I don't know if any of this helps, but 317 can be a slang term for cannabis or a stupid person. 469 can be a slang term for a leader, and it's an angel number as is 553.
I'm not endorsing this site btw, it does seem a lot of bollocks.
574 could refer to Indiana or Aberdeen.
635 is another angel number same link as before.
I think I've probably just muddied the waters even more, but good luck.
Do you have any other context?
