Proof of Age: Documents That Show Your Date of Birth

Proof of age is an official document that shows a person's date of birth. A birth certificate is the most common one, but schools and agencies often accept other records when a birth certificate is not available.
What vital record do you need?
Choose your certificate to start your order.
For Social Security
The Social Security Administration (SSA) ranks evidence of age by how reliable it is. Its operations manual puts a public record of birth, or a religious record of age made before age five, at the top as preferred evidence. If that is not available, the SSA looks at other listed documents and then at combinations of documents.
For school
The U.S. Department of Education says school officials may ask for documents showing a student meets the district's minimum and maximum age. Districts typically accept alternatives to a birth certificate, such as a religious, hospital or physician's certificate showing the date of birth, a family Bible entry, an adoption record, a parent's affidavit or earlier school records. A district may not prevent or discourage enrollment because a child lacks a birth certificate or has a foreign one.
Texas offers an example. Its pre-K enrollment rules list a birth certificate, a passport, a hospital birth record, adoption records, a church baptismal record and school records, among others. Parents can also request a statement of date of birth from the state vital statistics office for school admission, free when marked for school admission.
Frequently asked questions
Does my child need a birth certificate to enroll?
The Department of Education says a district cannot keep a child out of school for lacking one. Districts typically accept alternatives. State and local rules differ.
Is a verification letter the same as a certified copy?
No. Texas notes that its verification letters are not legal substitutes for certified copies of a birth certificate.
What does the SSA prefer?
A public birth record or a religious record of age made before age five.
