Activate Your new Card

When you receive your Citi™ MasterCard® card, it can't be used until YOU activate it. Contact Citi MasterCard Customer Care to confirm you've received your new card and we'll verify that it's in the right hands by asking a few simple questions. Your card is then immediately activated and ready for use!

You'll find the correct phone number to call on a sticker on your new card or simply call
1-888-395-7037.

The sooner you activate your Citi MasterCard card, the sooner you'll be able to enjoy the exceptional benefits and services that come with Cardmembership.
