Bangkok: There is no advance voting in the upcoming referendum as the law mandates only one designated day for voting. This legal stipulation ensures that exceeding the set timeframe could render the referendum invalid. Despite this, the law facilitates voting outside one's province on the same day as the primary referendum, allowing voters to cast their ballots anywhere in Thailand on February 8th, without the need to visit their designated polling station.

According to Thai News Agency, combining elections and referendums on a single day could impose a burden on the public. The principle of "time and place" typically governs advance voting for parliamentary elections, allowing voters the flexibility to cast their votes before election day and at any location. However, treating elections and referendums as distinct events places a strain on voters, as referendums impose no time constraints, only location requirements. Thus, individuals who register for advance voting for parliamentary elections on February 1, 2026, are still required to participate in the referendum on February 8, 2026.

To ensure voters do not lose their rights, guidelines have been established for registering for parliamentary elections and the referendum. Voters are advised to exercise their right to vote in both parliamentary elections and the referendum on February 8th, as both will occur at the same polling stations. Voters can register for advance voting on February 1st and cast their referendum vote outside their province on February 8th.

Moreover, those who only register for advance voting in parliamentary elections and fail to register for the referendum vote outside their province on February 8th must inform the authorities of their inability to vote in order to avoid restrictions on their voting rights. Changes or cancellations to registration can be made within the registration period, with a deadline set for January 5, 2026. This information was shared on the Facebook page of Saeng Boonmee, Secretary-General of the Election Commission (EC).
