Hi, upgrading online for multiboxer is often the preferred method when you have 5 accounts - who wants to be seen buying 5 accounts of wow at the local store?

But, the blizzard online account upgrade page will often return INVALID CREDIT CARD for many many people, and almost all foreign people (I am in Canada and I get the message). This is because their page does one US security checks and one blizzard check. I spent about 2 weeks trying to get it to work, as my credit cards works for the subscription just fine.


The first check is your name. It states that you need to enter your name as it appears on the credit card. This is false. My name on the credit card is Alexandre H Tremblay. But the name I registered with is Alexandre Harvey-Tremblay. So I have to enter the name I registered with and NOT the name on my credit card.

The second check is your postal code. In canada, we have postal code of the form J9J2X2. In the US, the last 4 digit of your credit card is your zip code, so the blizzard page checks for it. You must enter the last 4 digits of your credit card in the zip code textbox and it will work.

So to all those who have a pain trying to upgrade online, do this and it will work like a charm!

Good luck.

eh? None of this matched my upgrade information. In fact the name on some of my accounts are peoples names I just made up from my work. Also, in the US, the last 4 digits of all my credit cards are completely different and none of them match my zip (postal) code. Not sure where you got that information from. I only upgraded one account online to Wrath of the Lich King. All others were from the packages bought from newegg.com. That one account had a different name on the account than what was on my credit card. And I was able to do the online upgrade using my credit cards name, not the registered name on the account.
