Pilgrims travelling along the Way of St. James for religious or spiritual reasons, and who therefore want to obtain the so-called ‘Compostela' certificate at the end, as well as those wishing to use the network of hostels, need to leave home with pilgrim credentials. These consist of a booklet issued by the diocese of origin’s Pilgrimages Delegation, by the parish or by the local Association of Friends of the Way of St. James, which is stamped for pilgrims by the hostels along the route to certify the stages they have completed on foot, on horseback or cycling.
As of 2009, the Compostela certificate can only be obtained by means of the official Pilgrim Credential model issued by the Church through its institutions: Diocese, Parish, St. James Brotherhood and other authorised distributors.
