How CardOptimizer Works

📌 What it does

Most Chase credit cards are subject to the 5/24 rule. If you have opened 5 or more personal credit cards (from any issuer) in the past 24 months, Chase is generally observed to decline your application. This includes cards from any bank — not just Chase. Cards are counted based on account opening date, not approval date.

💡 Why it exists

Chase uses the 5/24 rule to limit approvals for applicants who rapidly open multiple cards for signup bonuses. It acts as a velocity control mechanism to reduce bonus abuse and acquisition costs.

✅ How to satisfy

You generally need to be under 5/24 at the time of application. Cards fall off your count exactly 24 months after their opening date. Some business cards (especially from Chase and Amex) typically do not add to your 5/24 count, but they may still require you to be under 5/24 for approval. Authorized user accounts usually appear in your 5/24 count, but can sometimes be removed through reconsideration if you are not financially responsible for the account.

📌 What it does

Current Amex welcome-offer terms are product-specific. Verified Platinum, Gold, Hilton, and Business Delta offers may consider whether you have or have had the named products, including through product changes, and not only prior bonuses.

💡 Why it exists

American Express reserves welcome offers for applicants who meet each target offer's current named-product scope and may also consider account history and other factors at its discretion.

✅ How to satisfy

Check the exact target offer, record every prior product in a product-change lineage, and do not infer a family-wide block. Targeted NLL offers may use different terms.

📌 What it does

American Express generally limits how many revolving credit cards you can hold at the same time. Most cardholders are approved for around five Amex credit cards, although the exact number can vary by profile. Charge cards (such as Platinum, Gold, and Green) are evaluated separately and typically do not count toward this credit card limit because they do not have preset spending limits.

💡 Why it exists

This is an internal risk control policy. Amex manages overall credit exposure by limiting the number of open revolving credit lines rather than strictly limiting the total number of Amex cards.

✅ How to satisfy

If you are denied for 'too many credit cards,' you may need to close an existing Amex credit card or move credit limits between accounts. In many cases, charge cards can still be opened because they are evaluated independently.

📌 What it does

Citi is widely observed to limit how frequently you can be approved for new cards. Most applicants are approved for no more than one Citi card within about 8 days, and no more than two Citi cards within about 65 days. These are not officially published rules, but consistent approval patterns seen across many applications.

💡 Why it exists

Citi uses velocity controls to reduce rapid account openings and manage risk exposure. Rather than a long-term restriction like Chase 5/24, this rule controls short-term application frequency.

✅ How to satisfy

After a Citi approval, it is generally safest to wait at least 8 days before applying again. After two approvals, waiting about 65 days from the most recent approval significantly improves approval odds.

📌 What it does

Many Citi cards appear to restrict welcome bonus eligibility for 48 months after you last received a bonus on that same card. In most current Citi terms, the 48-month clock is based on when you received the previous signup bonus — not when you opened or closed the account. Some Citi card families, particularly ThankYou points cards, may include cross-card language that limits bonuses across related products.

💡 Why it exists

Citi uses a long bonus restriction window to discourage repeat bonus cycling. The 48-month timeframe is one of the longest among major issuers.

✅ How to satisfy

Check the exact bonus eligibility language in the current offer terms. In most cases, you generally need to wait 48 months from when you received your previous bonus on that card before becoming eligible again. Closing the card does not automatically reset the timer unless explicitly stated in the offer terms.

📌 What it does

Bank of America is widely observed to limit how many new personal credit cards you can open within rolling time windows. The widely observed limits are: no more than 2 new BofA personal cards in any 60-day window, no more than 3 in any 12-month window, and no more than 4 in any 24-month window. These are commonly referred to as the 2/3/4 rule.

💡 Why it exists

Bank of America uses these velocity controls to limit rapid account openings and manage credit risk. Unlike Chase 5/24, which counts cards from all issuers, the 2/3/4 rule only counts Bank of America personal cards. These limits are widely observed but not officially published by the bank.

