Manage Your GTCC Account

Start Here If You Are New to CitiManager

Your GTCC account lives in CitiManager, Citi's self-service portal for cardholders. Use the web at https://home.cards.citidirect.com/ or the mobile app on the App Store and Google Play. View your statement, current balance, payment history, and pending charges. Pay your bill (split disbursement covers most of it but you handle any shortfall). Sign up for paperless statements and account alerts. If you applied for a GTCC after March 2020, your CitiManager account was auto-enrolled by Citi during card issuance. Older accounts require self-enrollment. Citi customer service is available 24/7 at 1-800-200-7056. Per DoDI 5154.31DoDI 5154.31 Vol 4 and the CitiManager Digital Reference Guide.

Paperless statements are encouraged but optional.

Why Paperless

• No paper to lose or forward during PCS.
• Cleaner electronic recordkeeping for travel claim reconciliation.

How to Enroll

1. Log in to CitiManager.
2. Navigate to Account Settings > Statement Delivery Preferences.
3. Select Paperless.

Account Alerts

Alerts notify the cardholder of account events in real time.

Common Alert Types

• Transaction posting (any charge over a threshold).
• Payment due reminder (typically 5 days before due date).
