# Adds fingerprint properties to v2 bank account objects ## What’s new Adds the [fingerprint](https://docs.stripe.com/api/v2/money-management/payout-methods/object.md?api-version=2026-10-28.preview#v2_payout_method_object-bank_account-fingerprint) property to bank account [Payout Method](https://docs.stripe.com/api/v2/money-management/payout-methods/object.md?api-version=2026-10-28.preview), [GB Bank Account](https://docs.stripe.com/api/v2/core/vault/gb-bank-accounts/object.md?api-version=2026-10-28.preview), and [US Bank Account](https://docs.stripe.com/api/v2/core/vault/us-bank-accounts/object.md?api-version=2026-10-28.preview) objects in API v2. US Bank Account objects also include the [fedwire_fingerprint](https://docs.stripe.com/api/v2/core/vault/us-bank-accounts/object.md?api-version=2026-10-28.preview#v2_us_bank_account_object-fedwire_fingerprint) property for accounts that use Fedwire routing numbers. Fingerprints are unique, deterministic identifiers that help you recognize the same bank account across API contexts, including API v1 and API v2. API responses always include at least one fingerprint. US Bank Account responses include `fingerprint`, `fedwire_fingerprint`, or both. ## Impact Use fingerprint properties to: - **Deduplicate bank accounts**: Identify and consolidate the same bank account across recipients. Learn how to [detect duplicate bank accounts](https://support.stripe.com/questions/how-can-i-detect-duplicate-cards-or-bank-accounts). - **Maintain blocklists**: Flag and block specific bank accounts by their fingerprint. - **Match accounts across API namespaces**: Identify the same bank account in API v1 and API v2 using their fingerprint values. ## Changes #### REST API | Parameters | Change | Resources or endpoints | | --- | --- | --- | | `fingerprint` | Added | [V2.Core.Vault.GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2.MoneyManagement.PayoutMethod.bank_account](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `fedwire_fingerprint`, `fingerprint` | Added | [V2.Core.Vault.UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### Ruby | Parameters | Change | Resources or methods | | --- | --- | --- | | `fingerprint` | Added | [V2::Core::Vault::GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2::MoneyManagement::PayoutMethod::BankAccount](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `fedwire_fingerprint`, `fingerprint` | Added | [V2::Core::Vault::UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### Python | Parameters | Change | Resources or methods | | --- | --- | --- | | `fingerprint` | Added | [V2.Core.Vault.GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2.MoneyManagement.PayoutMethod.BankAccount](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `fedwire_fingerprint`, `fingerprint` | Added | [V2.Core.Vault.UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### PHP | Parameters | Change | Resources or methods | | --- | --- | --- | | `fingerprint` | Added | [V2.Core.Vault.GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2.MoneyManagement.PayoutMethod.bank_account](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `fedwire_fingerprint`, `fingerprint` | Added | [V2.Core.Vault.UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### Java | Parameters | Change | Resources or methods | | --- | --- | --- | | `fingerprint` | Added | [v2.core.vault.GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [v2.moneymanagement.PayoutMethod.bank_account](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `fedwireFingerprint`, `fingerprint` | Added | [v2.core.vault.UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### Node.js | Parameters | Change | Resources or methods | | --- | --- | --- | | `fingerprint` | Added | [V2.Core.Vault.GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2.MoneyManagement.PayoutMethod.bank_account](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `fedwire_fingerprint`, `fingerprint` | Added | [V2.Core.Vault.UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### Go | Parameters | Change | Resources or methods | | --- | --- | --- | | `Fingerprint` | Added | [V2CoreVaultGbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2MoneyManagementPayoutMethodBankAccount](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `FedwireFingerprint`, `Fingerprint` | Added | [V2CoreVaultUsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | #### .NET | Parameters | Change | Resources or methods | | --- | --- | --- | | `Fingerprint` | Added | [V2.Core.Vault.GbBankAccount](/api/v2/core/vault/gb-bank-accounts/object?api-version=2026-10-28.preview#v2_gb_bank_account_object), [V2.MoneyManagement.PayoutMethod.BankAccount](/api/v2/money-management/payout-methods/object?api-version=2026-10-28.preview#v2_payout_method_object-bank_account) | | `FedwireFingerprint`, `Fingerprint` | Added | [V2.Core.Vault.UsBankAccount](/api/v2/core/vault/us-bank-accounts/object?api-version=2026-10-28.preview#v2_us_bank_account_object) | ## Upgrade #### REST API 1.
