You cannot pre-qualify for an Amazon Credit Card. Neither the Amazon Visa Credit Card nor the Amazon Store Card offers pre-qualification. You will need to submit an actual application to find out if you qualify for the card.
Do cobrands show up for Chase members when checking for offers via the Chase web site?
I have Chase checking and savings accounts, but I've never had a card offer (lol/24), so I don't know if it's only core cards there.
it should be this link: https://www.amazon.com/Amazon-Rewards-Visa-Signature-Card/dp/B007URFTYI
you have to be signed in on your amazon account I think.
The prequalify link can be found on the Amazon page for the card, as noted above, but it isn't always available. It comes and goes seemingly at random for me.
Every time I try to use it, however, it tells me it couldn't check my credit to prequalify me because my Experian report is frozen. I routinely keep my reports frozen, but always thaw them before trying to prequalify, obviously, but for some reason Amazon/Chase sees them as still being frozen even hours after temporarily lifting it.
I keep receiving the same error about my report being frozen despite never having any of my reports locked.
Not sure whether the pre-qual link from Amazon is sufficiently legit. I got my Chase Amazon card several years ago and I still get those pre-qual notifications via Amazon. I think, one Amazon card per house is sufficient
