Polling will be open Saturday and Sunday from 9am to 9pm, according to each country’s local time.
Embassies in New Zealand, Australia and China have already begun polling, with other countries expected to open soon.
Polling stations will be available in 139 countries, excluding Yemen, Syria, Libya and the Central African Republic due to their “security situations.”
Egyptians at home will be able to vote in 14 governorates Sunday and Monday.
The second stage of the parliamentary elections, when voters from the remaining 13 governorates will cast their ballots, will take place from 21-22 November abroad, and 22-23 November domestically.
Egypt’s parliament — the House of Representatives — will comprise 596 members, 448 elected as independents and 120 from party-based lists. The remaining 28 seats will be filled by presidential appointees.
The country has been without a parliament since the previous legislature, elected in late 2011, was dissolved in June 2012 after a court ruled electoral laws in place to be unconstitutional.
President Abdel-Fattah El-Sisi currently holds legislative powers.
Once a parliament is elected, its members will have to vote on all laws issued by El-Sisi and his predecessor, Interim President Adly Mansour.
