Overview
- Correos opened the application period on Tuesday, 6 October 2026, allowing electors to request the certificate of registration in the Electoral Census that is required to vote by mail.
- Voters must obtain the Electoral Census certificate by 19 November 2026 inclusive in order to be eligible to cast a postal vote in the 29 November general election.
- Requests can be made electronically through the Correos website using an official electronic ID or in person at any Correos office, and in limited cases a proxy may apply for someone who is medically unable to appear in person with proper authorization.
- Once provincial census offices receive requests, the election documentation will be mailed from 9 November and the last day to return a completed postal vote is 25 November 2026.
- Regional outlets reported the Correos communiqué to spread practical guidance across provinces, and officials and voters will be watching application take-up and postal delivery timing as the election approaches.
