Only registrations with letters (SE-AAA - SE-ZZZ) can generate IACO 24-bit addresses with this algorithm. Registrations containing digits are assigned manually. Also, addresses assigned before 1MAR2003 should continue to be used. See Transportstyrelsens Författningar för luftfart LFS OPS 2007:31 Elektronisk adress för flygburen utrustning for details.
