Vehicle registration plates of Singapore

Private vehicle numbers started in the mid-1900s when Singapore was one of the four Straits Settlements, with a solitary prefix S for signifying Singapore, then, at that point, adding a suffix letter S ‘B’ to S ‘Y’ for vehicles, however avoiding a couple of like S ‘A’ (held for bikes), S ‘H’ and S ‘Z’ (saved for taxicabs and transports), S ‘D’ (saved for municipal vehicles), and S ‘G’ for small and large vehicles. There was no checksum letter, for instance, S. At the point when the checksum letter was executed, these plate numbers were given checksum letters too, for instance, SG5999 became SG5999Z.

At the point when ‘S’ was depleted at SY, in January 1972, private vehicles began with E and Land Transport Authority started to make separate vehicle classes concurring kind of vehicles which already all vehicles in Singapore should bear prefix S because of past normalization with Peninsular Malaysia as indicated by topographical area (An is for Perak, B is for Selangor, S is intended for Singapore/Sabah), motorbikes with An and merchandise vehicles under 3 tons with Y. E was trailed by EA, EB with the letters EC in 1973 up to EZ. E was picked then as letters A-D were at that point in utilized by different states in Malaysia.[3] From 1984, the “S” series of number plates were dispatched again after EZ, however presently with two sequential postfix letters, beginning from SBA, despite the fact that with a few prefixes being skipped as they are saved, like SBS and SMB, as they were utilized for transports that have a place with public vehicle administrators. Anyway, under the Bus Contracting Model which was subsequently carried out, transport administrators under Bus Contracting Model use the SG prefix for every open transport.
