beneficiary was living at a specific moment, such as the instant of the grantor’s death. In those disputes, the exact minute of birth can determine who inherits. Lawyers in that situation go to hospital records rather than the certificate.
Outside the legal world, the most common reason people want their birth time is for an astrological natal chart, which depends on the exact position of celestial bodies at the moment of birth. That is not a legal need, but it is the reason a large share of requests reach vital records offices and hospitals.
