What is required to verify a household member's date of birth when a birth certificate is not available?

To verify a household member's date of birth when a birth certificate is not available, obtaining a passport is acceptable because it is a government-issued document that contains the individual's date of birth along with other identifying information. Passports are widely recognized as reliable forms of identification, as they undergo rigorous verification processes before issuance.

Other forms of documentation, such as school enrollment records, can also contain date of birth information, but they may not be as universally accepted or as formally verified as a passport. Similarly, while government-issued letters can be credible, they may not consistently include date of birth details. Photograph IDs can help in confirming identity but typically do not provide date of birth; they are more useful for identity verification rather than establishing age. Thus, a passport is the most reliable option among those provided for confirming an individual's date of birth when a birth certificate is not available.
