Number plates can be a great way for the Universe to give us messages, because they contain both words and numbers, and I have had experiences of when they have manifested with messages for me. When I was going for a job interview, I saw things like DAD, POP and the names of my grandparents (all passed spirits and now acting as my spirit guides) as if to say that my guides were with me and helping me. I got the job easily.
Years ago, I had a big issue in my life and didn't know how to solve it myself. On the way home from work I was thinking about God having a perfect answer instead of me, and then saw a number plate saying YE5 1 DO. Message received there too.
