With the Amazon Prime Visa Signature Card, you get 5 cards per Prime account. This means there can be up to 5 cards - all of which have the same membership number, benefits, and points balance - linked to each Prime account.
If you need additional cards for family members, you can call the customer service line and request additional cards for them. The application process applies to the primary cardholder, though, so the primary cardholder needs to collect the required information for each additional cardholder and submit it to customer service.
Amazon Prime Visa Signature Card holders also benefit from a 0% intro APR on purchases and balance transfers for 12 months, a $70 Amazon.com gift card upon approval, and no foreign transaction fees. Customers will also get 3% back at Amazon.com and Whole Foods Market, 2% back at restaurants, gas stations, and drugstores, and 1% back on all other purchases.
