The ceremony will take place at the cathedral in his home town of Modena, northern Italy.
U2 frontman Bono and former United Nations secretary general Kofi Annan are expected to attend, alongside Italian prime minister Romano Prodi.
Singers Placido Domingo and Jose Carreras - who, with Pavarotti, formed the Three Tenors - are also on the guest list.
Among the family members will be Pavarotti's widow, Nicoletta Mantovani.
The Frecce Tricolori, Italy's equivalent of the Red Arrows, will perform a flypast.
Andrea Bocelli will sing Panis Angelicus, a piece often performed by Pavarotti.
Thousands of mourners will pack the cobbled square outside to see the service relayed on a giant screen. Other screens have been erected around the town and the ceremony will also be broadcast live on Italian television.
The 71-year-old singer died on Thursday morning after losing his battle with pancreatic cancer.
The tenor will be buried in the Montale Rangone cemetery on the outskirts of Modena.
