There is no such REST method as  PUT "rest/api/2/issue/username". I am not sure what you are trying to do but the closest method is PUT "rest/api/2/issue/{issueIdOrKey}" that updates issue.

Maybe "by validate JIRA number" you mean check for existence of an issue. Then you can use GET /rest/api/2/issue/{issueIdOrKey}.
