Is there a better way to check if a number is in range of two numbers

I am trying to check if a number is in range of integers and returns a number based on which range it lies. I was wondering if is there a better and more efficient way of doing this:

def checkRange(number):
        if number in range(0,5499):
            return 5000
        elif number in range( 5500, 9499 ):
            return 10000
        elif number in range( 9500 , 14499 ):
            return 15000
        elif number in range( 14500 , 19499 ):
            return 20000
        elif number in range( 19500,24499 ):
            return 25000
        elif number in range( 24500,29499 ):
            return 30000
        elif number in range( 29500,34499 ):
            return 35000
        elif number in range( 34500-39499 ):
            return 40000
        elif number in range( 39500,44499 ):
            return 45000

This felt like a waste of resources and would greatly appreciate if there is a better way to do this.
