Can You Smile in a Passport Photo?
As seen on:

Before getting to the heart of the matter, we would like to say something about facial recognition and biometric passport photos.

The main point of biometric photography is to facilitate facial recognition. This kind of software compares the data from your passport photo with a scan of your facial features at the airport based on precise measurements of your appearance.

Smiling can make it harder for facial recognition software and port officials to confirm your identity, especially if you show your teeth. Only the United States currently allows smiles on passport photos; however, the subject’s teeth can only be slightly visible.

Thus, only a natural smile is acceptable, silly faces, forced smiles, and wide-mouthed grins are all off the table.

Biometric passport photos and facial recognition

For humans, facial recognition is an automatic, unconscious process. However, software needs to examine all features separately, making it a much more complex action. Machines need to compare a 2-D image with a 3-D face. They can only do it by analyzing features from an image.

For this reason, high precision equipment in airports, metro, and train stations (like in Osaka, Japan), hospitals, and many other high-traffic areas take detailed measurements of people’s facial features—width of the eyes and the mouth, the distance between them, etc.

To make this whole process easier, ICAO (International Civil Aviation Organization) imposes specific rules on biometric passports. Today, all passports are biometric and they contain a chip storing all the information the software needs. This is why the ICAO requirements are now the standard for issuing passports.

Smiling in passport photos—children

As you now know, except for the U.S., most countries require adults to have a neutral expression on their passport photos. What about children, though?

Because it’s not generally easy to convince children, babies, in particular, to maintain a neutral expression, they are allowed to smile. It can’t be an exaggerated smile that distorts the features, but, usually, it’s enough for children to keep their eyes open and face the camera for the passport photo to be accepted.

It would, of course, be better if your baby didn’t smile, but government officials do understand that it’s not possible to convince very young children to keep a straight face, so they are quite tolerant.

Smiling in passport photos in different countries

Not all countries define a “natural smile” in the same way. While most official requirements around the world allow subjects to display  barely a hint of a smile, some countries have no leniency on the matter. For instance, the French Government forbids  even the slightest hint of a smile in passport photos.

The U.K., Canada, and Australia require applicants to maintain a completely neutral expression since their facial recognition software might have problems identifying a smiling face.

In any case, a neutral expression is the preference of most countries around the world. To avoid any issues abroad, even in the United States, applicants are advised to avoid smiles in passport photos.

Passport photos will stay with us for 10 (ten) years and we have to show them to customs officials, flight attendants, and many more people. So, wanting to look the best we can is perfectly understandable.
