Two numbers decide whether your US passport is ready for Cambodia: six months of validity from your arrival date, and one full blank page. Get either wrong and the airline stops you in the United States, before you ever reach Phnom Penh.

Your US passport must be valid for at least 6 months from your date of entry into Cambodia and must have at least one full blank page for the entry stamp. Validity is counted from the day you arrive, not the day you apply for the eVisa, and the 6-month rule is enforced by the airline at your US departure gate. The eVisa is tied to the exact passport number on your application, so if your passport is expiring soon or short on pages, renew it first and then apply on the new book. Damaged passports and recently changed names are the two edge cases that catch Americans out most often.
This guide covers exactly how the 6-month window is counted, how many blank pages you really need, what happens if your passport is damaged or recently renamed, and how renewal timing fits around your eVisa. For the bigger picture on whether you need a visa at all, start with our overview of whether US citizens need a visa for Cambodia, then come back here for the passport specifics. The full Cambodia visa for United States citizens hub ties the cost, documents, and timing together in one place.
If your passport is sitting right on the edge of the window, do not gamble on a sympathetic gate agent — there is no discretion built into the system. Renew first. We break the timing down in detail in our guide to the US passport 6-month rule for Cambodia, and the broader Cambodia visa requirements for US citizens checklist shows how the passport rule sits alongside the other entry conditions.

A quick reality check on the standard US passport: the regular book has 28 pages, of which around 17 are usable visa pages once you set aside the cover, signature, and endorsement pages. The 52-page book — what the State Department now issues by default in many cases, and which you can request at no extra cost — gives you far more runway. If you travel often and you are renewing anyway, opt for the larger book and you will not think about pages again for years. To see how the blank-page rule sits alongside everything else you need, the Cambodia visa requirements for US citizens checklist walks through exactly what counts as a clean page.

The unifying rule behind both edge cases: your eVisa is tied to the exact passport number you enter on the application. If you renew after applying — even for the same person, same name — the old eVisa is attached to a passport you are no longer carrying, and that mismatch can stop you at the gate. So renew first, then apply on the new passport number. The same principle drives every item on our Cambodia eVisa documents checklist for Americans, where the passport scan has to match the data you type.
