The Election Commission (EC) has prepared ballots in four different colours for each region of Thailand.
Ballots prepared for March 24 voting, and March 17 advance voting in Thailand and overseas balloting are also different.
EC deputy secretary general Nath Laoseesawakool said on Thursday that officials would undergo intensive training on March 6 and 7 to run ballot stations.
He said staff would also pay special attention to “special voters”, such as the physically challenged.
In Bangkok, a voting station, for example, will be based at the Ban Bang Khae for the Elderly so as to provide convenience for older voters.
