Is Your Blood Type on Your Birth Certificate? What Most States Show and the New Jersey Exception

In most places, no. The birth certificate you hold is unlikely to list your blood type. The notable exception is New Jersey, where state law says the certificate of birth shall include the blood type of the child.

If your certificate does not show it, you have other ways to find out, and none of them involve ordering a new certificate.

Choose your certificate to start your order.

What New Jersey law says

New Jersey Statutes Section 26:8-28 sets out what must be filed within five days after a birth. Subsection d. is a single sentence: "The certificate of birth shall include the blood type of the child." That makes New Jersey one of the few states with a written requirement we could find.

Because that text comes from a legal publisher's copy current as of January 2024, check the New Jersey legislature's site or the state vital records office for the latest version. If you were born in New Jersey, ask the vital records office whether your own certified copy prints a blood type.

What about other states?

We did not find a blood type requirement in the other state sources we reviewed for this site. The standard national birth certificate model, the U.S. Standard Certificate of Live Birth published by the National Center for Health Statistics, is the form many states build from. If you want to know for sure whether your own state prints a blood type, look at your certificate or ask the state vital records office. Your own document is the final word.

How to find your blood type

  1. Check your own medical papers. Any record of a past blood test may list your type.
  2. Ask your health care provider. A doctor can order a blood test, and the result will show your type.
  3. Donate blood. The American Red Cross says donors can create an account to see their blood type, among other health results.

Frequently asked questions

Does a birth certificate show blood type?

Usually not. New Jersey law says the certificate of birth shall include the child's blood type, but we did not find that requirement in other state sources.

Which state puts blood type on the birth certificate?

New Jersey, under Section 26:8-28 of its statutes. Ask the state vital records office whether your own certified copy prints it.

Where can I find my blood type if it is not on my birth certificate?

Try old medical records, ask your health care provider for a blood test, or donate blood. The Red Cross says donors can see their blood type in their donor account.

Can I add my blood type to my birth certificate?

We did not find a state process for adding a blood type to a birth certificate. Contact your birth state's vital records office to ask.

Why is my blood type missing from my birth certificate?

We found a written requirement only in New Jersey. If your certificate does not print a blood type, check with your birth state's vital records office.
