For future improvement we might want to look at some leniency for whitespaces in between the 'segments' (so something like FR 12 345678912 might be valid as well) but on a quick search I didn't find good resources for that. For now this is already an improvement.

I do also see all resources pointing towards requiring FR at the start, so that's also a change I'm approving

Thanks for the review! I agree — adding leniency for whitespaces could be a useful future improvement. For now, I’ll leave it strict since that’s what most resources confirm.

For "whitespaces", we could remove all of them from the string before validating it with the regex.
Should we add a strict option to handle tests with or without trimming whitespaces?
What characters should be considered as whitespaces? For example, blank spaces, non-breaking spaces, tabs, etc.?

Currently, validation without whitespaces seems to me more reliable than a version that allows them.
