French vehicle registration in the SIV format used since 2009, two letters, three digits, two letters, separated by hyphens. The letter class drops I, O and U, which the SIV never issues, and the lookarounds stop a longer hyphenated token from matching a fragment. Noise is very low, the mask is distinctive. Plates issued before 2009 under the FNI are not covered, nor are the W garage and WW temporary series. A registration is personal data in France, because it resolves to a keeper through the SIV. No collision with any existing pattern.
