Thieves posing as couriers are ringing doorbells across Mexico City and banking on routine. A uniform, a thermal bag, a clipboard—just enough to get someone to unlatch the door. CDMX police issued a warning this week and urged residents to report suspicious “deliveries” through 911 and the Mi Policía app. The pattern isn’t random; authorities say crews stage fake orders, watch for access points, then move fast. We spoke with neighbors, reviewed police guidance, and looked at recent trends to explain what’s happening—and how to shut the door on it.

The knock sounds ordinary. The outfit looks familiar. That’s the point. Mexico City police are warning residents about fake delivery robberies, a simple ruse that turns good manners—opening the door for a courier—into an open invitation for thieves.

Police say crews imitate food or package delivery services, then use the moment at the doorstep to push inside or case a property for a quick entry when no one answers. The alert isn’t theoretical; it follows recent detections tied to this method across several neighborhoods, according to the capital’s police department.

What the police say is happening

Investigators describe a basic script. Someone orders to your address—or pretends to. The “courier” arrives with a bag, helmet, or branded box. If the door opens, they stall with a made-up mix-up, ask for a signature, or request a code. If it stays closed, they may probe gates, watch for exits, or coordinate with lookouts to force an entry when residents step away. Authorities emphasize fast reporting through 911 and the Mi Policía app, which routes calls to the quadrant chief for quicker response.

The warning lands amid a growing delivery culture in the city. Police posts on official social channels highlight the disguise—motorbike, backpack, receipt—and urge neighbors to verify any unexpected knock before unlatching. That includes checking order histories, asking the building manager to receive packages, or redirecting deliveries to staffed pickup points. The message from authorities is simple: control the doorway.

There’s context for the concern. In recent months, national outlets have reported that police in the capital identified the “false courier” scheme as part of a broader pattern of home targeting. These alerts aren’t about panic; they are about habits—pausing long enough to confirm an order, keeping video intercoms on, and not sharing verification codes through the door.

Fake delivery robberies

Mexico City isn’t dealing with this in a vacuum. Fraud tied to delivery brands surged last year, from “phantom package” calls to verification-code thefts that hijack messaging accounts. That’s a different crime than a doorstep break-in, but it exploits the same trust in the delivery ecosystem—and it primes households to act on supposed delivery “issues.” The throughline is simple: don’t pay unexpected fees, don’t share codes, and confirm on official apps.

So what should residents do tonight? Treat every knock like a transaction you control. If you didn’t order, you don’t open. Speak through the door or intercom. Ask the courier to leave the item with your building’s front desk or show the order details through the camera—no codes, no phones passed under the gate. If something feels off, call 911 and report it through Mi Policía. That creates a record, alerts your quadrant, and helps officers spot patterns faster.

The city’s safety picture is complicated—some crimes are declining, others shifting—but the threshold to stop this one is surprisingly low. A closed latch. A quick check on your phone. A neighbor’s heads-up in the building chat. The disguise works only if courtesy outruns caution. Slow the moment down, keep the barrier in place, and most fake delivery robberies end at the buzzer.
