How do I tell my credit card company I am traveling to Capital One?

Here’s what you need instead of a Capital One travel notification: Domestic customer service number: 1-877-383-4802. International customer service number: 1-800-955-7070 (collect call) Card number or Social Security number: Enter your card number when you call to speak to a representative.
