Why YSK: Locking your credit with the main 3 places is not enough.
https://innovis.com/ have grown enough to require locking as providers are using them as a single check source.
There’s also https://www.chexsystems.com/ which many banks use for opening checking accounts. They’re unique because they handle accounts that don’t show up in a credit report.
I’ve been under my parents plan my entire life and I was able to lock my credit with Innovis. Granted, this was right after the Equifax breach. I’ve actually never had to unlock it.
