Madrid (EFE) face-to-face in an office.
To be able to vote by mail it is necessary to be registered in the census of Spaniards residing in Spain (CER) or in the census of absent-resident Spaniards living abroad (CERA).
Voting by mail can be requested electronically on the Correos website, identifying yourself with the natural person certificates recognized by the Ministry of Industry and the electronic DNI, or at its offices, where it must be done personally by each voter except in the case of illness or disability.
Once the request is made, the voter will receive an envelope at home with the ballots for each political formation, the certificate of registration in the census, and another envelope with the address of the polling station where they should vote.

Once the ballot has been chosen and inserted in the corresponding envelope, it will be closed to put it in the other envelope addressed to the Electoral Table, where it will also include the certificate of registration in the census.
The vote must be sent by certified mail no later than May 24.
Spaniards living abroad have a deadline between May 20 and 25 if they vote at the polls set up in their countries or until May 23 if they do so by certified mail.
