measurements - Number of significant figures


I am looking for an intuitive answer that will explain me why there are only two significant figures in say the number 1500.


Also definition from wikipedia:



The significant figures of a number are those digits that carry meaning contributing to its precision




So are we not considering last two zeros as meaningful ? Why like that ?
