Merkheperre appears on the Turin canon, a king list compiled in the early Ramesside period.

The Turin papyrus is damaged on the section covering the late 13th Dynasty and Merkheperre's reign length is lost in a lacuna.

Merkheperre is also attested by two artefacts dating to his reign: a glazed weight of grey schist bearing his cartouche, now in the Petrie Museum UC 16372[5][6] and a scarab inscribed with his name.

Although the scarab is accepted as evidence of Merkheperre by Darrell Baker, Jürgen von Beckerath, Stephen Quirke and others, Kim Ryholt rejects this attribution.

[2] The exact chronological position of Merkheperre is not known for certain as the damaged state of the Turin canon only allows for conjectural reconstructions of the late 13th dynasty.
