KYC documents are the identification records a bank collects to verify who you are before opening an account, and federal rules require the bank to gather four things from an individual customer: your full legal name, date of birth, residential or business street address, and a taxpayer identification number.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks To confirm those four data points, you’ll typically be asked for an unexpired government-issued photo ID, a recent document proving your address, and your Social Security Number or equivalent. Business accounts and accounts for non-U.S. persons require additional paperwork on top of that baseline.
Government-Issued Photo Identification
Federal regulations require banks to verify your identity using unexpired, government-issued identification that shows your nationality or residence and includes a photograph or similar safeguard. The regulation specifically mentions driver’s licenses and passports as examples.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks Commonly accepted documents include:
- A state-issued driver’s license or ID card, the most widely used form of identification for domestic account openings.
- A U.S. passport or passport card, which serves as proof of both identity and citizenship.
- A military identification card issued by the Department of Defense, which bears a photograph and meets the regulation’s general criteria.
- A permanent resident card (green card), accepted as government-issued identification showing residence status.
Every document you present must be unexpired at the time you open the account.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks If it has been altered, damaged, or lacks standard security features, the bank can reject it and ask for a replacement.
Mobile Driver’s Licenses
Several states now issue mobile driver’s licenses (mDLs) that store your ID digitally on a smartphone. An international standard (ISO/IEC 18013-5) has been published to support global deployment of these credentials, and implementation guidelines continue to be updated. Acceptance at financial institutions varies widely, though, and no federal regulation currently requires banks to accept digital-only identification. If you plan to use a mobile ID, confirm with the institution beforehand that it will be accepted.
Proof of Address
The federal rule requires the bank to collect your street address, but it doesn’t dictate which document must confirm it. In practice, most banks ask for a separate document linking your name to a physical location. Commonly accepted proof-of-address documents include:
- Utility bills from water, gas, electric, or internet service providers showing your name and service address.
- Bank or credit card statements from another financial institution displaying your current address.
- Lease agreements or mortgage statements showing your name as a tenant or homeowner at a specific property.
- Property tax receipts tying your name to a residential address.
- Voter registration cards or insurance documents as alternatives if you lack the items above.
Most banks want proof of address dated within the past 60 to 90 days, though that window comes from bank policy rather than a specific federal rule. A P.O. box alone does not satisfy the address requirement for individuals who have a street address, though military APO/FPO addresses are accepted. If your address has changed recently and your ID and proof-of-address document don’t match, expect a request for additional documentation or a manual review.
Taxpayer ID and Financial Background
A taxpayer identification number is one of the four mandatory data points. For most U.S. individuals, this means a Social Security Number. If you aren’t eligible for an SSN, you can use an Individual Taxpayer Identification Number (ITIN). The IRS uses these numbers for tax administration, and banks need them to report interest income and comply with backup withholding rules.2Internal Revenue Service. Taxpayer Identification Numbers (TIN)
Beyond the taxpayer ID, many banks also ask for financial background information to assess risk. That often includes your current employment status and employer name, the expected types and volume of transactions in the account, and the anticipated source of deposits. For higher-risk accounts or larger balances, the bank may request documentation explaining how you earned or accumulated your wealth, such as tax returns, pay stubs, or investment account statements. These questions build a risk profile the bank uses to flag unusual activity later.
Additional Documents for Business Accounts
Opening a business account involves everything required for an individual plus documentation about the entity itself. FinCEN’s Customer Due Diligence Rule requires banks to identify and verify the beneficial owners of any legal entity customer, meaning both the individuals who own 25 percent or more of the entity and at least one individual who has significant control over its management or operations.3Federal Register. Customer Due Diligence Requirements for Financial Institutions
Typical documents requested for a business account:
- Formation documents, such as articles of incorporation for corporations, articles of organization for LLCs, or partnership agreements for partnerships.
- An Employer Identification Number (EIN), the federal tax ID assigned by the IRS to businesses. You can use your EIN immediately after receiving it, including for opening a bank account.4Internal Revenue Service. Employer Identification Number
- A beneficial ownership certification form identifying every individual who owns 25 percent or more of the entity and the person with primary management responsibility, including their names, dates of birth, addresses, and identification numbers.
- Government-issued photo ID for each beneficial owner, subject to the same identification requirements that apply to individual accounts.
The bank verifies each beneficial owner’s identity using the same procedures it uses for individual customers. Photocopies of identification documents are permitted for this purpose, unlike the original-document policies some banks apply for primary account holders.3Federal Register. Customer Due Diligence Requirements for Financial Institutions
Documents for Non-U.S. Persons
Non-U.S. citizens and nonresident aliens can open accounts at U.S. financial institutions, but the identification options differ. In place of an SSN, the federal regulation allows a non-U.S. person to satisfy the identification number requirement with a passport number and country of issuance, an alien identification card number, or the number from another government-issued document showing nationality or residence that includes a photograph.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks Some banks also accept permanent resident cards, employment authorization cards, and consular identification cards from certain countries.
Non-U.S. persons who receive income from U.S. sources, such as interest on a bank account, typically need to submit IRS Form W-8BEN. The form establishes that you are not a U.S. person and, if applicable, lets you claim a reduced withholding rate under an income tax treaty between the United States and your home country. Without a valid W-8BEN on file, the bank may withhold 30 percent of certain payments or apply the 24 percent backup withholding rate.5Internal Revenue Service. Instructions for Form W-8BEN
How the Bank Uses Your Documents
Once you submit everything, the bank’s compliance team verifies your identity using one or both of two methods set out in the regulation.6eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
Documentary verification is the standard route when you apply in person. The bank reviews the government-issued photo ID you provided and confirms it is unexpired, appears genuine, and matches the information on your application. For business accounts, the bank also reviews formation documents and other entity records.
Non-documentary verification comes into play when you open an account online, by mail, or when documents alone aren’t enough. The bank may compare the information you provided against consumer reporting agency records, public databases, or other third-party sources. It may also contact you directly, check references with other financial institutions, or request a financial statement.6eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks Banks are also required to check your information against government watchlists, including lists of known or suspected terrorists.
Processing times vary. Online applications with clean data can clear within a day; flagged applications or manual reviews can take several business days. If the automated system spots a discrepancy, such as a name mismatch between your ID and a credit database, you’ll usually get a request for clarification or extra documents before the account can be activated.
If Verification Fails or You Provide False Information
When a bank cannot verify your identity to its satisfaction, the most common outcome is that it refuses to open the account. For existing accounts where identity later comes into question, the bank may restrict functionality by limiting deposits, withdrawals, or transfers until the issue is resolved. In some cases, the bank closes the account entirely.
Intentionally providing false information during the KYC process can bring criminal charges. Under federal law, making a false statement to a financial institution is punishable by up to five years in prison.7Office of the Law Revision Counsel. 18 U.S. Code 1001 – Statements or Entries Generally If the false information is part of a scheme to defraud a bank, the penalties climb sharply: bank fraud carries a maximum fine of $1,000,000 and up to 30 years in prison.8Office of the Law Revision Counsel. 18 U.S. Code 1344 – Bank Fraud Even honest errors on your application can delay account opening and trigger extra scrutiny, so check every detail before submitting your documents.