✅ How to satisfy

Space your Bank of America personal card applications to stay within the 2/60, 3/12, and 4/24 windows. Business cards are generally exempt from these limits and do not count toward the personal card caps.

📌 What it does

Discover appears to limit cardholders to a maximum of 2 credit cards at any given time. If you already hold 2 Discover cards, your application for a third is generally expected to be denied until you close one. Additionally, Discover appears to enforce a 12-month cooldown between opening new cards. All Discover card types count toward this limit, including student cards and secured cards.

💡 Why it exists

Discover uses the 2-card cap and 12-month cooldown to manage credit risk exposure per customer. Unlike issuers that restrict based on velocity or total cards across banks, Discover simply limits the number of concurrent products. Because Discover offers Cashback Match (doubling all rewards in the first year), the cooldown also prevents rapid cycling of first-year bonuses.

✅ How to satisfy

To open a new Discover card when you already hold 2, you generally need to close an existing Discover card first. After closing, wait for the account to fully process before reapplying. For the 12-month cooldown, you generally need to wait at least 12 months from the opening date of your most recent Discover card before applying for another.

📌 What it does

For a personal Sapphire card, the exact card is unavailable while you currently have that product open. If you previously held that exact product or received its new cardmember bonus, the bonus may not be available at Chase's discretion. A different personal Sapphire product does not cross-block, and Sapphire Reserve for Business is separate.

💡 Why it exists

Chase now evaluates Sapphire offers by exact product and reserves discretion over repeat-bonus eligibility. That requires separating whether the card itself is available from whether its welcome bonus may be offered.

✅ How to satisfy

Do not apply for the same personal Sapphire product while it is still open. If you previously held the exact target product or received its bonus, review the secure application terms and any eligibility message before submitting. There is no published fixed 48-month family clock.

📌 What it does

Each Amex Hilton card (Honors, Surpass, Aspire, Business) has its own independent per-product lifetime bonus. Hilton cards do not appear to block each other across tiers — there is no observed ascending-order restriction or cross-card blocking. Application order does not appear to determine eligibility. However, standard American Express restrictions still apply: lifetime language on the same product, upgrade history counting as prior ownership, and occasional welcome-offer ineligibility pop-ups.

💡 Why it exists

Unlike Delta or Membership Rewards families, Amex does not appear to enforce a tier hierarchy on Hilton cards. Each Hilton product is treated as a completely separate product with its own independent bonus eligibility. This makes Hilton one of the most straightforward Amex card families for collecting multiple welcome bonuses.

✅ How to satisfy

You can earn a bonus on every Hilton card in any order — Aspire first, then Surpass, then Honors — and earn all bonuses. The only restrictions are: (1) you can only earn each specific card's bonus once (per-product lifetime), (2) upgrading/product-changing to a Hilton card counts as prior ownership (forfeiting its bonus), and (3) Amex may show a pop-up warning that you're ineligible for the welcome offer, which is based on your overall Amex relationship.

📌 What it does

Barclays is observed to allow only one JetBlue personal card at a time — JetBlue Card, JetBlue Plus, or JetBlue Premier. You generally need to close or product-change your current JetBlue personal card before applying for a different one. The JetBlue Business card is separate and does not appear to be affected by this restriction. Additionally, bonus eligibility appears to reset after 24 months.

💡 Why it exists

Barclays enforces a one-personal-card-per-family policy for JetBlue products. This prevents customers from holding multiple tiers simultaneously and encourages product changes rather than new applications. The 24-month bonus cooldown discourages frequent churning.

✅ How to satisfy

If you want a different JetBlue personal card, close or product-change your current one first. For bonus eligibility, wait 24 months from when you last received a JetBlue bonus. The business card can be held alongside any personal JetBlue card.

📌 What it does

Barclays is observed to allow only one Wyndham personal card at a time. You generally need to close or product-change your current Wyndham personal card before applying for a different one. The Wyndham Business card is separate and does not appear to be affected by this restriction. Additionally, bonus eligibility appears to reset after 24 months.

