Key Points

• Citi is ending point transfers between different cardholders on May 17, 2026, but you can still combine your own ThankYou accounts.
• Profile information must match exactly across all accounts before the combine option appears online.
• Small details like missing phone numbers or extra spaces can prevent account combination, but these are easy to fix.

Introduction

If you have multiple Citi credit cards earning ThankYou points, you're probably managing separate point balances across different accounts. Here's what most cardholders don't realize: you can pool all those points into a single ThankYou account, making them easier to track and use for transfers to airline and hotel partners.

This matters more than ever. Citi recently announced they're ending point transfers between different cardholders on May 17, 2026. While this doesn't affect your ability to combine your own accounts, it's sparked confusion about what's still possible. The good news? Combining your own ThankYou accounts remains fully supported, and it's actually simpler than most people think once you know the trick.

Why Combining ThankYou Accounts Matters Right Now

The Big Change: Starting May 17, 2026, you'll no longer be able to share or transfer ThankYou points to another person's account, even family members. This feature, which allowed up to 100,000 points transferred per year, is being discontinued entirely.

What's NOT Changing: You can still combine multiple ThankYou accounts that belong to you. If you have a Citi Premier, Double Cash, and Custom Cash, for example, all those points can live in one place.

Here's why this is valuable. When your points are scattered across separate accounts, you need to remember which card earned which points. If you cancel a card, points from that specific account expire after 60 days unless you've transferred them to a partner. When accounts are combined, all your points pool together, making it easier to reach redemption thresholds and manage your balance.

The catch? You need to be more careful about card cancellations. With combined accounts, it's harder to track which points came from which card, so downgrading cards instead of canceling them outright becomes the smarter move.

Understanding the Difference: Combining vs. Sharing

Let's clear up the confusion. There are two completely different features that people often mix up.

Point Sharing (Ending May 17, 2026): This was Citi's feature that let you transfer points to another cardholder's account. You could send points to your spouse, friend, or anyone else with a ThankYou account. This is what's being discontinued.

Combining Accounts (Still Works): This pools multiple ThankYou accounts that belong to you into a single account. When you combine accounts, your Citi Premier points, Double Cash points, and any other ThankYou-earning cards all show up as one balance. This feature isn't going anywhere.

The confusion happens because historically, people used the "Point Sharing" tool to move points between their own cards when they hadn't combined accounts yet. That workaround won't be available after May 17th, but the proper account combination feature will still work.

How to Combine Your ThankYou Accounts Online

The easiest way to combine accounts is through ThankYou.com. Here's the complete process, including the critical step most people miss.

Step 1: Log Into ThankYou.com

Go to ThankYou.com and log in. If you have multiple ThankYou-earning cards, you might see a screen asking which card account you want to use. Pick any of them to start.

Step 2: Navigate to My Citi Accounts

Once logged in, look at the top right corner where your points balance displays. Click on that balance, then find "My Citi Accounts" in the left-side menu. Click it.

Step 3: Check What You See

This is where things get interesting. You should see a list of your Citi ThankYou accounts on this page. What happens next depends on what you see:

Scenario A: You see multiple accounts listed AND there's a button to "Combine Accounts" or similar. If this is you, you're golden. Click the button and follow the prompts to merge your accounts. It's straightforward from here.

Scenario B: You only see one account, or you see multiple accounts but NO combine button. This means your profile information doesn't match exactly across accounts. Don't worry—this is fixable, and it's what the rest of this section addresses.

Step 4: The Profile Matching Secret (Critical!)

Here's what Citi doesn't tell you clearly: the combine accounts option only appears when your profile information matches exactly across all ThankYou accounts. And when we say "exactly," we mean character-for-character identical.

Click on your initials in the top right corner, then select "My Profile" from the dropdown menu. You're now looking at your profile information for whichever account you're currently logged into.

Step 5: Compare Every Single Field

This is where most people get tripped up. You need to check these fields across all your ThankYou accounts:

• First Name
• Last Name
• Email Address
• Street Address (including apartment numbers)
• City, State, ZIP
• Home Phone
• Mobile Phone
• Work Phone

The most common culprit? Phone numbers. One account might have both a home phone and mobile phone listed, while another account only has a mobile phone. Even if it's the same number in both fields, if one account is missing that "Home Phone" entry entirely, the system won't let you combine.

Step 6: Make Everything Match Exactly

Here's the process:

1. Write down all the information from your first ThankYou account
2. Log out and log back in with a different ThankYou card
3. Navigate to My Profile again
4. Compare field by field
5. Edit any fields that don't match to make them identical

Common Issues to Watch For:

• Extra space at the end of an address ("123 Main St" vs "123 Main St ")
• Different email addresses
• Phone number in one field but not another
• Slightly different name format ("Robert" vs "Bob")
• Missing apartment number on one account

Make the changes in each account's profile. Save them. This is important: changes might take a few minutes to process in Citi's system.

Step 7: Try Again

Log out completely. Log back in to ThankYou.com. Navigate back to "My Citi Accounts." If you've matched everything correctly, you should now see the option to combine your accounts.

