The FIA confirmed the WRC would follow Formula 1’s lead and allow drivers to carry permanent numbers at the October meeting of the World Motor Sport Council.
Priority 1 drivers revealed their numbers in Birmingham.
The only full-time driver not participating was Sebastien Ogier, who retains the number one reserved for the World Rally champion.
Ogier's Citroen teammate Esapekka Lappi will carry #4 in his first season with the French manufacturer, while Hyundai's lead driver Thierry Neuville will compete with the #11.
Fellow Hyundai driver Andreas Mikkelsen has selected #89 - the year of his and co-driver Anders Jaeger's birth - while Kris Meeke will run with #5 when he returns to the championship with Toyota, having allowed his daughter to choose his number.
Sebastien Loeb, who will contest a part-time campaign with Hyundai in 2019 but is currently competing at the Dakar Rally, did not have a number assigned to him at the unveiling, but subsequently revealed he will use #19.
