So this national public data breach, has been really successful, hence I froze my files. Its the first time my SSN showed up publicly.

Is there a way I can see the full data they have from that breach?

Better to call or send a letter the agencies rather than create an account. Creating an account can subject you to an arbitration clause against the agency which may not be favorable if you end up with a credit report error that you have to litigate. Trans Union also was recently sued by the CFPB for looping “account holders” into hidden fees and subscriptions. Not legal advice

As for all three at once, it’s just one trip to the post office to mail three letters, if that counts

“Credit monitoring bundles also have a hidden cost. Buried in the fine print of their agreements are forced arbitration clauses. These clauses prevent consumers from going to court to enforce their rights and force them into a private adjudication where the deck is stacked in favor of corporations. Credit monitoring bundles can be expensive and ineffective, and they do not prevent identity theft. Even worse, they may prevent consumers from filing a lawsuit for errors in their credit reports. The “Big Three” credit reporting bureaus (Experian, Equifax, and TransUnion) are major providers of credit monitoring services. At least one of these credit bureaus — Experian —includes a broad arbitration clause in its terms and conditions that may prevent consumers from suing over errors in their credit report, even when those errors are unrelated to credit monitoring.”
