More about Citibank

Citibank uses different routing numbers based on the state where you originally opened your account. Using the correct routing number is critical for ACH transfers, direct deposits, and electronic bill payments. Here are all Citibank routing numbers organized by region:

Northeast Region:

Southern Region:

Midwest Region:

Western Region:

Note: If you opened your account in a state not listed above, or if you're unsure which routing number to use, call Citibank customer service at 1-800-374-9700. Using the wrong routing number can delay your payment or cause it to be rejected entirely.

Important: For all domestic wire transfers regardless of your state, use routing number 321171184. For international wire transfers, you'll need SWIFT code CITIUS33XXX instead of a routing number.

Get it right the first time

A wrong number can bounce a transfer or send it into limbo. Two minutes here saves a week of waiting.

Avoid the common mistakes
  • Picking the wrong state — Citibank routing numbers are regional
  • Using the wire number for an ACH transfer (or vice-versa)
  • Transposing a digit; always copy, don’t retype
  • Forgetting the SWIFT code on incoming international wires
Keep transfers secure
  • Routing numbers are public — your account number is what to protect
  • Only share account details over channels you initiated
  • Verify new payees by phone before the first transfer
  • Watch for invoice-swap scams that change banking details