💡 Why it exists

Barclays enforces a one-personal-card-per-family policy for Wyndham products. This prevents customers from holding multiple personal Wyndham tiers simultaneously. The 24-month bonus cooldown discourages frequent churning while still allowing repeat bonuses.

✅ How to satisfy

If you want a different Wyndham personal card, close or product-change your current one first. For bonus eligibility, wait 24 months from when you last received a Wyndham bonus. The business card can be held alongside any personal Wyndham card.

📌 What it does

Personal Delta terms name higher personal tiers, producing a Gold → Platinum → Reserve order. Current Business Delta terms use same-product/previous-version ownership language and do not name other Business Delta tiers. Product changes count as having had the target.

💡 Why it exists

Each target offer defines its own named-product scope, and Amex may also consider account history and other factors at its discretion.

✅ How to satisfy

Preserve Gold → Platinum → Reserve order for personal Delta. Business Delta does not use that ladder under current verified terms; record exact same-product and previous-version ownership.

📌 What it does

Amex personal Membership Rewards cards (Green, Gold, Platinum) appear to follow an ascending-order rule. Opening a higher-tier card first has been observed to block bonuses on lower-tier cards. For example, if you open Platinum first, you would likely lose eligibility for the Gold and Green bonuses. Additionally, upgrading (product-changing) to a higher tier appears to permanently forfeit that card's welcome bonus.

💡 Why it exists

Amex appears to enforce tier ordering to encourage customers to work up through the product lineup rather than cherry-picking the top card. The upgrade trap prevents gaming via product changes — Amex wants new applications for each tier.

✅ How to satisfy

Apply for personal MR cards in ascending order: Green first, then Gold, then Platinum. Never upgrade to a higher MR tier — always apply as a new card. Each tier's bonus appears to be earnable only once per lifetime.

📌 What it does

Amex Blue Cash cards appear to follow an ascending-order rule. Opening Blue Cash Preferred first has been observed to block the Blue Cash Everyday bonus. Additionally, upgrading (product-changing) from Everyday to Preferred appears to permanently forfeit the Preferred welcome bonus.

💡 Why it exists

Amex applies the same tier-ordering restriction to its cashback lineup. Preferred is the higher tier, so opening it first appears to block the Everyday bonus.

✅ How to satisfy

If you want bonuses on both cards, apply for Blue Cash Everyday first, then Blue Cash Preferred. Never upgrade from Everyday to Preferred — apply as a new card to preserve the bonus.

📌 What it does

Amex Marriott Bonvoy consumer cards appear to follow an ascending-order rule. Opening the Brilliant (higher tier) first has been observed to block the Bevy bonus. This is separate from the Marriott cross-issuer rule — even if the cross-issuer cooldown is clear, the ascending-order restriction still applies. Business cards are not affected.

💡 Why it exists

Amex applies tier-ordering restrictions to its Marriott Bonvoy lineup. Brilliant is the premium tier, so opening it first appears to block the Bevy bonus. This prevents customers from cherry-picking the top card and then collecting lower-tier bonuses.

✅ How to satisfy

If you want bonuses on both Amex Marriott consumer cards, apply for Bevy first, then Brilliant. The Marriott Business card is independent and can be applied for in any order.

📌 What it does

Chase United cards use a 24-month welcome bonus cooldown for the same product. If you received a bonus on the same United card within the last 24 months, you are not eligible for that card's welcome bonus. A bonus on a different United product does not block it.

💡 Why it exists

The restriction is product-specific rather than family-wide. Chase tracks the last bonus received on the exact United card, so Explorer, Quest, Club, Gateway, and business products have independent welcome bonus histories.

✅ How to satisfy

Wait 24 months from when you last received a bonus on the same United card. Track the bonus receipt date, not the application or account-opening date.

📌 What it does

Official Chase terms make Plus, Premier, and Priority unavailable if you currently hold any Southwest personal card or received a new-cardmember bonus on any Southwest personal card within the last 24 months. Business and employee cards are excluded. Each Southwest business card instead has a separate 24-month exact-product restriction on its new-cardmember bonus offer.

