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.
This does apply in other countries, like the UK. But not all countries use the same companies.
I looked into it and so far it’s only in Québec.
