在不同的护照上返回柬埔寨：2026年澳大利亚人指南
更换了澳大利亚护照？结婚后使用新姓氏？持第二本护照出差？柬埔寨将每一个新护照号码视为新的申请人——以下是哪些会改变，哪些保持不变，以及生物识别仍然会捕捉到什么。
I'm an Aussie returning to Cambodia on a different passport — what do I need to know about the eVisa?
Each Cambodia eVisa application is keyed to the passport number, not your underlying identity. A renewed Australian passport, a second passport for business travel, or a passport in a new married surname produces a fresh application with no carry-over from prior trips — same $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business fee, approved in 3 business days, delivered as a printable PDF by email. Cambodia's MFAIC has no visibility on your prior visa history under the old passport number, so you apply as a 'new' applicant. The one place identity does resurface is at Immigration biometrics on entry — face match and fingerprint can still tie you back to a prior Cambodia record, which only matters if your earlier history included an overstay, deportation, or fraud flag.
要点总结
- Cambodian Immigration keys to passport number, not person identity. A renewed, replaced, or post-name-change passport produces a fresh eVisa record with no link to prior trips on the previous passport number.
- Your prior visa history isn't visible to MFAIC under the new passport — you apply as a 'new' applicant with $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business, approved in 3 business days.
- Name-change marriage, DFAT renewal, second passport for business, and emergency replacement all produce the same application shape — what differs is the supporting paperwork you may need to carry on the plane.
- Biometrics on entry (face match, fingerprint) can still surface a prior Cambodia record even when the passport number is new — relevant only if your earlier history included an overstay, deportation, or fraud flag.
- The fix for a passport number mismatch on an existing eVisa is a free resubmission with the new details — never travel on a PDF that shows the old number.
Why Cambodia treats a new passport as a new applicant
If you want the wider context of how the eVisa history record actually works for Australian applicants, the Cambodia eVisa history record guide for Australian applicants covers what MFAIC stores and what travel agents see. The Cambodia eVisa passport renewal DFAT guide for Australians walks through the specific case of mid-validity renewal and what to do with the old passport's stamps. The official Cambodia eVisa for Australians hub covers cost, documents, and processing time in one canonical write-up.
The four Aussie scenarios — different passport, different paperwork
DFAT issues second Australian passports for travellers whose work requires overlapping visas — consultants, NGO staff, journalists, sales staff with concurrent visa applications in multiple countries. A second passport carries its own unique number and a five-year validity. The eVisa application is keyed to that second-passport number; Cambodia treats it as a wholly separate document. Carry the DFAT authorisation letter that links the two passports — airlines sometimes flag the second-passport boarding pass if the system has the primary passport on file. The Cambodia eVisa second passport guide for Australians has the full mechanics.
Lost-passport scenarios in transit, or inside Cambodia, produce a DFAT emergency travel document or a short-validity emergency passport. The eVisa application on the emergency document uses the document number printed on it. Cambodian Immigration will accept the application as long as the document is genuinely a current Australian travel document; bring the DFAT emergency letter and, if relevant, the police report of the lost passport. The Cambodia eVisa emergency passport DFAT guide for Australians covers the in-Cambodia replacement flow specifically.
What the fresh application actually looks like under a new passport
常见问题解答
I just renewed my Australian passport — does my old Cambodia visa history carry over?
No. Cambodia keys every eVisa record to the passport number, so your renewed passport produces a fresh applicant record with no link to prior trips on the old number. Apply on the new passport — $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business, approved in 3 business days, delivered as a printable PDF by email. The cancelled stamps on the old passport are not operationally relevant at KTI, SAI, or KOS.
Do I need to mention previous Cambodia visits when applying on a new passport?
No. The eVisa form has no field for prior Cambodia history under a different passport number and does not require you to declare it. Type the new passport details exactly as they appear in the machine-readable zone, apply, and treat the application as you would a first-time application. Cambodian MFAIC has no system view of the prior record under the old number.
I got married and my passport is in a new surname — what does the eVisa application look like?
A fresh application on the new passport, using the name exactly as it appears on the new passport's machine-readable zone. Same $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business fee, 3 business days, printable PDF by email. Carry the marriage certificate and a statutory declaration of name change in your carry-on for airline check-in scenarios where booking details still reference the maiden name.
I travel on a second Australian passport for business — does Cambodia accept it?
Yes. DFAT-issued second passports are valid Australian travel documents and Cambodia processes them like any other Australian passport. The eVisa is keyed to the second-passport number; carry the DFAT authorisation letter that links the two passports in case an airline flags the second-passport boarding pass. The Cambodia eVisa second passport guide for Australians has the full mechanics.
Can my biometrics still tie my new passport back to my old Cambodia visits?
Yes — Cambodian Immigration runs face-match and fingerprint biometrics on air arrivals at KTI, SAI, and KOS. The system can link your new-passport entry back to a prior visit on the old passport. For travellers with clean prior history, this surfaces nothing the officer cares about. For travellers with a prior unpaid overstay, deportation, or fraud flag, the biometric link is the moment Immigration brings it up — clear the prior issue before returning.
What if my old passport had an unpaid Cambodia overstay — does a new passport reset it?
