All depends on your residency you validate with the Bank and IB, eitherway IB will require you to complete W8BEB form and do their own
KYC.
Digging into the IB website from the Bank in question. if the IB Branch linked to the
Bank Account is in
CRS juristication such as HK then they will report as you would be an account holder in IB HK. I see there is also Global IB account, that discusses FACTA & CRS.
Also IB want your TIN/SSN, employer details, they may even ask for residency proof, Bank Statement may placate them or if not in country of passport they may ask for visa proof, rental agreement depends on how strict they are for KYC.
IB focused on US Markets then the reporting will be based on your country of residence & US DTA, in some DTA there are articles of "automatic exchange of information". (not sure if it is automatic or by request because most Banks/Brokers report or reject US citizens automatic based on FACTA, someone in the know may jump in I hope).
So if you seeking to circumnavigate reporting while
investing it is doable but just by going thru a non CRS may not make a difference read your DTA.
Some discussion here on similar
Hi all, I would like to use brokerage services to buy funds, ETFs and stocks offshore with privacy from CRS. What banks can you recommend with low fees and stability?

I did see an article recently where some swede or danish nationals where caught out from their home country having USA Broker Accounts but thus thru their use of the USA Based Broker MasterCards they were using at home. This suggests they may havechad the accounts and they were not being reported automatically but their card use put them on the radar.
Your relevant DTA agreement, in example some specifically state the DT Agreement is only related to US and not its territorial islands such as Puerto Rico that therefore gives on option for some residents to bank there on this basis. (risk remains but less maybe) for EPB though their Brokerage is in a CRS reportable jurisdiction.
Your DTA though would allow you to recover some of your Tax, paying 30% on
dividends etc. there are better ways to invest in the US indirectly.
If you are in a non CRS country then invest in a reportable CRS, to reduce the 30% US WHT, but again look at the DTA with that country and yours, there may not be automatic exchange of info by governments definitely wont be by banks/ brokers
