The Commission on Elections has published the designated common poster areas for the special election in the lone congressional district of Batanes. Candidates and their supporters may mount campaign materials only inside these spots. Materials can go up strictly during the campaign period, which runs from October 28 to November 26, 2026. Common poster areas are meant to spare public and private property from election clutter while giving every candidate the same posting ground. Posting outside the allowed places and dates counts as a campaign offense. The special polls will fill the island province's single seat in the House of Representatives. Comelec typically releases the site locations early so village officials can help enforce the rules.
