USPS Informed Delivery Explained: How to Sign Up Safely, Spot Phishing, and Handle Missing Mail

Understanding USPS Informed Delivery (and similar services): how it works, how to sign up safely, and what to do if mail looks wrong

Late July has a way of turning the mailbox into a daily to-do list: back-to-school forms, travel confirmations, bills, and the random “where did that letter go?” moment. If you’ve ever wished you could get a heads-up about what’s on the way, USPS Informed Delivery is one of the most talked-about options.

But because “mail preview” sounds so useful, it’s also a magnet for lookalike emails and texts that try to trick people into clicking links or paying fake delivery fees. Here’s a practical, safety-first guide to what USPS Informed Delivery does (and doesn’t), how to sign up the right way, and what to do if something seems off—without the panic.

What USPS Informed Delivery does (and doesn’t): set the right expectations

USPS Informed Delivery is designed to give you a digital preview of incoming mail and, in some cases, updates related to packages—depending on what USPS makes available for your address. The key word is “preview.” It’s a convenience feature, not a guarantee that everything will arrive exactly when you expect.

In general, here’s what to keep in mind:

  • Availability can vary by address. Some locations may not be eligible, or may have limited features.
  • Not every piece of mail will appear. Certain items may not show up in previews, and images or updates can be delayed.
  • A preview isn’t the same as delivery confirmation. Seeing an item in a daily preview doesn’t mean it will arrive that same day, and not seeing an item doesn’t automatically mean it’s missing.

If you’re using it as a household organizer—“Oh good, the school packet is coming”—it can be genuinely helpful. Just treat it as informational, not as a security system.

How to make sure you’re using the real USPS site—and not a lookalike

The safest way to sign up for USPS Informed Delivery is simple: start by typing USPS.com directly into your browser (or using the official USPS app), rather than clicking a link from an email or text.

A practical sign-up safety checklist:

  • Navigate directly to USPS.com. Search results and email links can be spoofed; typing the address reduces that risk.
  • Create a strong, unique password. Avoid reusing a password from shopping or social media accounts.
  • Turn on any available security options. If your USPS account offers extra sign-in protection, use it.
  • Keep your account info tidy. Use an email address you check regularly, and review account settings periodically.

Also, be cautious with “helpful” messages that claim there’s a problem with your account. A real service generally won’t pressure you into immediate action through a random link.

Phishing red flags (and the easiest way to verify)

Mail-related phishing often follows the same script: urgency, confusion, and a link. It may claim a package can’t be delivered, that you owe a small fee, or that your account is locked. Sometimes it includes a QR code meant to send you to a fake page.

Common red flags to watch for:

  • Urgent language like “final notice,” “account suspended,” or “deliver today or return to sender.”
  • Requests for payment to “release” a delivery (especially via unusual methods).
  • Odd sender details or misspelled domains that don’t end in usps.com.
  • Unexpected QR codes that push you to scan instead of verifying directly.

The easiest verification habit: don’t interact with the message. Open a new browser window and go straight to USPS.com to check your account or tracking information. If you’re still unsure, look for official guidance on USPS scam reporting through the U.S. Postal Inspection Service.

If mail looks wrong or goes missing: calm, official next steps

If your preview shows something important and it doesn’t arrive—or you suspect misdelivery—start with a few low-stress checks before assuming the worst.

  • Check your household first. Ask if someone else picked it up, and look at common “mail drop” spots.
  • Double-check addressing. Make sure your name is on the mailbox and your address formatting is consistent for senders.
  • Ask neighbors (briefly and politely). Misdeliveries happen, especially in multi-unit buildings.

Then, move to official USPS support tools by navigating directly to USPS.com. USPS typically provides customer service options for tracking, delivery issues, and address-related services (like holding mail or change-of-address processes). If you believe you’re dealing with a scam or mail theft, use the official reporting pathways through the U.S. Postal Inspection Service.

One more smart step: if a suspicious message mentioned your USPS account, change your password (using USPS.com), review recent activity if available, and consider updating your email password too—especially if you clicked anything you regret.
