From lines in a file i would like to find those that

• the lines starts with a year YYYY ^(202\d) for example 2022or 2023
• followed by at least 1 and up to 4 uppercase letters ABCD [A-Z]{1,4} or up to 3 numbers \d{1,3} and at least one letter [A-Z]{1} for example ABCD or A123 or 1A23 or 123A
• followed by either A or R

Examples

YYYYxxxxA   // find rows that match 2022xxxxA
2022A150A   // relevant matches
2022B260A   //     "
20223A70A   //     "
20224B84A   //     "
20224B  A   // not relevant due to spaces \s\s 
20221234A   // not relevant due to 4 digits and no letter

In visual-studio-code i tested javascript regex (see my demo@regex101.com)

These two regex seem to work

2022(\d\D\w\w|\D\d\w\w|\d\d\D\w|\d\d\w\D|\D\D\D\D)A
// or
^(202\d)(\d{0,3}[A-Z]{1,4}|[A-Z]{1,4}\d{1,3})([\dA-Z]{0,4})A

Explanation from regex101.com

• at start of a line
• 1st Capturing Group (202\d) matches 202 literally and \d matches a digit (equivalent to [0-9])
• 2nd Capturing Group (\d{0,3}[A-Z]{1,4}|[A-Z]{1,4}\d{1,3})
• 2 Group 1st Alternative \d matches a digit (equivalent to [0-9]){0,3} matches the previous token between 0 and 3 times
• 2 Group 1st Alternative match a single character present in the list below [A-Z] {1,4} matches the previous token between 1 and 4 times
• the other alternatives | are a variation of the first

Question

I would like to know if there is a better option than

^(202\d)(\d{0,3}[A-Z]{1,4}|[A-Z]{1,4}\d{1,3})([\dA-Z]{0,4})A

for (xxxx) should contain at least 1 uppercase and no more than 3 digits?

Test with my demo
