It looks to me like the year of birth marker ends in a 9. It looks like there may have been something above that, but it's hard to tell. Could be 2019? 2009? 1999?
After that it looks to me like the first number of registration is the ^ shape which is 3.
Then the 2nd registration number is 2.
Then maybe the 2 vertical lines possibly, 1.
I can see remnants of the last 3 marks but couldn't tell you what they are as it's just some white hairs and not really a shape at that point.
That's what I see.
Wanted to add, 321###, seems to be from Idaho.
