Except in the State of Aguascalientes, the State Archives and local civil registries
for the capital cities are separate offices.
State Archives certificates are issued in the city in which the State Archives is
located. For instance, a document issued by the “Oficial del Registro Civil, Villa
de Ramos, S.L.P.,” was issued by a local civil registrar.
The format of the certificates issued by State Archives and the titles of the officials
issuing the certificates vary from State to State and often between administrations.
GN 00312.258 lists the names and addresses of the State Archives in each State in Mexico.
