Saudi Arabia severed relations with Iran in 2016 after its embassy in Tehran and consulate in the northwestern city of Mashhad were attacked during protests over Riyadh's execution of Shia cleric Nimr al-Nimr.
Iran's diplomatic mission, which was expelled by Saudi authorities, will return under the leadership of Alireza Enayati, who previously served as Iran's ambassador to Kuwait.
Tehran's foreign ministry spokesman Nasser Kanani announced the reopening in a statement Monday, confirming earlier comments by a diplomatic source in Riyadh.
Iran's embassy in Riyadh, its consulate in Jeddah and its representative office to the Organisation of Islamic Cooperation (OIC) "will be officially reopened on Tuesday and Wednesday", Kanani said.
The diplomatic source had earlier told AFP that the opening "will take place Tuesday at 6:00 pm local time (1500 GMT) with the presence of the newly appointed Iranian ambassador" to Saudi Arabia.
Saudi Arabia has yet to confirm when it will reopen its embassy in Tehran or its pick for ambassador.
Iranian media had named Enayati as the Islamic republic's Saudi envoy last month.
He had previously served as assistant to the foreign minister and director general of Gulf affairs at the foreign ministry, according to Iranian reports.
After years of discord, the two Middle East heavyweights signed a surprise reconciliation agreement in China on March 10.
Since then, Saudi Arabia has restored ties with Tehran ally Syria and ramped up a push for peace in Yemen, where it has for years led a military coalition against the Iran-backed Huthi rebels.
Iran and Saudi Arabia had backed opposing sides in conflict zones across the Middle East for years before mending fences.
