🔒 Setting or changing the PIN

• During activation (especially online) you’ll typically be asked to choose a 4‑digit PIN.

• If you already have an account and want to change your PIN: log into your account and check the “Manage Card PIN” section (for some Amex products) or call customer service. For example: > “Simply go to the ‘Account’ tab and then select ‘Manage Card PIN’ … Tap ‘Unlock PIN’”

📝 Things to watch / important caveats

• Make sure you are on the official SERVE/American Express website and not a look‑alike.

• Do not share your PIN, full SSN, or sensitive personal info in places you don’t trust.

• Some users report glitches with activation, so if online activation fails, the phone route is a good fallback.

• The card must be activated and your PIN set (if required) before you can use it for purchases or withdraws at ATMs.

• Use secure WiFi when entering your personal info.
