What happens when you submit a Costco credit card request

When you request a Costco credit card, you are asking Citibank (which issues the card) to review your credit history and decide whether to approve you. The process takes a few minutes online or a few days by mail, depending on which method you choose. Citibank will pull your credit report, check your income and existing debts, and send you a decision — usually approval, denial, or a request for more information.

You do not need to be a Costco member to request the card, though you will need to become one to use it. The card itself comes with a Costco Gold Star membership, so the annual fee covers both. If you are denied, you can request reconsideration or try again after addressing the reason — typically a low credit score, recent missed payments, or too much existing debt relative to your income.

Key Takeaways

  • You can request a Costco credit card online at Costco.com or by mail; online decisions usually come within minutes, while mail requests take several business days.
  • Citibank will review your credit score, payment history, income, and existing debts to decide whether to approve you.
  • The card comes with a Costco Gold Star membership, so the annual fee ($65 for Gold Star, $130 for Executive) covers both the card and warehouse access.
  • If you are denied, you can call Citibank to ask why and whether you can reapply after making changes to your credit profile.
  • A hard inquiry will appear on your credit report and may lower your score by a few points for several months.

Requesting online versus by mail

The fastest way to request a Costco credit card is online at Costco.com. You fill out a short form with your name, address, date of birth, Social Security number, income, and employment information. Citibank's system reviews this information when ready and tells you whether you are approved, denied, or need to provide more details. If approved, your card ships within one to two weeks.

You can also request by mail using an process form available at the Costco warehouse or by calling Citibank at the number on Costco.com. Mail requests take longer — usually 7 to 10 business days for a decision — but some people prefer this method if they want to avoid the hard inquiry appearing on their credit report when ready. The hard inquiry happens either way; the timeline is the only difference.

What Citibank looks for in your credit profile

Citibank reviews four main things: your credit score, your payment history, your income, and how much debt you already carry. A credit score of 700 or higher makes approval much more likely, though people with scores in the 650 to 700 range are sometimes approved if their payment history is clean. A single missed payment in the last two years, or multiple missed payments further back, can trigger a denial even with a decent score.

Your income needs to be high enough that the credit card payment (usually $50 to $150 per month if you use it regularly) does not push your total monthly debt payments above 40 to 50 percent of your gross income. If you carry high balances on other cards or have recent loans, Citibank may see you as too risky. You can check your own credit score free once per year at AnnualCreditReport.com, which is the only federally authorized site for free reports.

The annual fee and what it covers

The Costco credit card comes with a Costco Gold Star membership, which costs $65 per year (or $130 for the Executive tier). This is not an extra fee on top of the card — it is the membership fee, and the card is included. You cannot get the card without the membership, and you cannot get the membership without the card. If you already have a Costco membership, you will need to upgrade or renew it when you get the card.

The card itself has no separate annual fee beyond the membership cost. You earn 1 percent cash back on most purchases and 2 percent on gas, travel, and dining. The cash back is paid as a Costco Cash certificate once per year, which you can use only at Costco or Costco.com. If you do not use Costco regularly, the membership fee may not be worth the cost.

What happens if you are denied

If Citibank denies your request, they will send you a letter explaining the reason — usually "credit score too low," "insufficient income," "too much existing debt," or "negative payment history." The letter will include a phone number to call if you want to ask questions or request reconsideration. Some denials can be reversed if you provide additional information (such as a co-signer or proof of higher income) that was not in the original process.

If reconsideration does not work, you can reapply after three to six months if you have taken steps to improve your profile — paying down other debts, correcting errors on your credit report, or letting old missed payments age. Each new request triggers another hard inquiry, so do not explore more than once every few months. You can also ask a friend or family member with stronger credit to be a co-applicant, though this means they are equally responsible for the debt.

How the hard inquiry affects your credit score

When Citibank pulls your credit report to review your request, it creates a hard inquiry that appears on your credit report and may lower your score by 5 to 10 points. This dip is temporary — the inquiry stops affecting your score after about three months and disappears from your report after two years. Multiple inquiries in a short time (like explore for several cards in one month) can lower your score more significantly.

A single hard inquiry is usually not a major concern if your score is already solid, but if you are close to a score threshold (like 700), it might push you below it. If you are planning to request a mortgage or car loan in the next few months, it is worth waiting to request the credit card until after that process is complete, since those loans also use hard inquiries.

Using the card once it arrives

Once your card arrives, you can use it at any Costco warehouse or on Costco.com. You will also have access to Costco Travel, which offers discounted vacation packages. The card is a Visa, so you can use it at other merchants too, though you earn only 1 percent cash back outside Costco (and no cash back on some categories). You will receive a monthly statement and can pay online, by phone, or by mail.

Your credit limit will be set when the card is approved — typically $500 to $5,000 depending on your credit profile. You can request a higher limit after six months of on-time payments. Paying your full balance each month keeps you out of debt and maximizes the value of the cash back reward, since interest charges will quickly erase any rewards you earn.

Frequently Asked Questions

Do I have to be a Costco member to request the card?

No, but you will need to become a member to use the card. The card comes with a Gold Star membership ($65 per year) or Executive membership ($130 per year), so you cannot have one without the other. If you already have a membership, you will renew it when you get the card.

How long does it take to learn about I am approved?

Online requests usually get a decision within minutes. Mail requests take 7 to 10 business days. Once approved, the card ships within one to two weeks. If Citibank needs more information, they will contact you by phone or mail.

What credit score do I need?

Citibank does not publish a minimum score, but approval is much more likely with a score of 700 or higher. People with scores between 650 and 700 may be approved if their payment history is clean and their income is stable. The only way to know is to request and see what Citibank decides.

Can I use the card somewhere other than Costco?

Yes, it is a Visa and works at any merchant. However, you earn 1 percent cash back at most non-Costco stores and 2 percent at gas stations, travel, and restaurants. The best rewards are at Costco itself, where you earn 2 percent on most purchases.

What if I am denied and want to try again?

Wait at least three to six months before reapplying. Use that time to pay down other debts, correct any errors on your credit report, or let old missed payments age. Each new request creates another hard inquiry, so do not explore more than once every few months.
