The bench said: "Everyone knows about 100. How many know of 181? Not many, we are sure. You have to make it known to the people."
It added that a women helpline number was of no use if it was not publicized properly.
The court was hearing a PIL filed by advocate Gaurav Bansal which cited surveys by independent groups claiming a spurt in crime against women and sought directions for taking adequate steps to prevent it.
The PIL pointed out that the Delhi government had failed to provide an atmosphere conducive to the growth of girl students and women.
The PIL submitted a press release issued by Delhi Police in April last year which said incidents of molestation and eve teasing had recorded 600 percent and 783.67 percent rise respectively in recent years.
