Under rules approved by parliament and signed into law earlier this month, Poles have the option of voting by either by post or in person.
Polling stations are open in Poland from 7 a.m. to 9 p.m.
A record 387,000 Poles living abroad have registered to vote by absentee ballot in the country's presidential election, Deputy Foreign Minister Piotr Wawrzyk said on Wednesday.
The State Electoral Commission (PKW) will hold four press conferences, at 10 am, 1:30 pm, 6:30 pm and 10 pm on Sunday to present turnout figures, and to provide information on the course of voting and on any possible incidents.
A ban on electioneering, publication of opinion polls and promotion of individual candidates or lists, including online, came into force at midnight on Friday and will last until the end of voting.
After the vote, the TVP, TVN and Polsat national television stations will present results of exit polls, which will be conducted by the Ipsos pollster outside 500 randomly selected polling stations.
PKW head Sylwester Marciniak recently told PAP he expects the announcement of the official result of the Sunday vote on Wednesday, July 1, at the latest.
If none of the eleven contenders in the race wins more than 50 percent the vote, under Polish election rules, a second round will be held on July 12. (PAP)
