Pakistan Army said the Indian devotees using the Kartarpur corridor will need to produce a passport.
Pakistan Army spokesman Maj Gen Asif Ghafoor comments in Pakistani media come a day after India asked Islamabad to clarify its stand whether passport will be required by Sikh pilgrims visiting the Gurdwara in Kartarpur.
Earlier on November 2, Pakistan's Prime Minister Imran Khan announced that Indian Sikh pilgrims would only require a valid ID to visit the Gurdwara Darbar Sahib.
The kartarpur corridor, scheduled to be opened on November 9, links the Gurdwara Darbar Sahib in Pakistan - the final resting place of Guru Nanak Dev-with Dera Baba Nanak in Gurdaspur.
On November 1, Prime Minister Khan said he had waived two requirements relating to passport and registering 10 days in advance for Sikhs coming for a pilgrimage to Kartarpur from India.
This year marks the 550 birth anniversary year of Sikhism founder Guru Nanak Dev on November 12, whose birthplace is Sri Nankana Sahib in Pakistan. The corridor has been established to commemorate his birth anniversary.
