A product change (PC) lets you switch your existing credit card to a different card within the same issuer's lineup — for example, upgrading a Chase Freedom Unlimited to a Chase Sapphire Preferred, or downgrading an Amex Platinum to an Amex Green. The key advantage: your credit history, account age, and credit limit transfer to the new card, and there's no hard inquiry on your credit report.

Downgrading preserves your account age (which helps your credit score), maintains your credit limit (improving your utilization ratio), and keeps the relationship with the issuer open. If you have a $695 Amex Platinum but no longer travel enough to justify it, downgrading to the no-fee Amex Green keeps 10+ years of account history intact. Canceling would remove all of that.

Generally no — you cannot earn a sign-up bonus through a product change because you're modifying an existing account, not opening a new one. However, the rules vary by issuer. With Chase, you may be eligible for a new card's bonus if you apply separately (subject to 48-month bonus rules). American Express has a once-per-lifetime bonus rule. If you want the sign-up bonus, apply for a new card instead of product changing.

Chase, American Express, Citi, Bank of America, Capital One, and US Bank all allow product changes between cards in their lineups, though each has different rules. Chase requires you to have held the card for at least one year before upgrading. Amex may offer targeted upgrade offers with bonus incentives. Capital One product changes are limited to specific card families. Our tree maps out all confirmed paths by issuer.

Call the number on the back of your card and ask to 'product change' or 'switch' to the specific card you want. The representative will check your eligibility and process the change. Some issuers (like American Express) also allow product changes through their website or app via targeted upgrade offers. The process typically takes 5-10 minutes and goes into effect immediately.
