Frequently asked questions
What is a diplomatic courier service?
A diplomatic courier service is a specialized shipping operation that transports sealed diplomatic pouches and confidential materials between embassies, consulates, and government agencies. Couriers are security-cleared, manifests are encrypted, and shipments are protected under the Vienna Convention on Diplomatic Relations — meaning the pouch cannot be opened or detained by transit authorities.
How does a diplomatic pouch work?
A diplomatic pouch is any sealed container — from a small envelope to a full freight crate — that carries official correspondence, documents, or articles intended for official use. Each pouch is marked with visible external signs of its diplomatic character and travels with a courier who carries an official document confirming their status. In transit, the pouch is exempt from search or seizure.
Who can use diplomatic courier services?
Diplomatic courier services are reserved for accredited embassies, consulates, permanent missions, and authorized government agencies. Private companies cannot ship under diplomatic pouch protection, but they can use secure high-trust courier services (like ShipSafe's sealed-pouch commercial tier) that mirror the chain-of-custody controls without the treaty protections.
What can be sent in a diplomatic pouch?
Official correspondence, government documents, digital media, cryptographic material, and articles for official use. Weapons, narcotics, and items in commerce are prohibited. ShipSafe's diplomatic team reviews every manifest before dispatch to ensure compliance.
How is chain of custody maintained?
From collection to delivery, every diplomatic shipment stays with a vetted courier or under sealed CCTV custody. Tamper-evident seals, GPS-tracked containers, and signed handoff logs at each transfer point create an unbroken audit trail delivered to the receiving mission on arrival.
