 <b>Note:</b> Under the SIV system, registration plates contain seven alphanumeric characters: two letters, a dash, three numbers, a dash and two letters, such as AA-229-AA. The system is nationwide and chronological. The first car registered in France under the SIV received a AA-001-AA registration plate, the second one AA-002-AA, the third AA-003-AA. The system will be exhausted when ZZ-999-ZZ is reached, which is scheduled to occur after 80 years of use.
