Example: Waller is Area 26 How do I find out what the other area numbers are?

Hey Kimberly, Great Question. When you are in Matrix, open the Map tab and zoom in slightly. Find the drawing tools (Radius, Rectangle, Polygon), then hover over the button with an icon of three stacked sheets of paper labeled "Layers." Click it and select the layer titled "MLS Areas." This will display the areas and their boundaries. I hope this helps!
