In August 2022, Expansión reported the position of the Ministry of the Interior: “El acta de nacimiento no tiene vigencia” (The birth certificate has no expiry). The same article noted that some government procedures still ask for a birth certificate issued on a defined date.
In July 2026, Expansión returned to the question. Mexico City and Oaxaca said that their procedures would not require recent copies. The newspaper also reported that since April, the state government of Michoacán had required a copy less than two years old.
