Key Points
- 91% of customers track their shipments, making visibility an important part of the delivery experience for sensitive documents.1
- Sensitive documents, including medical records, financial information, passports and visas, require visibility, reliability and protection.
- Chain-of-custody visibility can help businesses track sensitive documents from shipment through delivery and confirm who received them.
How Does UPS Handle Security Concerns When Shipping Sensitive Documents?
UPS helps address security concerns when shipping sensitive documents through enhanced chain-of-custody visibility and real-time tracking. Depending on the shipment, businesses can also use time-definite delivery and other urgent delivery options to maintain greater control over sensitive documents from origin to destination.
Why is Chain of Custody Important for Sensitive Document Security?
If a passport doesn’t arrive on time, a business trip could be delayed. If loan documents are held up, a family’s first home purchase might be stalled. And if medical records aren’t handled securely, treatment could be interrupted or private details exposed.
For sensitive documents, the way they’re handled in transit matters as much as getting them to their destination on time.
“The consequences of mishandling documents are very real,” says Seth Hoeger, Urgent Documents Strategic Lead, UPS. “Anything with personally identifiable information (PII) is huge, especially when you’re dealing with HIPAA laws, bank account numbers or Social Security numbers.” The HIPPAA Privacy Rule protects individually identifiable health information in any form, including information stored or transmitted on paper.2
What Happens When Sensitive Documents Fall into the Wrong Hands?
When personal details fall into the wrong hands, the impact can extend far beyond a single envelope. Depending on the information involved, exposure can lead to identity theft, financial fraud or other misuse of personal information.3 Different industries also face different document security requirements.
Sensitive documents also contain intellectual property. Draft plans, prototypes or confidential agreements can create business risk if they’re intercepted or exposed. The FBI reports that intellectual property theft costs U.S. businesses billions of dollars each year.4
When Urgent Deliveries of Sensitive Documents Surge
Demand for urgent document delivery can fluctuate throughout the year. That makes shipment visibility especially important during peak paperwork cycles.
Urgent documents don’t follow the same patterns as holiday shopping or retail shipping, Hoeger says. For example, banks and insurers often see sharp spikes in the month after each quarter ends. These are periods when reports and financial records are finalized.
“Our customers who primarily ship sensitive documents don’t follow the traditional winter holiday peak,” Hoeger explains. “For urgent documents, the busiest times are actually April, July, October and January.”
Visibility always matters. People want to know that their sensitive documents are being delivered quickly and safely.
How Does Chain-of-Custody Support Secure Document Delivery?
Sensitive documents often require fast delivery, but speed by itself isn’t enough. Senders also need visibility into the document’s journey and confirmation that it reached its destination.
“People want to know where their documents are throughout their journey,” Hoeger says. “When you’re dealing with legal contracts or anything with personal information, the ability to see who signed, when it was delivered and how it moved through the chain of custody makes a huge difference.”
UPS offers delivery options that can give senders more control over urgent document shipments. Time-definite delivery ensures delivery by a specified time, depending on the service selected. UPS Delivery Intercept® allows businesses to request changs to eligible shipments before the first delivery attempt, including rerouting a package to a different address. And requiring a signature provides confirmation: The document didn’t just move quickly but stayed protected and arrived as intended.
Protecting the Integrity of What’s Inside Urgent Shipments
Even the fastest delivery and most accurate tracking won’t matter if the documents themselves aren't protected in transit.
“One of the biggest challenges with urgent documents is packaging,” Hoeger says. “Traditional envelopes weren’t built for the stakes of today’s shipments.” That’s why UPS has worked with suppliers to create sturdier, more secure options. For senders who want added assurance, UPS also offers envelopes with an inner security pack — a sealed design that protects against tampering or water damage. “It’s an extra safeguard,” Hoeger says. “Customers know their documents are secure inside, even if something happens along the way.”
Combined with time-definite delivery and signature confirmation, packaging built for today’s urgent documents helps reduce risk transit and preserve the trust that comes with secure delivery.
