USCF PIN

I am a member of USCF, but I lost my PIN number. This PIN is required for tournaments and such. Every USCF page where you can request your PIN gives me a 404 not found, such as:

I have also tried to contact them via phone, but their membership team is OOO due to Covid. Does anyone here know of any resources I can use to get my USCF PIN? Thanks!

US Chess is no longer providing PINs as of their system updates in July.  You have to use the method in the following for any online sites that are partnered with them.

Is this association between chess.com username and USCF player info exposed to the public?

I'm a little concerned about the following hypothetical sequence of events: make an anonymous reddit account, make a chess.com account with the same username, attach chess.com account to USCF account to play in tournaments, whoops -- no longer anonymous on reddit... hope you didn't ever say anything controversial.

The direct link on the US Chess site is not but the form you have to fill out to play in the Members Only club is made available for other affiliates on chess.com to use (slightly sanitized and only includes ID, Username, name and expiration date that is only updated on renewals). Also, if you play in any rated events online, the link is trivial to find anyway.
