On the Inca Trail, your passport does more than just allow you to enter Peru. Its details are used to register your permit. If the name or number does not match the document you present at the checkpoint, entry can become complicated. Here is the validity required by Immigration, what to do if you renew it after booking, and the most common mistakes when submitting your details.
Why your passport is so important on this route
The permit is personal. The space is linked to your identity and cannot be used by someone else.
When booking, the agency asks for your first and last names exactly as they appear on the document, passport or DNI number, nationality, and date of birth. At the trail entrance, they compare this information with the original document. They must match.
How much validity your passport needs to travel to Peru
If you enter Peru with a passport, Immigration requires at least six months of validity from the day you enter the country. This is not a trekking rule: it is an entry requirement. With less time, you may have problems when boarding or upon arrival.
If you enter on June 10, your passport should be valid at least until December 10. Check the expiration date before buying flights or booking the Inca Trail, and also review visa and layover requirements based on your nationality.
Travelers entering with a DNI from the Andean Community or Mercosur must book and show the same type of document that was registered.
What to do if your passport expires close to your travel date
If it does not have those six months from your arrival in Peru, renew it before booking. That way, the permit will be issued with the new number and the details will not need to be corrected later. Do not leave it until the airport or the trail entrance.
What to do if you change your passport after booking
If you renewed it, lost it, or were issued a new one, notify the agency that processed your permit on the same day. They will ask for a copy of your previous passport, a copy of the new one, your booking code, and the hike start date.
The agency will check whether the number can be updated. The change applies to the document, not the person: it cannot be used to transfer the permit to another traveler. At Machu Picchu, it may sometimes be possible to correct the number for the same permit holder; changing the name is not as straightforward. Do not assume the system updates automatically.
Should you bring both your old and new passports?
If you booked with the old number, bring your valid new passport, the old one if you still have it, the email in which the agency confirms the correction, and a photo of both just in case.
Bringing both helps identify you as the same person. It does not replace notifying the agency. Showing up with only a document different from the one registered, without prior notice, may delay you at the checkpoint.
Common mistakes when registering your passport
Writing your name differently
Copy it exactly as printed: compound surnames, middle name, order, and every letter. No nicknames or shortened versions.
Getting the passport number wrong
Similar-looking characters are easy to confuse. Even one mistake means it will not match the document at the checkpoint:
- The letter O and the number 0
- The letter I and the number 1
- The letter B and the number 8
- The letter S and the number 5
- The letter Z and the number 2
Copy it from your passport, not from memory, and check the number in the confirmation before considering it correct.
Booking with a passport that will soon be renewed
If you already know you will renew it, say so before paying. The agency will tell you whether to wait for the new number or register the current one.
Sending a blurry photo
The copy must be fully visible: photo, name, number, nationality, date of birth, and expiration date.
Not checking the booking confirmation
The day you receive it, compare it with your passport. Correcting it now is easy; at the trail entrance, it is not.
How to avoid passport problems
Before booking, make sure your passport has six months of validity from your entry into Peru and use the document you will travel with. Send a clear copy, check your name and number in the confirmation, and notify the agency as soon as there is a renewal, loss, or change. Bring the original on the hike. This applies equally to the 4-day Classic Inca Trail and the 2-day Short Inca Trail.
Frequently asked questions
How much validity does my passport need?
Six months from the day you enter Peru. If it does not have that validity, renew it before your trip.
Are the six months counted from the booking date or from the hike?
From the day you enter Peru, not from when you book or from the first day of the trek.
What should I do if I renew my passport after booking?
Notify the agency and send copies of the old and new passports so they can update the number.
Can I enter with a passport different from the one used for the booking?
The registration must be updated first. Bringing both documents helps, but it is not enough if no one corrected the details.
Can I transfer my permit to another person?
No. Only the number for the same permit holder can be corrected.
What happens if there is a mistake in my name?
Report it as soon as you see it. Changing the name is more difficult than changing the number.
Do I need to bring the physical passport?
Yes. A photo of the document does not replace the original at the checkpoint.
Does my passport need to remain valid for six months after finishing the hike?
Immigration calculates this from your entry into the country. It is advisable for it to remain valid until you leave Peru.
