Hi, @scott666! I’m sorry for the inconvenience. While we can’t provide full account numbers online for security purposes, there are a number of ways we can help:
Please call Synchrony’s HSN Card Services at (844) 889-9676 for an HSN Private Label Credit Card or (844) 889-9674 for an HSN Mastercard. You can enter # to bypass the account number enter and reach the first available team member.
You can also contact Synchrony directly through their Facebook (https://www.facebook.com/SynchronyFinancial) or Twitter (http://twitter.com/asksynchrony). If you send your phone number by private message or DM, they’ll call you directly to assist.

SUNDAY, SEP 1-2019… Yeah, the girl I spoke to gave me the wrong address!

You have to go to GOOGLE and type -in : Synchrony HSN

Then scroll down a little bit until you see : Manage Your HSN Credit Card Account – Synchrony

Click on that, and it will take you to the Synchrony site dedicated to our HSN Accounts.

You will have to Register to get in. Have your HSN Credit Card number available as you will have to type that in, in order to successfully Register and get to your Account.
