Indigo Apply Pre-Approved Invitation Not Working? What to Do

If your Indigo pre-approved invitation is not working when you try to apply for the Indigo Mastercard®, there are several things you can check before giving up on the offer. The problem may be something as simple as an incorrectly entered Application Code or ZIP code, but there can also be technical problems that prevent the invitation from being processed.

This guide explains what to check if your Indigo invitation isn't working and what you can do if you still cannot get the offer to work.

Is Your Indigo Offer Not Working or Not Available?

There is a difference between an Indigo invitation that is not working and one that is showing as not available. If you have an invitation but the application code isn't working or the offer isn't loading correctly, the troubleshooting steps on this page may help.

If Indigo specifically says that your pre-approved invitation is not available, the issue may be that the offer is no longer available. See Indigo Apply Pre-Approved Invitation Not Available to learn what you can do next.

Why Did I Receive an Indigo Invitation?

If you received an Indigo invitation in the mail, you can learn more about why you received the offer in our article Why Did I Receive an Indigo Apply Invitation in the Mail?.

How to Use Your Indigo Offer

For information about using your Indigo application code and accessing your offer, see indigoapply.com: How to Use Your Indigo Card Offer.

Check Your Indigo Application Code

If your Indigo apply invitation is not working, the Application Code is one of the first things you should check.

  • Make sure every number and letter has been entered correctly.
  • Check the code against the original mail offer.
  • Make sure you are using the correct code if you have received multiple offers.
  • Do not substitute another number printed on the offer for the Application Code.

A small entry error can prevent the system from recognizing the invitation, so carefully rechecking the code is worthwhile before assuming there is a problem with the offer itself.

Check Your ZIP Code

The ZIP code you enter should correspond with the information associated with your Indigo invitation. Carefully check the ZIP code before submitting the invitation information.

If you recently moved or your address has changed, this may also be something to consider when an invitation does not work as expected.

What If the Indigo Invitation Page Isn't Working?

If the Application Code and ZIP code are correct but the page still isn't working, the problem may be related to your browser, device, or the website itself.

  • Try opening the application page in another browser.
  • Try using a different device.
  • Clear your browser's cache and cookies.
  • Make sure your browser is up to date.
  • Temporarily disable browser extensions that may interfere with the page.

If the page works on another device or browser, the problem may have been technical rather than related to your invitation.

What If My Indigo Invitation Still Doesn't Work?

If you have carefully entered the Application Code and ZIP code and have tried accessing the invitation from another browser or device, but the offer still will not work, contacting Indigo may help determine whether there is a problem with the invitation.

Have the original mail offer available when contacting customer service so you can provide the information printed on it if necessary.

Try the Indigo Pre-Qualification Form Instead

If you cannot get the mail invitation to work, an alternative is to use Indigo's pre-qualification process to see whether you may qualify for an Indigo credit card.

Pre-qualification is different from submitting a full credit card application. The pre-qualification process uses a soft credit inquiry, which does not affect your credit score. If you decide to continue with a credit card application after being pre-qualified, the application process may involve a credit inquiry.

This can be a useful alternative if your invitation code or invitation page simply will not work and you want to find out whether you may qualify for an Indigo card without immediately submitting a full application.

➤ CLICK HERE TO CHECK FOR INDIGO PRE-QUALIFICATION

There is no guarantee that you will be approved, but pre-qualification can give you another way to check your potential eligibility when you are unable to use the invitation offer.

The pre-qualification option is particularly useful to consider when you have already tried to use the invitation and cannot get the offer to work.

Final Thoughts

If your Indigo pre-approved invitation is not working, start by checking the Application Code and ZIP code and making sure you are using the correct Indigo application page. A browser or device problem can also prevent the invitation from working properly.

If you have tried these steps and still cannot get the invitation to work, you do not necessarily have to stop there. The Indigo pre-qualification option provides another way to check whether you may qualify for an Indigo credit card using a soft credit inquiry.

That makes pre-qualification a reasonable alternative for someone who received an Indigo invitation but is unable to get the invitation offer to process online.

If your Indigo pre-approved invitation eventually works but your application is not approved, that's a different situation. Learn what an Indigo pre-approved invitation not approved decision means and what you can do next.

FICO® Credit Scores

A FICO® Score is a proprietary credit score created by the Fair Isaac Corporation (FICO). About 90% of top U.S. lenders use it to make lending decisions.

FICO® Score Ranges:

  • Exceptional: 800–850
  • Very Good: 740–799
  • Good: 670–739
  • Fair: 580–669
  • Poor: 300–579

FICO categorizes scores as Poor, Fair, Good, Very Good, and Exceptional.

What is a Credit Score?

A credit score is a three-digit number (300–850) predicting your creditworthiness. Lenders use it to evaluate risk and determine rates and terms for credit.

Why it matters: A higher score can help you qualify for loans and lower interest rates. A lower score can lead to higher borrowing costs or application denials.

FICO® Credit Score Facts

Key Characteristics:
  • Three-Digit Number: Summarizes your credit risk.
  • Range: 300–850; higher scores = lower risk.
  • Data Source: Uses your credit reports from Experian, Equifax, and TransUnion.
  • Industry Standard: Lenders rely on FICO for mortgages, auto loans, and credit cards.

Note: Credit scores reflect your creditworthiness but do not guarantee approval for any credit product.
