Gap accepts payments from card members online through the Gap.com website, over the phone or through the mail. Gap stores do not accept payments for credit card accounts as of April 2015.
Electronic payments on the website allow the Gap card holder to register for an online account. During the process, the user connects the credit card with the online account to access the online payment options. The online payment system requires the user to enter the bank name, routing number and account number. Paying over the phone requires the member to pay a $10 fee as of 2015. Mailed payments go to Gap/SYNCB, PO Box 530942, Atlanta, GA, 30353-0942.
