Does USPS Send Text Messages? What's Real and What's a Scam
If you've ever received a text claiming to be from the United States Postal Service, you've probably wondered whether it's legitimate. USPS does use text messaging in specific, limited ways — but the volume of fake USPS texts circulating makes this one of the most important distinctions to understand before you click anything.
Yes, USPS Can Send Text Messages — Under Specific Conditions
USPS offers a legitimate text notification service called USPS Text Tracking. When you opt into this service, you can receive SMS updates about your package's status — things like "Out for Delivery" or "Delivered."
Here's the key detail: you have to request these texts first. USPS does not send unsolicited text messages about packages you haven't signed up to track via SMS. The process works like this:
- You visit USPS.com and look up a tracking number
- You opt in to receive text alerts for that specific shipment
- USPS sends updates from the number 28777 (2USPS)
That's the official channel. If a text arrives from a different number, especially a standard 10-digit phone number, that's a significant red flag.
What Legitimate USPS Texts Actually Look Like
Genuine USPS text messages are narrow in scope. They:
- Reference a specific tracking number you're already aware of
- Don't include clickable links asking for payment or personal information
- Come from 28777, not a random phone number
- Notify you of delivery milestones, not problems requiring urgent action
USPS does not text you to:
- Collect unpaid postage or customs fees via a link
- Confirm your address by clicking a URL
- Reschedule a delivery through a third-party website
If a text does any of those things while claiming to be USPS, it isn't.
The Smishing Epidemic: Fake USPS Texts Are Extremely Common 📱
Smishing — SMS phishing — is a widespread attack vector, and USPS is one of the most impersonated organizations in the world. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and USPS's own Postal Inspection Service have both issued repeated warnings about fake USPS texts.
These fake messages typically:
- Claim a package couldn't be delivered and needs address confirmation
- Include a link to a convincing-looking but fake USPS website
- Ask for a small "redelivery fee" via credit card
- Harvest your payment credentials or install malware
The fake sites are often sophisticated — they copy USPS branding closely. The tell is usually the URL, which won't end in usps.com.
How to Tell a Real USPS Text from a Fake One
| Feature | Legitimate USPS Text | Fake/Phishing Text |
|---|---|---|
| Sender number | 28777 | Random 10-digit number |
| Contains a link | Rarely; no payment links | Almost always includes a URL |
| Requests payment | Never | Frequently asks for small fee |
| You opted in first | Yes | No — arrives unsolicited |
| Urgency language | Neutral tone | "Act now" or "package held" |
| URL format (if present) | usps.com domain only | Lookalike domain |
Other Official Ways USPS Contacts Customers
USPS uses several communication channels, and it helps to know where each one fits:
- Email notifications — Available through USPS Informed Delivery, which gives you a preview of incoming mail and package updates. You sign up at usps.com.
- USPS Mobile App — Push notifications for tracked packages through the official app
- Automated phone calls — Used in some delivery exception scenarios
- Physical notices — A PS Form 3849 left at your door when a delivery attempt fails
📬 Informed Delivery is USPS's most feature-rich notification system and worth knowing about separately — it emails you scanned images of letter-sized mail pieces before they arrive, alongside package tracking.
Variables That Affect Your Experience With USPS Notifications
Not everyone interacts with USPS texts the same way, and a few factors shape what you'll actually encounter:
Whether you've opted in is the single biggest variable. If you've never signed up for USPS Text Tracking, any USPS-branded text you receive is almost certainly fraudulent.
How the sender shipped the package matters too. If someone ships you a package via a third-party carrier service or a shipping aggregator, you may receive texts from that platform — not USPS directly — even if USPS ultimately delivers it. Services like ShipBob, Shopify Shipping, or Amazon Logistics each have their own notification systems.
Your phone carrier and spam filtering settings can affect whether legitimate texts from short codes like 28777 reach you at all. Some carriers block or flag short-code numbers, which could mean you don't receive texts even after opting in.
International shipments introduce additional complexity. Customs delays, handoffs between postal services, and different tracking systems mean notifications may come from a non-USPS source even for packages destined for a U.S. address.
What to Do If You Receive a Suspicious Text
If you get a text claiming to be from USPS and you're not sure:
- Don't click any links in the message
- Go directly to usps.com in your browser and enter your tracking number manually
- Forward the suspicious text to 7726 (SPAM) to report it to your carrier
- Report it to USPS at postalinspectors.uspis.gov
Whether a specific text in your inbox is real or fraudulent depends on whether you opted in, what number it came from, what it's asking you to do, and whether it references a shipment you're actually expecting. Those details are the difference between a routine delivery update and a credential-harvesting attack.
