A Personal Identification Number (PIN) is required to process Link Card transactions. The customer selects their own PIN after they get their Link Card by contacting the Illinois Link Help Line or going to the Link Card website.
The customer can also select a PIN from the Family Community Resource Center (FCRC) using a PIN pad. The FCRC should allow the customer to select a PIN when the customer has been issued a language barrier, is elderly, or is unable to use the phone system or website to select their PIN.
The PIN may be changed at any time after initial issuance. It is not required to change a PIN when replacing a Link Card, although the customer may wish do so if there is a possibility their PIN has been compromised.

A PIN must be selected at the FCRC when there is no SSN identified with the case. A Pin can also be selected at the FCRC when a vault card is issued by the FCRC.
