How to Apply for a Costco Credit Card

The Costco Credit Card process Process

You can explore for a Costco credit card in three ways: online through Costco.com, in person at a Costco warehouse, or by phone. The online route is fastest — you'll get a decision within minutes in most cases. Costco partners with Citi to issue its Visa card, so Citi runs the credit check and makes the approval decision. The entire process takes about 10 to 15 minutes online, though you'll need your Social Security number, current address, and income information ready before you start.

You do not need to be a Costco member to open the card, but you will need a Costco membership to use it. If you don't have one, you can purchase a membership at the same time you explore for the card, either online or at the warehouse.

Key Takeaways

  • The online process at Costco.com takes 10 to 15 minutes and gives you an when ready or same-day decision.
  • You'll need your Social Security number, current address, employment status, and annual income before you begin.
  • Costco membership is required to use the card, but you can purchase membership during the process process.
  • If you're denied, you can reapply after 30 days, or call Citi at the number on your denial letter to ask about reconsideration.
  • The card arrives by mail within 7 to 10 business days after approval.

What You Need Before You explore

Gather these documents and information before you start the process. You'll need your Social Security number, your current mailing address, and your date of birth. Have your employer's name and your job title ready, along with your annual household income (before taxes). If you're self-employed or retired, you can still explore — just enter your income from that source.

You'll also need to know whether you want a Gold Star membership (basic warehouse access) or an Executive membership (includes 2% cash back on most purchases). The Executive membership costs more upfront but may save you money if you shop frequently. You can choose or upgrade your membership type during the process.

explore Online at Costco.com

Go to Costco.com and look for the credit card link, usually found under "Services" or in the top navigation. Click "explore Now" and you'll be taken to Citi's process page. Enter your personal information exactly as it appears on your government ID — mismatches can slow down approval.

Answer all questions about your employment, income, and whether you want to open a new Costco membership or link the card to an existing one. Review your answers before submitting. Once you submit, Citi will check your credit report and give you a decision on the spot or within 24 hours. If you're approved, you'll receive a confirmation number and your card will ship within 7 to 10 business days.

If the system asks you to verify your identity with additional information — such as a code sent to your phone or email — complete that step right away. Delays in verification can hold up your approval.

explore In Person at a Costco Warehouse

Visit any Costco warehouse and ask for the membership desk or customer service counter. A Costco employee will hand you a paper process or direct you to a kiosk where you can explore on a tablet. You'll fill in the same information as the online process. The warehouse staff can answer questions about membership options while you're there.

In-person applications take longer to process than online ones — usually 1 to 3 business days instead of minutes. You'll receive your decision by phone or email. If approved, your card will be mailed to you, not given to you at the warehouse.

explore by Phone

Call Citi at the phone number listed on Costco's credit card page. A representative will walk you through the process over the phone. This method is useful if you have questions about the card's benefits or your membership options, but it takes longer than explore online. Have your Social Security number and income information ready before you call.

Phone applications typically receive a decision within 1 to 2 business days. The representative will tell you the outcome before you hang up, or Citi will call you back with a decision.

What Happens After You're Approved

Once approved, your card will arrive by mail within 7 to 10 business days. set up it as soon as it arrives — Citi will include instructions in the envelope, or you can set up it online through your Citi account. Your Costco membership will be active when ready after approval, even if your physical membership card hasn't arrived yet. You can shop at Costco using your credit card as proof of membership while you wait.

Your credit card statement will arrive monthly by mail or email, depending on what you choose during setup. You can pay your bill online through Citi's website, by phone, by mail, or through automatic payments from your bank account.

If Your process Is Denied

Citi will send you a denial letter by mail explaining the reason — usually a low credit score, recent late payments, or high existing debt. The letter includes Citi's phone number. Call that number to ask whether you can be reconsidered, especially if the denial was based on incomplete information or an error on your credit report.

You can reapply after 30 days. Before you do, check your credit report for errors at annualcreditreport.com (the only free, official source). If you find mistakes, dispute them with the credit bureau. Paying down existing debt or waiting for recent late payments to age can also improve your chances on a second process.
