Licence plate recognition: our measured results.

Here we publish, country by country, what IA-N's licence plate recognition reads correctly and what it reads incorrectly, on real photos. The good figures and the bad ones.

Last updated: 31 October 2026

In brief Two countries currently have published results: France (“measured” status) and the Netherlands (“on trial” status). Five others are being measured. Anything that has not been measured is marked “not measured”: we estimate nothing.

Method

How we measure.

Real photos. The test set is made up of real photos of vehicles, taken in conditions of use, not of fabricated or retouched images.
A reading checked by eye. For each photo, a person reads the plate themselves and compares it with the software's reading.
If in doubt, it is discarded. If the plate remains hard for a person to read, the photo is removed from the test: we do not rule in place of the human eye.
A version and a date. Each result states the software version tested and the date of the measurement. A result is valid only for that version.

Definitions

“Correct” and “incorrect”.

Term	What it means
Correct	The software read the whole plate and the reading is identical to the actual plate.
Incorrect	The software gave a reading, but it differs from the actual plate (one character confused, added or missing is enough).
Neither correct nor incorrect	The software gave no reading for this plate.

Transparency

Why we also publish the bad figures.

An installer or a customer choosing licence plate recognition needs to know what to expect from it, including what does not work yet. An incorrect read can trigger a wrong alert or open the wrong file: the “incorrect” rate matters as much as the “correct” rate. We prefer an honest, modest figure to a promise that nobody can verify.

Good to know

What these figures do not tell you.

These results come from a specific, dated test set and a specific version of the software. On your site, the result depends on the camera, its settings, the light and the location. To find out what it will give at your site, see the Licence plate recognition (ANPR) page or ask us the question.
