How the Compostela Works: The Rules for Earning Your Camino Certificate

Updated June 2026

Short answer: the Compostela is the certificate the Cathedral of Santiago issues to pilgrims who complete the Way. To earn it on foot you must walk at least the last 100 km into Santiago along a recognised route — on the Camino Português that means starting at Tui (or earlier) — and prove it with a stamped credencial (pilgrim passport), collecting two stamps a day over that final 100 km. You claim it in person at the Pilgrim's Office in Santiago, where you're asked your reason for walking. The certificate itself is free. That's the whole system — the rest is detail worth knowing before you go.

Almost everyone who walks the Camino Português is walking, at least in part, toward one thing: standing in the Pilgrim's Office in Santiago with a stamped passport, receiving a hand-inscribed certificate with your name on it in Latin. It's the oldest souvenir in Europe. But the rules around it — how far, how many stamps, what to carry, what you'll be asked — are strangely hard to pin down, and getting a detail wrong (the wrong start point, too few stamps) is one of the few Camino mistakes you genuinely can't fix afterwards. Here's exactly how it works, checked against the official Pilgrim's Office in Santiago.

What is the Compostela, exactly?

The Compostela is the traditional certificate of pilgrimage, issued by the Cathedral of Santiago de Compostela to those who reach the tomb of St James. It's written in Latin, it carries your name in Latinised form, and the practice of accrediting the pilgrimage this way goes back centuries — today's certificate is the direct descendant of the "evidentiary letters" pilgrims were given in the 13th century. It is not a completion medal you buy; it's a document the Church grants on specific conditions, and it is issued free of charge. Think of it less as a receipt for kilometres walked and more as formal recognition that you made the pilgrimage — which is why, as you'll see, your reason for walking is part of the deal.

How far do you have to walk to earn it?

The rule is simple and non-negotiable: on foot, at least the last 100 continuous kilometres into Santiago, along one of the officially recognised routes, and your final day must be the stage that ends at the cathedral. On the Camino Português, the natural place to start for exactly 100 km is Tui, on the Spanish side of the border with Portugal — from there it's roughly 115 km, comfortably clearing the minimum with a little margin. Walk from Porto and you cover around 240–260 km, far more than needed; the 100 km rule only matters if you're doing a shorter Camino.

Two variations are worth knowing. If you travel by bicycle, the minimum doubles to 200 km — so cyclists on the Portuguese Way typically start from Porto. And if you began walking outside Spain (for instance, from Porto or Lisbon), the distance required inside Spain drops to 70 km, because you clearly started your journey much earlier. For the overwhelming majority of Português walkers, though, the headline is the one to remember: get yourself to Tui or further back, and you're covered.

What is the credencial (pilgrim passport)?

The credencial — the pilgrim passport — is the small folded card you carry the whole way and get stamped as you go. It's the single most important thing in your pack after your feet, because no credencial means no Compostela: it's the only accepted proof that you actually walked the route. The official version is a sturdy card that folds out concertina-style into sixteen pages, most of them blank boxes waiting for stamps. You fill in your name and details on the front, and the Pilgrim's Office adds the final cathedral stamp when you arrive.

You can pick one up before you leave — Confraternities and Associations of the Camino in many countries distribute them — or on the route itself. In Porto there's a Pilgrim's Office that issues them, and you'll also find them at some cathedrals, parish churches, and a good number of albergues along the way. There's now an official digital credential app too (Android and iOS), where stamping points can add a digital stamp — handy, though many walkers still prefer the paper card as a keepsake. One point that trips people up: for the Compostela to be granted, the credencial has to have been issued by a Church-related body (a parish, confraternity, association or the office itself), so pick up an official one rather than an unofficial souvenir version.

How many stamps do you need — and where do you get them?

A stamp is called a sello, and collecting them is the small daily ritual of the Camino. The rule that matters: over the final 100 km, you need at least two stamps per day, each dated. Before that last stretch, one a day is enough. The two-a-day rule exists to prove you walked the whole way continuously rather than skipping ahead by bus or taxi, so the dates need to line up in order.

Getting them is easy and rather fun. Albergues and hostels stamp your credencial when you check in; so do many cafés and bars along the route, churches, monasteries, town halls, and tourist offices — anywhere with a Camino connection tends to have a stamp, and each one is different, so your passport slowly fills with a collage of the places you passed. A practical habit that saves anxiety on the last stretch: get one stamp where you sleep and a second somewhere you stop for coffee or lunch, and you'll never arrive in Santiago a stamp short. If you're walking the minimum distance in stages rather than in one go, get a stamp at both the start and the end of each stage — including re-stamping at the exact point you restart — so the trail of dates is unbroken.

Do you have to be religious to receive it?

This is the question that worries a lot of non-religious walkers, and the honest answer is reassuring. The Compostela is, formally, a religious certificate — the Cathedral grants it to those who walk "with Christian sentiment." But in practice the office reads that generously: it explicitly counts a spiritual or personal search as qualifying, so the great majority of walkers, religious or not, receive the Compostela. When you register in Santiago you'll be asked, gently, what your motivation was — religious, spiritual, or otherwise. If your reasons were genuinely spiritual or a personal journey, you get the Compostela. If you say your walk was purely non-religious — sport, culture, a holiday — the office issues a different welcome certificate instead, which records your achievement without the religious wording. Either way you're recognised; just answer honestly, and don't overthink it.

Where and how do you collect it in Santiago?

You claim the Compostela in person at the Pilgrim's Reception Office (Oficina de Acogida al Peregrino) on Rúa das Carretas, a short walk from the cathedral. You present your stamped credencial, register your details, and — assuming your stamps and distance check out — the certificate is inscribed with your name and handed over. The office is open every day from 9am to 7pm (closed only on 25 December and 1 January).

The one thing to be ready for is the queue. In busy months the line can be long, and the office uses a QR-code ticket system so you can see your place in real time rather than standing in it. In peak season they warn that same-day collection isn't always guaranteed, so if you arrive late in the afternoon at the height of summer, you may be picking it up the next morning. Plan to reach Santiago with a little time in hand rather than racing for a same-day flight home — you'll want a spare afternoon for the cathedral and the Pilgrim's Mass anyway.

Is the Compostela the same as the "certificate of distance"?

No — and it's worth knowing the difference, because the office offers both. The Compostela is the traditional Latin certificate described above, and it's free. The certificate of distance (certificado de distancia) is a separate, optional document that records the specifics of your walk: your exact starting point, the route you took, your start and finish dates, and the total kilometres covered. It's printed on parchment, slightly larger than the Compostela, and carries a small fee — around €3 at the office — which helps fund the free pilgrim service. Many walkers buy it as a more personal keepsake to frame alongside the Compostela, precisely because it names the distance and the journey you made. It's entirely a nice-to-have, not a requirement.

Our honest take

Don't let the certificate become the whole point — but don't sabotage it on a technicality either. The two things that actually catch people out are the start point (make sure you're beginning at or before Tui if you're walking the minimum) and the two-stamps-a-day rule over the last 100 km (build the habit early so it's automatic). Get those right and the Compostela takes care of itself. And when you do stand in that office with a passport full of mismatched stamps, the certificate matters far less than the wall of them — every café, every albergue, every dated smudge is a day you can point to. That's the real record. The Compostela just makes it official.

Next steps: now you know the rules, plan the walk that earns it. Map your days with the Camino Português planner, see exactly where Tui and Santiago fall in the stage-by-stage guide, and sort the practical bits — insurance, an eSIM, transfers — with what to book before you go.