Click that button. Follow the prompts. Your accounts will merge, typically within a few minutes. All your ThankYou points from different cards will now show as one combined balance.

What If the Online Process Doesn't Work?

Sometimes you'll do everything right, but the combine button still doesn't appear. Or maybe you see it, but clicking it produces an error. This happens.

Call ThankYou Customer Service: 1-800-THANKYOU (1-800-842-6596)

Important: This is NOT the number on the back of your credit card. That connects you to Citi's credit card customer service, and they can't always help with ThankYou account issues. You need ThankYou's specific customer service line.

When you call, be very clear about what you want: "I need to combine my ThankYou accounts." Do NOT say you want to "share" or "transfer" points, as that might confuse the agent into thinking you're trying to send points to another person.

What to Tell Them:

• You have multiple Citi cards earning ThankYou points
• You want to combine your ThankYou accounts
• You've verified your profile information matches
• The combine option isn't appearing or isn't working

Hidden Profile Fields: Here's something important. Some profile fields might be filled in on Citi's end but not visible to you on the website. The most common example is birthdate. One card might have your birthdate saved in the system while another doesn't, but you can't see this field in your profile to fix it yourself. A customer service agent can spot these invisible mismatches and fix them.

Be patient. Some phone agents are more knowledgeable than others. If the first person can't help or tells you it's not possible, politely end the call and try again. You'll likely get someone who understands the process.

Should You Actually Combine Your Accounts?

Combining accounts makes life easier, but it's not always the right choice for everyone. Let's look at both sides.

Reasons to Combine

Simpler Management: One balance is easier to track than three or four separate ones. You'll always know exactly how many points you have for that award flight.

Easier to Reach Thresholds: Need 80,000 points for a business class ticket? If you have 50,000 in your Premier account and 30,000 in your Double Cash account, combining gets you there instantly.

Better for Point Transfers: When transferring to airline partners like Singapore KrisFlyer or JetBlue TrueBlue, you only need to initiate transfers from one account instead of juggling multiple.

Less Mental Overhead: You won't need to remember "Did I earn these points on my Premier or my Custom Cash?" when deciding whether to cancel a card.

Reasons Not to Combine

Harder to Track Point Origins: Once combined, you can't easily tell which points came from which card. This matters if you cancel a card because points from that specific card expire 60 days after cancellation.

Card Cancellation Risk: If you like to cancel cards after getting bonuses and downgrade others, separate accounts give you more clarity. You'll know exactly which points are at risk when closing a specific card.

Flexibility for Household Strategies: Some households prefer keeping ThankYou accounts separate to maximize flexibility, though with point sharing ending, this becomes less valuable.

The Smart Middle Ground

Here's what works for many people: combine accounts once you have a core set of ThankYou cards you plan to keep long-term. If you're holding a Citi Premier for the transfer partners, a Double Cash for everyday spending, and maybe a Custom Cash for bonus categories, combining makes sense.

But if you're actively churning Citi cards and planning to close some in the next year, keeping accounts separate gives you better tracking until you settle into a stable card portfolio.

Real-World Scenarios

Scenario 1: The Premier + Double Cash Holder

Sarah has a Citi Premier (earning 3x on travel and dining) and a Citi Double Cash (earning 2% flat). She uses the Premier for categories, the Double Cash for everything else. She combined her accounts because:

• She plans to keep both cards indefinitely
• She transfers points to airline partners regularly
• Having one balance makes it easier to know when she's reached transfer thresholds
• She's not planning to cancel either card

Scenario 2: The Bonus Chaser

Mike has three Citi cards: Premier, Custom Cash, and Rewards+. He got them over the past 18 months for the signup bonuses. He's NOT combining because:

• He might cancel the Rewards+ after a year
• He wants to track which points came from which card
• He's considering whether to keep paying the Premier annual fee
• Separate accounts help him make those decisions with better information

Scenario 3: The Recent Convert

Jessica just learned about combining accounts after reading about the point sharing changes. She has a Premier and a Double Cash with about 45,000 points in each account. She combined them because:

• She was planning to transfer 80,000 points to Singapore KrisFlyer
• Combining got her there immediately without waiting to earn more
• She uses both cards regularly and has no plans to cancel
• Managing one balance is simpler

Common Mistakes and How to Avoid Them

Mistake 1: Calling Regular Citi Customer Service

The number on the back of your credit card connects to Citi's credit card department. They might not be able to help with ThankYou account combining. Use 1-800-THANKYOU instead.

Mistake 2: Not Checking Every Profile Field

People often compare name and address but miss phone numbers. Check every single field. Even blank fields matter—if one account has a home phone and another doesn't, they won't combine.

Mistake 3: Assuming It Won't Work

Some phone agents incorrectly claim you can't combine accounts. This is documented in Citi's own FAQ. If an agent says it's impossible, try calling back and getting someone else.

Mistake 4: Confusing Sharing with Combining

These are different features. Sharing (transferring to another person) is ending May 17, 2026. Combining (merging your own accounts) still works. Be clear about which one you're asking about.

