times more of the number space that a single nine digit number. Thus the levy for a single three digit number should be one million times the levy imposed for holding a single nine digit number. If the levy for a single nine digit number is LAK 2 500, the uncapped levy for the three digit number would be LAK 2,500,000,000. A cap on the levy for a single number is used in Australia. A simple rule of thumb could be that the levy cap is 10 thousand times the base rate levy. Such a cap would in the above example limit the levy on a three digit number to LAK 25,000,000.
