Freezing/unfreezing does nothing to your credit score. Also, looking up your credit score and pulling a report for personal reasons (read: not a credit line application) will NEVER affect your score. It's what they call a soft credit inquiry, which is not shown on your report when creditors pull it, and won't factor in to credit score calculations. https://www.creditkarma.com/article/hard_inquiries_and_soft_...

It does not affect your credit rating for freezes and unfreezes. And it's a good thing that hard pulls on your credit affect your score, because it's a stop gap for excessively requesting credit. It can also prevent heavy fraud because creditors will often reject potential customers with too many hard pulls.