Mistake 5: Canceling Cards Right After Combining

If you combine accounts then cancel a card, the points from that card expire after 60 days. Plan ahead. If you're going to cancel a card, either transfer those points to a partner first or wait to combine accounts until after the cancellation.

What Happens After You Combine

Once you click that combine button and the process completes, here's what changes:

Immediate Changes:

• All your ThankYou points show as one balance
• Each of your cards appears under the same ThankYou member number
• You can transfer points to airline partners from the combined pool
• Point expiration follows the most recent activity on any linked card

What Stays the Same:

• You still have separate credit cards with separate statements
• Card benefits remain tied to specific cards
• Annual fees don't change
• Earning rates on each card stay the same

Going Forward:

• Any new points from any of your ThankYou cards automatically add to the combined balance
• You manage everything through one ThankYou account
• Point transfers to partners pull from the combined total

The Point Sharing Deadline: May 17, 2026

Since Citi announced the end of point sharing, there's been some panic. Here's what you need to know.

What's Actually Ending: The ability to transfer ThankYou points from your account to someone else's account. This affects:

• Couples who were pooling points between separate accounts
• Family members combining points for big redemptions
• Anyone who was using point sharing to help friends or relatives

What's NOT Ending:

• Combining your own ThankYou accounts (the topic of this guide)
• Transferring points to airline and hotel partners
• Earning points on your credit cards
• Your existing point balance

What to Do Before May 17th: If you have a household member with their own ThankYou account and you were planning to share points with them, do it before the deadline. After May 17th, the only way to move points between people is by transferring to an airline/hotel partner, then having them transfer to the other person's loyalty account (where that's allowed).

Troubleshooting Guide

Problem: I don't see my Double Cash account when I log into ThankYou.com

Solution: Log out and log back in selecting your Double Cash as the login card. Then check your profile. One account might not have been linked to ThankYou.com yet, or your profile information doesn't match.

Problem: The combine button appears but gives an error when I click it

Solution: This usually means a backend profile mismatch. Call 1-800-THANKYOU. There's likely a hidden field (like birthdate) that doesn't match between accounts.

Problem: I combined accounts but want to separate them again

Solution: Once combined, accounts can't be separated. This is permanent. If you need separate balances in the future, you'd need to open new ThankYou-earning cards.

Problem: My Custom Cash points show as cash back, not ThankYou points

Solution: When you open a Custom Cash, you choose whether to earn cash back or ThankYou points. If you chose cash back initially, call Citi to switch to ThankYou points, then you can combine that account with your other ThankYou cards.

Problem: I combined accounts, closed a card, and now points disappeared

Solution: Points from a canceled card expire 60 days after closure. If you're within that window, downgrade to a no-annual-fee card or transfer points to a partner immediately.

FAQ

Can I combine ThankYou accounts with my spouse?

No. You can only combine ThankYou accounts that belong to you personally. With point sharing ending May 17, 2026, there's no way to move points between different people's accounts after that date, even household members.

Do I need to have the same address on all my Citi cards to combine accounts?

Yes, your profile information needs to match exactly, including address. If you've recently moved, update all your Citi card addresses first, then combine accounts.

Will combining accounts affect my credit score?

Not at all. Combining ThankYou accounts is just an administrative change in how your points are displayed. It doesn't close accounts, change credit limits, or impact your credit in any way.

Can I still earn points on each card after combining?

Absolutely. Each card continues earning points at its normal rate. Those points automatically add to your combined ThankYou balance. For example, your Citi Premier still earns 3x on travel and dining, while your Citi Rewards+ continues rounding up purchases to the nearest 10 points.

What happens to my points if I cancel one card after combining accounts?

Points earned from that specific card expire 60 days after cancellation. The problem is that once combined, you can't easily tell which points came from which card. This is why downgrading cards instead of canceling them is safer after combining accounts.

How long does it take to combine accounts?

Usually just a few minutes once you click the combine button. Sometimes it can take up to a day for everything to sync, but it's typically instant.

Can I combine more than two accounts at once?

Yes. If you have three, four, or more ThankYou-earning cards, you can combine all of them into a single account at once. This is especially useful if you've been collecting Citi card bonuses across multiple products.

Is there a limit to how many times I can combine or uncombine accounts?

You can only combine accounts once. After that, it's permanent. You can't split them back apart. Think carefully before combining, especially if you're planning to cancel cards soon.

Final Thoughts

Combining Citi ThankYou accounts streamlines your points strategy. Instead of juggling multiple balances, you'll have one clear number showing your total rewards. For most people who plan to keep their ThankYou cards long-term, this makes managing points significantly easier.

The key is getting your profile information to match exactly. That extra space, that missing phone number, that slightly different email address—these small details prevent the combine option from appearing. Fix them, and the process becomes straightforward.

With Citi ending point sharing to other cardholders on May 17, 2026, now's a good time to get your own house in order. Combine your accounts if it makes sense for your strategy, and you'll be ready to maximize those transfer partner opportunities without the hassle of managing multiple point balances.
