How to Open a US Bank Account Without a Social Security Number
Many newcomers assume a Social Security Number (SSN) is mandatory to open a US bank account — and many banks act as if it were. In fact, no federal law requires an SSN. The real obstacle is banks' internal policies, which vary widely and change often. This guide explains what the law requires, how the ITIN route works, and which banks tend to accommodate applicants without an SSN.
The federal rule: no SSN is required by law
Under Section 326 of the USA PATRIOT Act, every US bank must run a Customer Identification Program (CIP) (31 CFR 1020.220). Before opening an account, the bank must collect your name, date of birth, address, and an identification number.
What counts as that identification number is the key detail. For a US person it is a taxpayer identification number (typically the SSN). For a non-US person, the rule gives four alternatives:
| Acceptable identification number (non-US persons) | Notes |
|---|---|
| A taxpayer identification number | ITIN, EIN, or SSN if you have one |
| Passport number and country of issuance | The most common option for newcomers |
| Alien identification card number | E.g., green card or employment authorization card number |
| Another government-issued photo ID number | E.g., home-country driver's licence, if accepted |
So when a bank teller says an SSN or ITIN is "required by federal law," that's not accurate: the federal requirement is an identification number, and a passport number plus country of issuance satisfies it. When a bank insists anyway, that is the bank's own policy — driven by its systems, compliance, or tax-reporting needs — not a federal mandate.
This distinction matters: the real negotiation is not with the law, but with the bank's procedures and the staff at the branch you visit.
The ITIN route: when it helps and how to get one
The Individual Taxpayer Identification Number (ITIN) is a 9-digit tax number issued by the IRS for people who need a US tax ID but cannot get an SSN — foreign nationals, certain residents, and spouses or dependents of US taxpayers, among others.
An ITIN makes account opening much easier, because banks' systems are built around numeric tax IDs. You apply with IRS Form W-7, usually attached to a federal tax return (Form 1040 or 1040-NR) plus original or certified identity documents — most applicants use their passport. Certain applicants qualify under an exception category and can apply without a tax return.
- Processing time: about 7 weeks normally; 9–11 weeks during tax season (January 15–April 30) or when applying from overseas, per IRS guidance.
- How to submit: by mail to the IRS Austin Service Center, or in person at an IRS Taxpayer Assistance Center, a VITA site, or through an Acceptance Agent who can certify your documents so you keep your original passport.
- One critical limitation: the IRS is explicit that an ITIN is for federal tax purposes only — not identification outside the tax system, not work authorization, and not a substitute for a government-issued photo ID. You still need your passport at the branch, ITIN or not.
Apply for the ITIN early if you will need one for a US tax return anyway. But do not wait for the ITIN to start the account-opening process — many applicants open accounts before their ITIN letter arrives.
Which banks accommodate non-SSN applicants
Policies change frequently and vary by branch, so treat this as a starting point and confirm with the bank before applying. Online applications at most banks require an SSN — expect a branch visit.
| Bank | What is reported as possible (2025–2026) |
|---|---|
| Bank of America | A documented ITIN path for non-permanent residents; accepts foreign tax ID numbers. Generally requires a branch visit for ITIN accounts. |
| Chase | Reported to accept an ITIN in place of an SSN for checking and savings accounts. |
| Wells Fargo | Reported to accept an ITIN in place of an SSN; reportedly allows online checking applications with an ITIN. |
| Citibank | Reported to accept an ITIN in place of an SSN. |
Practical notes:
- Branch staff knowledge varies — the person at the counter may not know the bank's ITIN procedure even when it exists. Ask for the branch manager or the new-accounts desk, and bring printed policy references if you have them.
- Without an SSN or ITIN on file, expect a non-interest-bearing checking account. Banks steer these applicants to basic checking, since interest-bearing accounts trigger tax reporting the bank cannot easily do without a tax ID.
- Complete Form W-8BEN (Certificate of Foreign Status) to certify you are not a US person for tax purposes — this lets the bank handle tax reporting correctly without a US tax ID, for example applying the correct withholding on interest.
What to bring to the branch
Success at the branch is mostly about documentation. Bring originals (and photocopies) of:
- Unexpired passport, with your US visa if you have one
- A second government-issued photo ID — your home-country driver's licence or a consular ID card
- Proof of a US address — a signed lease, utility bill, or official mail showing your name and address
- ITIN assignment letter (CP565 notice) if you already have one
- Immigration documents — your I-94 record, visa, or Employment Authorization Document (EAD) if applicable
If your passport is your primary ID and you have no ITIN yet, say so plainly and ask for the bank's non-resident or ITIN onboarding process. Organized documents signal preparation, which helps the staffer invest the effort an unusual application needs.
The no-address problem: a reality check for new arrivals
The hardest case is the newcomer with no US address yet. Most banks require proof of a US residential address, and this — more than the missing SSN — blocks many applications. A hotel address or P.O. box is generally not accepted.
Sequence it right: visit the branch after you have a lease or other address documentation. If you are arriving soon, some newcomers use an employer or relative's address, though the bank will want documentation linking you to it. Do not pay third-party services promising a "bank-ready US address" — banks treat those as red flags, and some arrangements risk violating the bank's terms.
Business accounts in one paragraph
For a US business, the route is different and often easier. A US LLC can obtain a federal Employer Identification Number (EIN) from the IRS without an SSN, and business-focused fintechs such as Mercury and Relay typically accept an EIN with remote onboarding and no SSN from founders. Traditional banks still tend to want in-person visits and personal ID from signers, so fintechs are the path of least resistance for non-resident founders.
Frequently asked questions
Is it illegal for a bank to ask for my SSN?
No. Banks must collect an identification number under the CIP rule, and nothing stops a bank from requiring an SSN or ITIN as its own policy. The law permits banks to accept a passport number instead — but does not force them to. If one bank refuses, try another.
Can I open an account from outside the US?
For most traditional banks, no — you must appear at a branch in person. A few fintechs offer remote onboarding, particularly for business accounts opened with an EIN. Be cautious of any service promising a full US checking account with no identity verification at all.
ITIN vs. SSN — what's the difference for banking?
Both satisfy the "taxpayer identification number" requirement. The difference is scope: an SSN is also a lifetime identity number and proof of work authorization, while an ITIN is only for federal tax purposes and has no validity as identification outside the tax system. In practice, many banks treat an ITIN as an acceptable SSN substitute.
How long does it take to get an ITIN?
Roughly 7 weeks normally; 9–11 weeks during tax season (January 15–April 30) or when applying from overseas. Apply well ahead of any deadline that depends on it, and start your bank-account process in parallel rather than waiting.
Do I need the ITIN before I can open the account?
Not necessarily. Many banks will open a basic non-interest-bearing checking account using your passport as identification, and you can add the ITIN later. The ITIN makes the process smoother and opens more account types, but it is not always a prerequisite.
