You can use more than 4 digits if you want a more secure PIN.

EMV (the card standard used by all modern chip/contactless cards) supports PINs between 4-12 digits in length.

I have been wanting to try a 4< digit pin, but I expect payment terminals to go bonkers because they don’t accept it. Have any of you a card pin longer than 4?

Six-digit pin works well for me in European countries - Czechia, Germany, Austria, Spain, Italy.

My girlfriend used a 5-digit PIN for over 10 years in the UK and never had any issues that I can recall.

I’d change mine too except I use the PIN so infrequently (99% contactless now days) I’m worried I’d forget the new one!

Just try and be surprised - no issues.

just don't try to use it in some remote exotic place, 4 places are often hardcoded but you may still be able to withdraw/pay, or not

Mine is eight digits, never tried it outside Canada yet.
