New ISO/IEC 39794-5 biometric photo standard for passports: rollout begins in 2026
In short. From January 1, 2026, border systems must recognize the new ISO/IEC 39794-5 biometric photo standard; full rollout completes by 2030.
- From January 1, 2026, all border control systems must be able to read the new ISO/IEC 39794-5 biometric photo encoding standard.
- Full mandatory adoption across all 193 ICAO member states is due by January 1, 2030.
- The standard doesn't directly change physical photo requirements like size or background — those remain set by each country.
- A growing number of countries, including the USA, now formally ban AI-edited and filtered photos because they affect biometric matching accuracy.
- The safest option is a recent, unedited photo with no filters and no AI processing.
Starting January 1, 2026, border control systems worldwide must be able to read passport photos encoded under the new international biometric standard ISO/IEC 39794-5 — a requirement set out in technical reports from the International Civil Aviation Organization (ICAO), which governs electronic passport (eMRTD) rules across its 193 member states.
What ISO/IEC 39794-5 actually is
ISO/IEC 39794-5 is a new format for encoding the facial biometric image stored on an electronic passport's chip. It gradually replaces ISO/IEC 19794-5:2005, which had been in use for more than fifteen years. The new format stores more than just the photo itself: precise facial landmark coordinates, image quality scores, information about the capture device, and data used for presentation attack detection (spotting attempts to fake or substitute an identity). The format is extensible, meaning new types of biometric data can be added later without a full overhaul of border-crossing equipment.
Transition timeline
| Date | What happens |
|---|---|
| January 1, 2026 | Passports may start using the new ISO/IEC 39794-5 format; all border inspection systems must be able to read it |
| 2026–2030 | Transition period: passport-issuing states may use either the old format (ISO/IEC 19794-5) or the new one |
| January 1, 2030 | All newly issued electronic passports must encode facial photos exclusively in ISO/IEC 39794-5 |
Why ICAO is changing the format
The 2005 standard was designed when automated face recognition at borders was still new. It stored minimal data and poorly supported newer capabilities, such as comparing multiple images of the same face or scoring image quality directly on the chip. The new format addresses those limits and lays the groundwork for border systems in different countries to recognize the same face with consistent accuracy, regardless of where or on what equipment the original photo was captured. According to ICAO, the additional data adds only a small amount to chip storage, so the transition mainly involves updating reader software rather than replacing passport booklets or chips.
Who this affects
The transition covers all 193 ICAO member states — effectively nearly every passport and border-control system in the world. Existing passports remain valid until they expire; nobody needs to replace a current document because of this change. But anyone applying for a new passport, visa, or residence permit after 2026 will run into progressively stricter automated photo checks, both at consulates and at the border.
What it means for an ordinary applicant
The standard itself does not change photo requirements such as size, background, or pose — those remain set by each country's own rules. What changes is how precisely the border system can match a live face against the image stored on the chip. In practice, that means low-quality photos, uneven lighting, or an expression that doesn't meet the rules are more likely to get flagged by automated checks than they would have been on older equipment.
AI-edited photos are drawing separate scrutiny
Alongside the technical transition, a growing number of countries are formally banning photos edited with artificial intelligence or skin-smoothing filters. The clearest example is the United States: as of 2026, official guidance on travel.state.gov explicitly instructs applicants not to alter their photo using software, apps, filters, or AI tools, citing the effect such editing has on biometric matching accuracy. Similar warnings are appearing more often in other countries' consular requirements. It's part of the same underlying shift as the move to ISO/IEC 39794-5: the more precise biometric checks become, the more visible even small edits are to the algorithm — edits that used to pass unnoticed.
What to do now
If you have a passport or visa application pending, or plan to submit one soon, use a recent, unedited photo taken with a plain camera — no "portrait mode," no skin-smoothing filters. Always check the exact requirements of the specific country or consulate you're applying to; they don't change automatically because of the new encoding standard, but quality checks at borders and consulates are already getting stricter. If you're preparing a photo in advance, keep the original free of any post-processing — that way it's easier to adjust it later for specific requirements instead of reshooting from scratch.

Questions
- Do I need to replace my current passport because of the new ISO/IEC 39794-5 standard?
- No. The transition concerns how a face photo is encoded on the chip of new passports, not the validity of documents already issued. A current passport remains valid until it expires; replacement is only needed for the usual reasons — expiry, a change of personal details, or a damaged document.
- Will passport photo size and background requirements change because of this standard?
- The physical parameters of the photo — size, background color, head position — are set by each country's own rules, and ISO/IEC 39794-5 does not directly define them. What changes is how the system encodes and compares the facial image, not how the photo should look on paper.
- Why are photos with filters or AI editing suddenly being rejected more often?
- More precise encoding standards and automated checks at borders and consulates are better at catching any difference between a live face and the stored image. Even light skin smoothing or facial retouching changes the model the system reads, so such photos more often trigger a second look or an outright rejection.
- What should I do if I need to submit documents right now, during the 2026–2030 transition period?
- Do exactly what you would have done before: submit a photo that meets the official requirements of the specific country or consulate, with no digital editing. The transition period means both encoding formats are accepted, so no extra action is required from applicants — just avoid AI tools or filters when preparing the photo.
