Card issuers have strict rules about who can be approved — and more importantly, who can earn a sign-up bonus. Knowing these before you apply can save you from hard credit inquiries that go nowhere and bonuses you can't earn.
Chase: The 5/24 Rule
Chase will automatically deny most of their cards if you've opened 5 or more credit cards from any issuer in the past 24 months. This is enforced strictly and is one of the most important rules to understand before building a points strategy.
Key nuances:
- Counts ALL personal credit cards from any issuer — not just Chase cards
- Store cards (Target, Amazon, etc.) count if they appear on your credit report
- Business cards from Amex, Chase, Citi, and Barclays typically don't appear on personal credit reports and don't count toward 5/24
- Being an authorized user on someone else's card can count — you may need to request removal from the account
Chase: The Sapphire 48-Month Rule
You cannot earn a new Sapphire bonus (Preferred or Reserve) if you received a Sapphire bonus in the past 48 months. The clock runs from the date the bonus posted to your account, not the application date. The Preferred and Reserve share the same 48-month counter — receiving a Preferred bonus resets the clock for the Reserve too.
American Express: The Lifetime Bonus Rule
Amex will only give you a welcome bonus on a specific card once per lifetime. If you got the Amex Gold bonus in 2018, you're not eligible for another Gold bonus — even if you cancelled the card and reapplied years later.
Amex has improved transparency here: they now show a message during the application process telling you whether you're eligible for the welcome offer. Read this carefully before submitting an application — a hard inquiry with no bonus is a bad outcome.
Chase: The 2/30 and 1/30 Rules
Beyond 5/24, Chase applies additional velocity limits:
- 2/30: Chase will typically deny an application if you've already opened 2 Chase cards in the past 30 days
- 1/30: For Sapphire products specifically, only one application per 30 days
In practice: don't apply for more than one Chase card at a time, and space applications by at least 30–90 days.
Citi: The 24/48-Month Family Rule
Citi restricts bonuses within card "families." You generally cannot earn a bonus on a Citi card if you've opened or closed a card in the same product family within the past 24 months (some premium cards use 48 months). This is product-specific rather than a blanket rule — research before applying for any Citi card.
Amex: The 4-Card Limit and 2-in-90-Days Rule
Amex typically limits personal cardholders to 4 personal credit cards at one time (charge cards are separate). They also tend to deny applications if you've opened 2+ Amex cards in the past 90 days. Amex is more generous than Chase overall — no blanket 5/24-style rule — but they monitor velocity.
The Universal Rules
- Hard inquiries matter: Each application typically results in a hard pull on your credit. Multiple applications in a short window can temporarily lower your score by 5–15 points. Plan applications strategically.
- Minimum credit score: Premium travel cards generally require good-to-excellent credit (700+ FICO). Check your score before applying.
- Space applications 90+ days apart as a general rule unless you've done specific research on what's allowed.
