Wow! That was fast. Others reported that it took 6 to 8 weeks for their new Amexes to report on their CR. But both my Zync and Costco are already on my EX report. They both show date opened as 2/1/87 - Thank you, God!

Of course, I have NO idea how this affects my EX FICO.  I can't wait for them to report on EQ, so I can get an updated SW FICO. I just hope that it's a BIG jump and more than makes up for 2 account balances reporting (small, though they are). 

One thing that's odd is that it shows date opened as 2/1/87, but under the 24-month history section, it only has one lonely month. So, I do wonder what potential creditors would think about this. Or current ones, for that matter. It does look odd. But I am SO grateful for backdating. It's a credit miracle!
