Here's my experience from 2013 ...
In Irun I met two guys, Jack and Joe, from South Wales. Together we found the Albergue de Peregrinos only to discover it does not open until 4PM. ("We have to clean up sometime.") Now, this is how the Camino works. Jack and Joe say they need to get a pilgrim passport because they are leaving Irun before 4PM. There is a sign on the Albergue door in five languages that says one can get passports until 12:30 PM at the Passionistas Church on Estación street. Jack says, "I think we were just at that church, but it was called San Gabriel. And, it's closed." I say,"Lets try again, maybe there is a side door." So we return to the Church, which apparently goes by both names, although "it's really not a church," according to one local. Both the main door and side door are closed. Just then I see a priest getting into a car and ask him when the church is open. He sees that we are pilgrims and explains that we have to ring a bell on a side building. We do. Five minutes later another priest opens the side building door, issues passports to Jack and Joe, and stamps my American issued pilgrim passport, which is no way as pretty as the Spanish one.
