I've had no problems. Someone will try to run my credit, it will fail, then I ask which one they're trying to use, and I unfreeze it for a day. Some of them have the option to unfreeze for a single pull with a 1 time code (if I remember correctly), but when I tried to use that the person trying to pull the report seemed clueless, so I had to do the 1 day unfreeze.
At some point, I wonder if folks will realize that having an unfrozen credit report is a sign of imprudence.
Also, all the big bank websites seem to offer real time credit history monitoring for free, so I am betting I’ll just deal with any problem if/when they happen.
Doing all 3 takes ~5minutes now - which can usually happen in parallel with whatever paperwork the vendor needs to get in order.
