Number plates of Tanberlot

Tanberlot was formerly a Swedish colony. The first number plates followed the 1906 Swedish format (TN instead of a county alphabetical code), and were used until 1914 (format: TN-1234), when it was replaced to show an all-numeric three to six-digit format with "TANB. 1914" on the left (not part of the plate number). The vehicles replaced the plates yearly as with the United States until 1977. The current number plate format is a three to seven-digit plate number and a check digit (no check digit is included for special use vehicles, except for diplomatic vehicles, and in number plates issued by class D registration offices).

Personalised number plates may include a check digit, but if the digits preceding the check digit are letters only, the checksum letter is used. It is based on the “Luhn mod n” algorithm.

History
Until 1914, Tanberlot’s number plates were the code TN followed by a four digit number.

In 1914, this was changed into an all numbers format, with “TANB. 1914” printed to the left of the serial number. In 1926, “TANB. (year)” is placed on the top of the number plate.

By 1936, “TANB. (year)” was replaced by “(first two digits of year) TANBERLOT (last two digits of year)”.

Since 1973, a checksum, mod 9, is included.
