BIRTH CERTIFICATE FRAUD
FINDINGS
Fundamental, Irreconcilable Conflicts Surround Birth Certificate Purposes and Uses
A certified copy of a birth certificate is proof only that a birth occurred and was recorded.

Birth Certificates Alone do not Provide Conclusive or Reliable Proof of Identity
Many agencies and organizations request that individuals provide their birth certificates to receive a benefit or service, or to support the issuance of other documents often used for identity purposes (e.g., drivers license). However, agencies who rely on birth certificates as a means of establishing identity must understand the limitations of accepting a birth certificate as proof of age, citizenship, or identity. For example, genuine documents obtained with counterfeit birth certificates can be used to obtain genuine birth certificates. Thus, it is inherently illogical to require someone to prove their identity using potentially fraudulent identity documents spawned by false birth certificates in order to obtain a birth certificate.
