The FS-545 form is a Certification of Birth previously issued by U.S. Department of State consulates. It is often submitted together with the prior version of the FS-240 form or a Consular Report of Birth Abroad.
U.S. consulates stopped issuing FS-545s after Nov. 1, 1990. Although the forms have been discontinued, all previously issued FS-545s are still considered valid as proof of citizenship and identity and for other legal purposes. The FS-545 is often submitted to establish U.S. citizenship and the identity of any U.S. citizens born abroad. Any U.S. citizen who has given birth in another country before Nov. 1, 1990 can also use the FS-545 to report the birth of the child to any U.S. Embassy or consulate.
