Letter of Authorization (LOA) Apostille & Authentication
Letter of Authorization
Empower your representatives globally. A Letter of Authorization is a formal document that allows a third party to act on your behalf or on behalf of your company for specific tasks. To be legally recognized by foreign customs, banks, or government agencies, your LOA must be officially apostilled or legalized.
At US Apostille, we provide expedited authentication for Letters of Authorization from all 50 U.S. States. We ensure your delegation of authority is processed through our Maryland hub in just one business day.
Mandatory: Original Documents & Notarization
Physical Requirement: To secure an Apostille, you MUST mail the original Letter of Authorization bearing an original "Wet-Ink" signature and the original seal of a Notary Public to our office.
Digital scans, PDFs, or photocopies are NOT accepted. The Secretary of State requires the physical notary impression to verify the document's authenticity before issuing the Apostille.
Common Uses for Apostilled Letters of Authorization
Customs & Logistics: Authorizing an agent to clear shipments or handle import/export matters.
Corporate Representation: Authorizing an individual to represent the company before a foreign government body.
Banking Access: Granting specific staff the authority to perform limited banking tasks abroad.
Telecommunications & Utilities: Authorizing a local manager to set up corporate services in a foreign office.
