Business Letter Authentication for International Use

Purpose of Authentication

Business letters must be authenticated to be accepted by foreign authorities, banks, government offices, or corporate entities. Authentication confirms the signature, notarization, and issuing authority so the document is recognized outside the United States.

Required Steps

• Notarization
  The business letter must be signed and notarized when required before submission.

• State Authentication
  The notarized business letter is certified by the Secretary of State where it was executed.

• U.S. Department of State Processing
  Federal processing is completed when required for international use.

• Apostille or Embassy Legalization
  The final step is completed based on the destination country’s requirements.

Important Notes / Requirements

• Original signed business letters are commonly required. Copies may not be accepted.

• The letter must be finalized before notarization. Drafts or incomplete versions are rejected.

• Missing notary details, mismatched dates, or unsigned pages often cause delays.

• Business letter examples or templates must be properly executed to be valid.
