Question 4

Why does OPTUM BANK, INC. have multiple routing numbers?

Accepted Answer

Large US banks like OPTUM BANK, INC. often have multiple ABA routing numbers — typically one per state or region. This is because the routing number system was originally designed for a geographically segmented banking network where each bank operated primarily within a single Federal Reserve district. When banks expanded nationally, they retained separate routing numbers per state. The correct routing number for your OPTUM BANK, INC. account depends on the state where your account was originally opened — not necessarily where you live today.

Question 5

What happens if I use the wrong OPTUM BANK, INC. routing number?

Accepted Answer

Using the wrong routing number on an ACH transfer or direct deposit will cause the transaction to be rejected and returned — typically within 1–3 business days. The funds are returned to the originating account. For wire transfers, a wrong routing number may delay settlement or route the wire to an incorrect institution, requiring a recall process. Always verify the correct OPTUM BANK, INC. routing number for your specific state using BankZop before submitting any payment or setting up direct deposit.

Question 6

Where is the OPTUM BANK, INC. routing number printed on a check?

Accepted Answer

The OPTUM BANK, INC. routing number is printed at the bottom-left of every personal check in the MICR line — the band of magnetic ink characters at the very bottom of the check. It is always the first 9-digit sequence, surrounded by transit symbols that look like colons. The account number appears in the center of the MICR line, and the check number appears on the right. Do not confuse the routing number (9 digits, always first) with the account number (varies in length, appears second).

Question 7

Is the OPTUM BANK, INC. routing number the same for all accounts?

Accepted Answer

Not always. OPTUM BANK, INC. may use different routing numbers for accounts opened in different states. Two customers of OPTUM BANK, INC. — one in California and one in New York — may have different routing numbers even though they bank with the same institution. The routing number assigned to your account depends on the state where it was opened. Use BankZop to select your state and find the correct OPTUM BANK, INC. routing number for your account.

Question 8

Can I use the OPTUM BANK, INC. routing number for international transfers?

Accepted Answer

No. ABA routing numbers like OPTUM BANK, INC.'s only work within the US domestic payment system (ACH, Fedwire). For international wire transfers to or from a OPTUM BANK, INC. account, you need the bank's SWIFT/BIC code — not the 9-digit routing number. Visit BankZop's SWIFT Code Lookup to find the correct SWIFT code for international transfers. Your receiving bank abroad will also typically require your full account number and OPTUM BANK, INC.'s SWIFT code.
