AT&T has partnered with retailers nationwide—including Costco, Best Buy, and Target—to offer joint promotions and in-store and online deals. To better support these important partnerships, AT&T uses dedicated phone numbers, such as 833-603-3321. These numbers are assigned specifically to certain dedicated retailers to provide better local support and give credit to these retailers.
Rest assured, they are official AT&T phone numbers, which connect you directly to authorized AT&T representatives. The retailer-specific numbers are just used to properly track orders, promotions, and support requests for each partner. It also ensures customers receive accurate pricing, promotions, and services related to that retailer’s specific offers.
If you have questions about an order placed through a specific retailer, the number provided with the offer is typically the best way to receive assistance.
For wireless support, however, you can always contact AT&T directly at 800-331-0500 or dial 611 from your AT&T mobile device.
