I use them; using houses is quite new to me so I count up the card position and find that number so I know what house it's in. I have never been able to memorise the order of the cards, so the numbers are useful to me.
I copied a page out of Rana George's book that has a simple name and number house layout. I keep it in my journal for reference. Very helpful. You could make one using Excel or another word processing program. I made an 8X8x4 layout to use write down my Grand Tableau spreads on Excel.
