A customer information form, usually called a CIF, is the identity profile a bank or credit union builds for you when you open an account. Federal law — specifically Section 326 of the USA PATRIOT Act — requires every regulated financial institution to verify who you are before activating the account, and the form is how they collect what they need.1Federal Register. Customer Identification Programs, Anti-Money Laundering Programs, and Beneficial Ownership The form itself might be a paper document at a branch or a series of screens in an online application. The underlying information is largely the same either way, because federal regulations set the floor.
Information You Have to Provide
Under 31 CFR 1020.220, a bank must collect four pieces of identifying information from every individual customer: your legal name, your date of birth, your address, and an identification number. For U.S. persons, that identification number is a taxpayer identification number, which in most cases means your Social Security number. Your address has to be a residential or business street address. A P.O. Box alone isn’t enough, unless you have no fixed address — in that case the bank can accept an Army Post Office or Fleet Post Office box, or the address of a next of kin or other contact.2eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
Most banks ask for more than the four required items. Expect questions about your employment status, your source of income, and the kind of activity you anticipate on the account. These extras aren’t federally mandated line items, but banks use them for their own risk assessments under the Bank Secrecy Act’s anti-money-laundering framework.3FinCEN.gov. The Bank Secrecy Act Answer them straightforwardly; vague or inconsistent answers can slow the review.
Documents to Bring
You need to back up the form with documentation. A government-issued photo ID is the standard starting point — a driver’s license, state ID card, U.S. passport, permanent resident card, or military ID. Many banks ask for a second form of ID drawn from a broader pool, which can include an ATM or credit card, an employee ID, a student ID, or a signed Social Security card.4Wells Fargo. What You’ll Need to Open an Everyday Checking Account If neither ID shows your current physical address, bring a recent utility bill or a similar document that does.
Every detail on the form has to match your supporting documents. If your driver’s license still shows your maiden name and you’ve changed it since, the mismatch will stall your application. Discrepancies between the form and the documents are the most common reason banks delay or kick back an account opening.
If You’re Not a U.S. Citizen
You don’t need a Social Security number to open a U.S. bank account. The CIP regulations let banks accept alternative identification numbers from non-U.S. persons: a passport number together with the country of issuance, an alien identification card number, or the number from any other government-issued document that shows nationality or residence and includes a photograph.2eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks Some banks also accept an Individual Taxpayer Identification Number (ITIN) in that field.5Bank of America. How to Open a Bank Account as an International Professional
Acceptable primary IDs for non-citizens typically include a foreign passport, a U.S. nonimmigrant visa, or certain consular identification cards from countries such as Mexico, Guatemala, Colombia, and the Dominican Republic. A secondary ID — often a foreign or U.S. driver’s license, or a major debit or credit card — is usually required as well.5Bank of America. How to Open a Bank Account as an International Professional You’ll generally need to provide proof of both a foreign address and a U.S. physical address. Call ahead; the specific list varies by institution.
If the Account Is for a Minor
Minors generally have to open accounts at a branch, not online. At many banks, anyone under 18 must be accompanied by an adult co-owner who is a relative or guardian. The adult presents full identification. The minor can present a birth certificate, Social Security card, or student ID if they don’t yet have a government-issued photo ID.4Wells Fargo. What You’ll Need to Open an Everyday Checking Account Both the minor and the adult co-owner go into the bank’s system.
Filling Out and Submitting the Form
On a paper form, print clearly in ink. Confirm that your name, address, and date of birth match the documents you’re about to hand over, because the representative will compare them side by side. Online applications walk you through the same fields on consecutive screens and usually close with an electronic signature and a confirmation page before the data goes through encrypted channels.
If you can’t visit a branch and can’t complete the process online, some banks accept a completed packet by mail. Send it via certified mail with a return receipt so you have proof of delivery. Include clear photocopies of your IDs, not originals, unless the bank’s instructions say otherwise.
Accuracy matters for more than processing speed. Knowingly using false information to defraud a bank is a federal crime under 18 U.S.C. § 1344, carrying fines up to $1,000,000 or up to 30 years in prison.6Office of the Law Revision Counsel. 18 USC 1344 – Bank Fraud The statute reaches schemes to defraud a financial institution by false pretenses, which covers fabricating identity information to open an account.
What the Bank Does With Your Form
Your submission doesn’t just get filed. The bank runs several checks before activating the account.
- Identity verification. The bank compares what you entered against your documents and may also use non-documentary methods such as credit bureau records or other third-party databases to confirm you are who you say you are.7FFIEC BSA/AML InfoBase. Customer Identification Program Examination and Testing Procedures
- Sanctions screening. Banks compare new accounts against the Office of Foreign Assets Control (OFAC) Specially Designated Nationals list before or shortly after opening. Until that check clears, the bank may block all transactions except the initial deposit.8FFIEC BSA/AML InfoBase. Office of Foreign Assets Control
- Terrorist watchlist check. Section 326 of the USA PATRIOT Act separately requires banks to check applicants against government-provided lists of known or suspected terrorists.1Federal Register. Customer Identification Programs, Anti-Money Laundering Programs, and Beneficial Ownership
If everything checks out, the account is often active within one to three business days, and sometimes the same day for in-person applications. If the bank can’t verify your identity, the regulations require it to have procedures for deciding whether to deny the account, allow limited access while verification continues, close the account, or file a Suspicious Activity Report.2eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks In practice, the bank will usually contact you for additional documentation before taking any of those steps.
When to Update Your CIF
Your CIF isn’t a one-time document. A legal name change — from marriage, divorce, or a court order — requires a new form plus supporting evidence such as a marriage certificate or court decree and a government-issued ID in the new name. Some banks also ask you to complete a new IRS W-9 with a handwritten signature.9Capital One. How to Change the Name on Your Account An address change matters too, since the bank mails tax documents and account statements to the address on file. Update it through the bank’s online portal or by phone soon after moving.
Federal rules don’t require banks to re-verify your information on a fixed schedule. The FFIEC examination manual describes ongoing monitoring as “event-driven” — it happens through normal account monitoring, not on a preset timetable. If the bank notices something that doesn’t fit your profile, such as a sudden spike in volume or activity in a country unrelated to your history, it may reach out to update your records. Some banks build voluntary periodic reviews into their own policies, but that’s an institutional choice, not a federal mandate.10FFIEC BSA/AML InfoBase. Assessing Compliance with BSA Regulatory Requirements Ignoring a bank’s request to update your information can lead to a frozen or closed account.
If the Account Is for a Business Entity
Opening an account for an LLC, corporation, or similar entity involves a longer version of this process. In addition to the entity’s legal name and taxpayer identification number, the bank collects public registration documents and the company’s registration ID. The institution also checks the entity’s owners and directors against sanctions lists and databases of politically exposed persons.
Under the Customer Due Diligence Rule, banks have long been required to identify any individual who owns 25 percent or more of a legal entity, plus anyone who controls it.11FinCEN.gov. Information on Complying with the Customer Due Diligence (CDD) Final Rule A February 2026 FinCEN order (FIN-2026-R001) narrowed when that beneficial-owner verification has to happen: when a legal entity first opens an account, when new facts call previously obtained ownership information into question, or as the bank’s own risk-based procedures require.12FinCEN.gov. FinCEN Issues Exceptive Relief to Streamline Customer Due Diligence Requirements Banks no longer have to re-verify beneficial owners every time an existing entity customer opens a new account.
