Unable to Verify Date of Birth

Thanks for reaching out @user_w3rxo8! I can understand how frustrating this is, especially after just moving and trying to get internet set up as quickly as possible. This sounds like an identity verification error during new customer account setup.

You’ve already tried the right basic steps by using different browsers, clearing cache, and confirming the MM/DD/YYYY format. Since the error is still happening, we’ll need to review the pending order/account setup details and service address to see what’s preventing verification from completing. Similar verification errors often require account-level review rather than repeating the self-service flow.

Please send us a direct message with your full name and complete service address to “Xfinity Support”. To do so, click on the direct messaging icon located at the top right of this forums page.

Here's the detailed steps to direct message us:

1. Click "Sign In" if necessary.
2. Click the "Direct Messaging" icon.
3. Click the "Start new conversation" (pencil and paper) icon. 
4. In the "To:" line, type "Xfinity Support".
5. As you type, a drop-down list will appear. Select "Xfinity Support" from that list.
6. An "Xfinity Support" graphic will replace the "To:" line.
7. Type your message in the text area near the bottom of the window.
8. Press Enter to send it.

I have the exact same issue!!
in your steps you mentioned Click the "Direct Messaging" icon. Where is this? I don't see it when I'm signed in.

Same thing. When I try to purchase a plan, it says "Unable to Verify Date of Birth." After several attempts, it redirects me to an error page. No "Direct Messaging" icon either.
