You can report a lost Costco Credit Card by calling Citibank customer service at 1 (800) 950-5114. You can also report a lost Costco Credit Card through the Citibank website or mobile app. Citibank will request some security information in order to verify your identity before sending a replacement.
Inform the customer service representative that you’ve lost your credit card.
Provide any requested information, such as your date of birth or the last four digits of your SSN.
Ask the Citibank rep to cancel your old credit card and send a replacement.
You should receive a replacement Costco Credit Card within 5-7 business days. When you receive your replacement Costco Credit Card, you’ll need to activate it before you can make purchases. And if there are any recurring charges linked to the old Costco Credit Card, make sure to update those accounts with your new card information.
Finally, it’s important to note that your Costco Credit Card is covered by $0 fraud liability, which means that you will not be held responsible for unauthorized purchases made with your card while it’s lost. You should still give your card issuer immediate notice of any unfamiliar charges on your account, though.
Yes, you can use a credit card before it arrives in the mail, but only with certain cards. If you want to use a credit card early, you must either have an American Express or Capital One credit card or one of a handful of other offers, including the Apple Card, and some store credit cards. Normally, you can’t use a credit card without restriction before it arrives, because you can’t see the full credit card number, expiration date and CVV until you have the card in hand.… read full answer
Credit cards that you can use before arrival
Cards from certain issuers: If you need to start using a credit card today, you’ll likely want to consider applying for an American Express credit card. Amex is one of the few card issuers that will give out a full card number that can be used anywhere upon approval of an application. Capital One credit cards are also sometimes available for immediate use via the Capital One mobile app. But not everyone is eligible for this feature.
Co-branded cards: Some credit cards that you can use before the actual card arrives - like the Apple Card - only allow you to add the card to a merchant-specific digital wallet. So you’ll only be able to use it with that merchant until the card arrives in the mail.
Some store cards: There are a few credit cards that you can use instantly after approval, like the Fingerhut Credit Card. But you can only use this card for purchases at Fingerhut.
Lastly, it’s worth noting that you can ask a credit card issuer for expedited card delivery – in some cases, this will get the card to you the next day. Finding a card that you can use before it arrives in the mail might seem less important with that in mind.
