Not only would that not help your thieving at all, but the company that hired you having all your info on file would make you much more likely to get caught. Assuming you are robbing houses you can deliver too.
Putting on a fake delivery uniform and carrying around boxes that aren't meant to be delivered makes a lot more sense if you just need to case the houses before robbing.
plenty of people have life long careers of house burglary.
here are two, but there are very many others.

Yes. Fedex, UPS, and USPS drivers clearly have a much better grasp of how to correctly handle delivery exception scenarios. That's probably because they actually train their employees, and schedule them so they can learn their routes. You're never going to get that with with the short-term gig-economy randos Amazon hires.
