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.
Note that, before this incident, it wasn’t consistently free. I remember it being free to lock, but costing $20 or so to unlock. A law passed in 2018 required credit bureaus to offer freezes and unfreezes (and to fulfill them within certain time frames) for free.
Also note that you might need to look for a “freeze” instead of a lock. Experian charges $25/month for their “CreditLock” service, for example, but they offer a free security freeze.
Interesting, I just tried to lock my credit and was prompted to pay for a premium account to do so.
