RP from O5: Name change & credit reporting agencies

This post was on a DC board I frequent and it got me thinking...anyone know anything about this?:

' I called Transunion, and they said that I just needed to switch my name with the credit card companies and then it would automatically be switched with them as well. Well, I ordered a free credit report to make sure, and sure enough, my name is changed, but I have NO credit history before Nov 2005 (when I changed my name). What to do? I've been building great credit for years and now it's like I never existed. Has anyone else looked into this? TIA!'

From Experian's website it also says:


Women who take their husband's surname after getting married need to notify the Social Security Administration and their current creditors of this change. You do not need to notify the credit reporting agencies of a name change. They will automatically update the name on a credit report when creditors report it.
