When you receive your physical card, you can set a card Personal Identification Number (PIN) for PIN-based transactions, including ATM cash withdrawals. KAST is updating the card PIN flow so that new or updated card PINs must be 4 digits. This article explains how to set or change your card PIN and how to use your PIN.

Tip: Pick a PIN that’s easy for you to remember but hard for others to guess. Avoid obvious numbers like your birthday or repeated digits.
Should I Use a 4-Digit or 6-Digit Card PIN?
KAST now uses 4-digit card PINs for all new card PIN setup and any card PIN updates.
This change improves compatibility with ATMs around the world, as some ATMs only support 4-digit PINs.
Here's what this means for you:
- Existing cards: If your card already has a 6-digit PIN, you don't need to change it. Your current PIN will continue to work.
- Planning to use ATMs worldwide? We recommend changing your PIN to 4 digits, as some ATMs don't accept 6-digit PINs.
- Changing your PIN: If you decide to update your PIN, your new PIN must be 4 digits.
- New cards: All newly issued KAST cards use 4-digit PINs.
Why is KAST moving to a 4-digit PIN?
Certain ATMs, depending on the country or region, only accept 4-digit PINs. KAST’s previous 6-digit card PIN requirement caused ATM declines and blocked cash withdrawals for some users. Moving new and updated card PINs to 4 digits helps reduce these issues and makes PIN-based transactions, including ATM cash withdrawals, more consistent.
What if I forget my PIN or have issues at the ATM?
- If you forget your PIN, you can reset it anytime in the KAST app using the same steps above.
- If an ATM doesn’t accept your PIN, try changing your card PIN in the KAST app. New or updated PINs must be 4 digits.
- If problems continue, contact KAST concierge through the app or website.
