Amex 2/90

What it does

Amex restricts how often you can open new accounts, with TWO limits running at once: at most 1 new credit card every 5 days, and at most 2 in any rolling 90-day window. Charge cards (Platinum, Gold, Green personal + business) are exempt from both, though Amex caps you at 10 charge cards at a time. The 'Pop-up Jail' (a soft-deny modal saying you don't qualify for the bonus) is a separate, stricter behavior driven by other signals - 2/90 and 1/5 are the hard application limits.

How it works

• Only credit cards count: Blue Cash Preferred, Blue Cash Everyday, Hilton Honors, Marriott Bonvoy Brilliant, Delta SkyMiles cards, Business Plus, Business Cash, etc.
• The 1/5 rule runs alongside 2/90: even with both 90-day slots free, a second credit card cannot be approved until 5 days after the first.
• Charge cards do NOT count toward either velocity limit: Personal Platinum, Gold, Green; Business Platinum, Gold, Green. They have their own ceiling - Amex limits you to 10 charge cards at a time, separately from the 5-credit-card holding limit.
• The 90-day window is rolling, not calendar. If you opened a credit card 89 days ago and another 1 day ago, you cannot open a 3rd until day 90 + 1.
• The clock is by application approval date, not application date. A pending or denied application does not consume a slot.

What to do

• Charge cards (Plat + Gold + Green, personal and business) are exempt from both velocity limits, so they are the flexible piece - but stop at 10, which is where Amex caps charge-card holdings.
• When you want credit cards from Amex, take the two 90-day slots five days apart: one card, then a second after 5 days, then wait out the 90-day window before the next pair.
• Watch for "5/24-style" Amex Pop-up Jail when chasing welcome bonuses; it's separate from these limits but feels similar from the user's side.
