I have had my number on my bin since day 1. Self adhesive numbers can be bought at any DIY store or garden centre.
My (very slight) grumble is that my house is one of three on a small access road and we have to put our bins where the access road reaches the road, no problem with that, but when we put them out we put them on the grass verge so that vehicles can get on the access road to the houses. The bin men often leave the bins in the middle of the access road by the pubic road and, as the road is narrow with parking on one side, if you are returning home, you have to stop, get out of the car, move the bins, get back to car and then start up again, holding up all traffic going in both directions while you do so.
