Why a neutral expression?
Passport photos feed facial-recognition systems that compare your face at the border. Those systems are calibrated to a neutral, relaxed face — which is why a big smile, raised eyebrows, or an open mouth distorts the match and gets the photo rejected.
What’s allowed vs. rejected
- Allowed: a relaxed, neutral face, mouth closed, both eyes open and looking at the camera.
- Allowed in some countries (incl. the US): a slight, natural, closed-mouth smile.
- Rejected: an open mouth, teeth-showing smile, raised eyebrows, frowning, or squinting.
- Safest everywhere: keep it neutral with your mouth closed.
We catch an open mouth before you submit
Our checker measures your expression and flags an open mouth automatically, so a too-big smile doesn’t cost you a rejection. If it’s flagged, just retake — checking is free.
Frequently asked
Can you smile in a US passport photo?
A slight, natural, closed-mouth smile is tolerated, but a neutral expression is recommended and always safe. A teeth-showing smile or an open mouth will be rejected.
Can you smile in a UK or European passport photo?
No — these require a neutral expression with your mouth closed and a relaxed face. Don’t smile.
Do babies need a neutral expression?
No. The neutral-expression rule is relaxed for infants — a baby doesn’t need to pose. Eyes open is preferred where possible, but not always required for newborns.
Will a small smile get my photo rejected?
A slight, closed-mouth smile is usually fine in countries that allow it, but an open mouth or visible teeth is rejected. Our check flags an open mouth so you can retake.
