Why Does Wise Ask for Your SSN in the US?

Financial institutions in the United States require an SSN to verify customer identity. This is a standard procedure driven by federal law. The government requires financial service providers to know who is using their services to prevent financial crime.

For individuals operating in the US, the SSN or a relevant tax ID is the most reliable identifier for this verification process. It ensures that all financial activities are secure and compliant.

It’s a secure, one-time only verification process that Wise must do as part of how they’re regulated in the US. Wise does not run a credit check or share your number during this process.

If your SSN or ITIN isn't accepted, you'll also have an option to verify yourself with an ID and your selfie. US Military IDs aren’t accepted.²

If you’re not a US citizen, you'll be asked for your non-US ID.

Verifying your account is a crucial step for managing your international finances. It provides access to the full suite of tools designed for sending, spending, and receiving money globally. A verified account ensures your payments proceed without delays caused by compliance checks.

This allows you to use the Wise Account to hold and exchange multiple currencies, perfect for travel or managing funds abroad. You can also use the Wise Multi-Currency Card for expenses in other countries. Verification enables seamless international transfers, helping you send money to family or receive funds efficiently.

What US Regulations Require Your SSN?

Wise is required to ask for your SSN to comply with US federal laws designed to combat financial crime. Key regulations include the Bank Secrecy Act (BSA). This law sets the foundation for financial transparency.

The BSA mandates that financial institutions follow Know Your Customer (KYC) and Anti-Money Laundering (AML) rules. These rules require verification of a customer’s identity. The SSN is the primary identifier used in the US for this purpose. Adherence is mandatory to operate legally. Complying with these rules is mandatory, but it’s also the smart way to ensure the entire financial system—and your money—stays secure.

How Does Wise Protect Your SSN?

We know your SSN is sensitive, and keeping it safe is our top priority. Your SSN is safeguarded with robust security measures, including industry-standard data encryption for all information in transit and at rest.

Strict internal policies and access controls ensure that only authorized personnel can view your information for verification purposes. All data is handled in compliance with financial industry data protection standards to maintain security and confidentiality.

When Might Wise Ask for Your SSN?

The request for an SSN typically occurs during the initial account setup and verification process. It is a necessary step to fully activate your account features for US operations.

You may be required to provide your SSN for specific activities. These include sending transfers from US dollars or activating a Wise debit card.¹ The requirement may also arise after account creation if a transaction triggers further regulatory checks.

What If You Don't Have an SSN?

If you are a non-US resident or otherwise do not have an SSN, alternative documentation may be used. An Individual Taxpayer Identification Number (ITIN) is often an acceptable alternative for account verification in the US.¹

The platform allows for other forms of identification, such as a non-US ID for non-US residents sending money from the US.¹ Check your account's verification section for specific options available to you.
