When we buy your ticket, we give the authorities your information, including the number of your identity document, which is:

• For Peruvians: the number of the national identity document (DNI).
• For Residents in Peru: the number of the allien card (CE)
• For border countries having a circulation agreement with Peru: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Uruguay, the number of the national identity card or the passport number.
• For everybody else, that is for most of the people: the number of their passport. No other document is accepted.

You can only purchase if the document is valid. You cannot purchase if the document is not valid, if it is temporary or if it will be expired on the date of the visit. If your document is being issued or renewed, you must wait to have the final document to purchase.