💡 Why it exists

The written terms use two distinct scopes. The personal restriction governs product availability across the personal family. The business restriction governs only the bonus offer for the exact business product; it does not create a cross-business or personal restriction and does not state that product approval is unavailable. Both 24-month clocks start when the bonus is received.

✅ How to satisfy

For a personal card, you must not currently hold any Southwest personal card and must be at least 24 months past your most recent Southwest personal bonus receipt date. For a business-card bonus offer, you must not currently hold that exact business card and must be at least 24 months past the bonus receipt date for that exact product.

📌 What it does

Under current Chase terms, IHG Premier and IHG Traveler form one personal-card family. Current holders of any IHG personal card cannot obtain either personal product, and a new-cardmember bonus received on any IHG personal card within the prior 24 months restricts both. IHG Business is excluded and separate from this personal-family rule.

💡 Why it exists

The terms use one family-wide scope for the two personal products rather than separate Premier and Traveler clocks. Ownership and bonus receipt are distinct checks, and neither check includes IHG Business.

✅ How to satisfy

You must have no current open IHG personal card and be at least 24 months past the exact date your latest IHG personal new-cardmember bonus was received. The restriction ends on the exact 24-month anniversary. If ownership is uncertain, correct the card status in your wallet; if the bonus date is uncertain, enter the exact posting date. Passing these checks does not guarantee approval or a bonus, so verify the secure application terms.

📌 What it does

Official Chase offer terms make both Prime Visa and Amazon Visa unavailable if you currently have either consumer card. This is a current-holder product-availability rule, not a published 24-month former-holder cooldown.

💡 Why it exists

Both product pages use the same cross-product wording: the card is available only if you do not currently have an Amazon Visa or Prime Visa. Amazon business cards are separate products, and an authorized-user card does not establish that you are the cardmember.

✅ How to satisfy

You must have no open Prime Visa or Amazon Visa account in your own name. Confirm uncertain account statuses in your wallet. Closed former-holder accounts do not trigger this current-holder rule, though Chase still controls final approval and whether a returning customer qualifies as a new cardmember for the gift card.

📌 What it does

Checks prior ownership or bonus history for Ink Cash or Ink Unlimited. Current terms say the bonus may not be available after either no-annual-fee Chase business card; this is issuer discretion, not a fixed cooldown or application denial.

💡 Why it exists

Ink Cash and Ink Unlimited use the same no-annual-fee Chase for Business bonus scope.

✅ How to satisfy

Enter the exact prior Ink product and any product-change lineage. Complete history can still result in issuer review because Chase makes the final bonus decision.

📌 What it does

Current Marriott offer terms use product-specific eligibility matrices, not one universal Chase-vs.-Amex rule. Bold and Boundless share one Chase legacy-consumer scope; Bountiful has a separate exact-product scope; Amex Bonvoy Business, Brilliant, and Bevy each name different prior-card groups. Depending on the target, the terms separately test current product availability, 30-day ownership, 90-day approval or acquisition, and 24-month new-card or upgrade bonuses.

💡 Why it exists

Each offer names its own list of prior Marriott products and its own event type. Ownership, approval or acquisition, new-card bonuses, and upgrade bonuses are not interchangeable. Ritz-Carlton matters for some Amex targets but is not a universal blocker.

✅ How to satisfy

Select the exact target product and verify every clause named in that offer. A result for one Marriott card must not be reused for another.

📌 What it does

Capital One's current personal-card bonus terms use product-specific 48-month scopes. Venture X, VentureOne, Savor, and Quicksilver each check the same product. Venture is the exception: its terms check prior bonuses on either Venture or Venture X.

💡 Why it exists

The written terms do not create one universal Capital One personal-card family. Product identity matters: SavorOne does not block Savor, QuicksilverOne does not block Quicksilver, and VentureOne does not cross-block Venture or Venture X under the current public wording.

✅ How to satisfy

Wait until the exact 48-month anniversary of the relevant bonus receipt. For Venture, check both Venture and Venture X bonus history; for Venture X, VentureOne, Savor, and Quicksilver, check only the exact target product.
