Citibank N.A. Headquarters

If you’re researching Citibank N.A. headquarters for a sales call, a vendor file, account-based prospecting, or just general curiosity, the quick answer is 388 Greenwich Street in New York City but that’s only part of the picture. Citibank, N.A., the chartered national bank behind the Citibank brand, actually has its official regulatory “main office” in Sioux Falls, South Dakota, a detail that most company-lookup pages leave out entirely. This guide breaks down both addresses, explains why they’re different, and covers the practical questions people search alongside “Citibank headquarters” from branch hours to closing an account.

Where Is Citibank’s Headquarters?

Citibank’s executive headquarters the address tied to Citigroup’s corporate leadership, investor relations, and most public-facing business is:

388 Greenwich Street, New York, NY 10013

This is the address you’ll find in Citibank’s own corporate communications, in most press coverage, and in general business directories when people search “citi bank hq” or “citi headquarters nyc.” The building sits in Manhattan’s Tribeca neighborhood, a short distance from Wall Street, and houses Citigroup’s executive offices alongside key Citibank leadership functions.

Citibank N.A.’s Legal Main Office vs. Its New York Headquarters

Here’s where most sources get the story incomplete. Citibank, N.A. isn’t just a brand name it’s a nationally chartered bank, regulated directly by the Office of the Comptroller of the Currency (OCC) under Charter Number 1461. On its official bank charter and in FDIC records, Citibank, N.A.’s legal “main office” is listed at:

5800 S. Corporate Place, Sioux Falls, SD 57108

This isn’t a clerical error or an outdated filing it’s intentional, and it has a history behind it. In the early 1980s, South Dakota removed its usury interest-rate cap to attract national bank charters. Citibank was among the first major banks to relocate its card-issuing operations there as a result, while keeping executive leadership and most public-facing operations in New York. That structure has persisted ever since: Citibank’s own UK Companies House filing (required because the bank operates a registered branch in the UK) explicitly lists Sioux Falls under “company details in the country of incorporation,” confirming this is the bank’s genuine regulatory home, not just a secondary processing center.

Citibank N.A. vs. Citigroup Inc.: Why the Distinction Matters

If you’re doing account research or prospecting common for sales teams compiling company data it’s worth knowing that “Citibank” and “Citigroup” aren’t interchangeable. Citigroup Inc. is the publicly traded parent holding company (NYSE: C). Citibank, N.A. is its chartered U.S. banking subsidiary the entity that actually holds consumer and commercial deposits and operates under a federal bank charter. Most contracts, loan documents, and regulatory filings reference “Citibank, N.A.” specifically rather than “Citigroup,” so getting the entity name right matters for due diligence, procurement paperwork, or compliance research.

How to Find or Contact Citibank’s Headquarters

For general correspondence, media inquiries, or sales outreach aimed at Citigroup’s corporate offices, 388 Greenwich Street is the address to use. Citibank doesn’t maintain a single public phone line for the headquarters building itself; customer-facing contact runs through Citi’s dedicated service lines instead, which route by product type (credit cards, checking and savings, loans, and so on).

If your purpose is account research rather than customer service for example, verifying a company record before a sales outreach sequence or a compliance check the OCC’s and FDIC’s public bank-lookup tools (searchable by charter number or FDIC certificate) are the most authoritative way to confirm current registered addresses, since they’re updated directly from regulatory filings rather than scraped or templated data.

Citibank Hours: Headquarters and Branch Availability

The 388 Greenwich Street building is a corporate office, not a retail branch, so it doesn’t keep public banking hours. If you’re searching “Citibank hours open” because you need an actual branch, keep these points in mind:

• Branch hours vary significantly by location and format; there’s no single national schedule.
• Most branches are closed on Sundays; a limited number offer reduced Saturday hours, often around 9 a.m. to 1 p.m.
• Digital banking, the mobile app, and ATMs are generally available around the clock.
• Live customer service hours differ by product; some credit card support lines operate 24/7, while other services, such as loans or certain account types, follow more standard business hours.

Because hours can change by branch and by holiday, the most reliable way to confirm current hours is Citibank’s own branch locator rather than a general search result.

How to Close a Citibank Account or Credit Card

Closing a Citibank product isn’t complicated, but a few steps help avoid surprises.

To close a Citibank credit card:

1. Pay your balance down to $0 Citibank generally won’t close a card with an outstanding balance.
2. Contact customer service by phone or through secure chat in the Citi mobile app or website, and request the closure directly.
3. Ask for written or email confirmation that the account is closed.
4. Monitor your credit report for a few billing cycles afterward to confirm the closure processed correctly and no further charges are posted.

To close a Citibank checking or savings account:

1. Bring the balance to zero, or withdraw remaining funds, and redirect any linked automatic payments or direct deposits first.
2. Request closure online (for eligible account types), by phone, by mail, or in person at a branch.
3. Get confirmation in writing, and keep it in case of any later dispute about a reactivated or incompletely closed account.

A couple of things worth weighing before closing either product: closing a long-held credit card can affect your credit utilization ratio and average account age, which may temporarily lower your credit score. If your main concern is avoiding fees or overspending rather than ending the relationship entirely, asking Citibank for a credit limit reduction is a less disruptive alternative to full closure.
