RIO DE JANEIRO - Tickets for the Rio 2016 Olympics went on sale to Brazilian residents on Tuesday via the Games' official web portal.

Local fans have until April 30 to request tickets in the first draw with results to be announced in June, organizers said on Tuesday.

Only those who applied for the first installment will be eligible for the second draw in July.

Meanwhile non-residents are now able to see a list of authorized ticket resellers (ATR) in their region.

"Each ATR will have its own sales process and fans should seek this information from the company that will sell tickets in their territory," said Rio 2016 ticketing director Donovan Ferreti. "Any ATRs who are approved after 31 March, will be added to the list subsequently."

About 7.5 million tickets for the Rio Olympics will be put on sale, with more that half being priced at 70 Brazilian reais (about $22) or less.

The cheapest sports event tickets will be 40 Brazilian reals (about $13) and the most expensive 1,200 Brazilian reais. Seats for the opening ceremony at the Maracana stadium will cost 4,600 Brazilian reais.
