My credit card for autopay has an outdated zip code, which I thought might be the reason the card was rejected; however, when I tried to correct my card info, T-mobile’s site claims that my credit card number is invalid . . . this is completely incorrect and I use it for other things.  How do I get this fixed?  I can’t even make a payment with my card because of this.

First, did you change the zip code with the credit card first, then try to change it on the Tmobile site? If so, how long did you wait for the credit card company to update their info? Everything seems to go at a snails pace these days…

If your payment is due soon, perhaps you should call and make a payment by phone this month.:wink:

Yes, my credit card was changed and works fine with the new zip code.  The issue is with Tmobile.  I can’t even update my zip code here because the site claims my credit card number is invalid, which is completely untrue.  I was wondering if there’s some systematic issue with T-mobile today or what.  I tried to enter my card information in as a new card and it rejects the card number as invalid.

Does your home address on your Tmobile account have the same address as your credit card?

I’m having the same issue as you OregonLady80. For three days now I’ve ben trying to add funds to my account for my next payment that is coming due. And everytime I try to add my credit card details, which have always worked in the past. It says invalid card number, no matter which credit card I use. Please fix this glitch tmobile. I’m using Mozilla Firefox browser and have never had this issue before. Seriously, fix it please! Thank you.

You can either call Customer Care and have them add your card manually or make a payment in your local T-Mobile Store.  The account system has been broken for quite some time and it isn’t getting any better with time.  

I encountered the exact same problem in Firefox 68.12.0esr on Windows 8.1 when trying to place an order - I typed in the card number correctly, and it complained “Card number is invalid. Please try again.”.

When I tried again using Microsoft Edge 44.19041.423.0 on Windows 10, the card number was accepted.

I just had to go through this crap again!  I tried the above but no success.  I even checked the version of Edge I was using.  This is getting annoying!  If I have to call in every month to re-add my card and pay early.  I am going to get to the point where I am going to take our 3 lines and port them out to a carrier who has a competent billing and account system!
