Business Letter Apostille & Authentication Services

Business Letter Digital / Online Notarized

Give your corporate correspondence global legal weight. A Business Letter is often required by foreign authorities to verify company details, authorize transactions, or confirm employment status. To be accepted by a foreign bank, embassy, or government office, your official business letter must be apostilled or legalized.

At US Apostille, we provide expedited authentication for Business Letters from all 50 U.S. States. We ensure your corporate communications are processed through our Maryland hub in just one business day.

Mandatory: Notarization & Originality

Important Requirement: To secure an Apostille, your Business Letter MUST be notarized by a licensed Notary Public. The Notary verifies the identity and signature of the company officer who signed the letter.

Can I send a Digital Copy?

  • Yes (In Specific Cases): We accept digital PDFs ONLY if they were notarized via Remote Online Notarization (RON) with a verifiable electronic seal.

  • Physical Original Required: For standard notarizations (ink and stamp), you MUST mail the original hard copy to our office. Most foreign embassies (like UAE or China) still require physical originals for legalization.
