Whether your birth weight is on your birth certificate depends on which version of the certificate you have. The long-form (also called the certified copy of the original record) sometimes lists it; the short-form summary almost never does. Birth weight is recorded on the underlying U.S. birth record in every state, but what prints on the document you receive is up to the vital records office that issues it.
Long-Form and Short-Form Certificates
Most states produce two versions. The long-form is a certified copy of the original birth record and carries the full set of details the hospital reported. The short-form is an abstract that confirms the birth and lists legal essentials like your name, date of birth, place of birth, and parents’ names, but strips out the medical data.
Birth weight, length at birth, and time of birth sit in a category VitalChek describes as “vital statistics” that each state’s vital records agency can choose whether to include.1VitalChek.

If birth weight is specifically what you need, request the long-form and call the issuing state’s vital records office first to confirm their long-form actually prints medical data before you pay.
Why Birth Weight Is on the Underlying Record
The U.S. Standard Certificate of Live Birth, maintained by the National Center for Health Statistics at the CDC, is the template every state builds its own birth record from. Alongside the legal identification fields, it collects a long list of medical data: birth weight, obstetric estimate of gestational age, Apgar scores, method of delivery, abnormal conditions of the newborn, and the mother’s prepregnancy weight, among others.2Centers for Disease Control and Prevention.

So the data exists in the system for every U.S. birth. Whether it travels onto your paper copy is a separate question, decided at the state level.
How to Order a Long-Form Copy
Birth certificates are issued by the vital records office in the state where the birth took place. Each state runs its own process, so forms and fees are not uniform. Most states let you order online, by mail, or in person. Many contract with VitalChek as an authorized online vendor, which can be faster but adds a service fee on top of the state’s charge.4VitalChek. Order Birth Certificates Online
A few practical points when ordering with birth weight in mind:
- Specify the long-form (sometimes called a “certified copy of the original record” or “full copy”). Short-form, abstract, or wallet-size versions will not help you.
- Call or email the state office before paying and ask whether their long-form certificate shows birth weight. Staff can answer this quickly.
- State fees for a single certified copy range from around $10 to over $30, with extra charges for expedited shipping and for ordering through a third-party vendor.
- You will need a valid government-issued photo ID. Most states restrict who can order to the person named on the certificate, a parent, a legal guardian, a spouse, or a legal representative; some extend eligibility to grandparents and siblings.
Other Ways to Find Your Birth Weight
If the long-form in your state doesn’t show birth weight, or you’d rather not order another copy, a few other sources are worth checking first.
The hospital where you were born keeps medical records that include birth weight, length, and other delivery details. Contact the hospital’s medical records department and ask for the delivery record or newborn admission record. You will need to verify your identity. If the birth was decades ago, be aware that some hospitals move older records to off-site storage or microfilm, which adds processing time.
Your mother’s prenatal and delivery records, if she still has them, often contain the number. Baby books, baptismal records, and early pediatric charts frequently note birth weight as well. Any of these can save you a vital records fee.
Fixing a Wrong Birth Weight
If birth weight does appear on your certificate but it’s incorrect, you can request an amendment through the vital records office that issued the document. The process generally involves a formal application, supporting evidence of the correct figure, and a processing fee.
For a medical data point like weight, the most persuasive evidence is hospital records from the time of birth. Vital records offices also commonly accept baptismal records, early school records, census records, and military records. Affidavits from people with firsthand knowledge can support an amendment, but offices treat them as less reliable than records created close to the date of birth.
Amendment fees range from nothing to around $50, and many offices issue one corrected copy at no additional charge once the amendment is processed. The process usually takes several weeks. Submit original documents or certified copies, not photocopies.
