The best COVID-19 door sign depends on the message you need to communicate: a quarantine decal for restricted access, a visitor notice for entrances, a social-distancing sign for waiting rooms, or a delivery instruction for the front door. The five options below include different sizes and mounting styles. SignMission’s quarantine decal is best for a compact warning, while its visitor and delivery signs offer larger, more specific messages. The ExcelMark name plate is not a COVID-19 notice, but may help identify an office door.
| Product | Best suited for | Format |
|---|---|---|
| SignMission Quarantine Do Not Enter | Restricted-access doors | 7 × 5-inch adhesive vinyl decal |
| SmartSign Social Distancing | Waiting rooms | 10 × 14-inch plastic sign |
| SignMission No Visitors | Visitor-controlled entrances | 14 × 10-inch adhesive vinyl decal |
| SignMission Leave Deliveries at Door | Delivery instructions | 14 × 10-inch rigid plastic sign |
| ExcelMark Custom Name Plate | Office or room identification | 2 × 8-inch custom name plate |
SignMission Quarantine Do Not Enter Decal

This 7 × 5-inch commercial-grade vinyl decal is designed to display a “Quarantine Do Not Enter” message. Its adhesive backing is intended for indoor or outdoor surfaces, and the product description says it can be removed without leaving sticky residue. SignMission also describes the decal as suitable for long-term use in demanding environments.
Best for: Buyers who need a compact, direct warning on a door or other smooth surface. It was selected because its message is specifically about quarantine and restricted entry. Limitation: The 7 × 5-inch format is smaller than a standard wall sign, so consider whether it will be visible from the approach to the door.
SmartSign Waiting Room Distancing Sign

The 10 × 14-inch sign asks visitors to maintain social distancing in the waiting room. It is made from 55-mil HDPE plastic, with digitally printed graphics and an overcoat for added protection. Pre-punched mounting holes are included. The manufacturer says it can be used indoors or outdoors and may last up to two years outside.
Best for: Clinics, offices, and other spaces where visitors wait near one another. Its location-specific message is clearer than a general COVID-19 notice in a waiting area. Limitation: It communicates distancing guidance, not quarantine instructions or a no-visitors policy.
SignMission COVID-19 No Visitors Decal

This 14 × 10-inch vinyl decal states that visitors are not allowed due to COVID-19. Its larger format may be easier to notice at an entrance than a small decal. The commercial-grade adhesive vinyl is described as suitable for indoor and outdoor use and removable without sticky residue.
Best for: Facilities that need to communicate a visitor restriction at the entrance. It was selected for its explicit message and larger size. Limitation: Choose another option if visitors are allowed under specific conditions or if you need a delivery-only instruction; this sign states that visitors are not allowed.
SignMission Leave Deliveries at Door Sign

This 14 × 10-inch rigid plastic sign asks delivery workers to leave packages at the door. It is made from commercial-grade polystyrene and has four pre-drilled quarter-inch mounting holes and rounded corners. Unlike an adhesive decal, it is designed to be mounted through those holes.
Best for: Homes or workplaces seeking a specific contact-free delivery instruction. It was selected because the message addresses a common door-side delivery need. Limitation: The sign does not provide a no-entry or general visitor restriction, and installation requires a suitable mounting location.
ExcelMark Custom Door Name Plate

The ExcelMark 2 × 8-inch name plate can be customized and comes in 14 color choices. Buyers can select a desk holder, a wall holder, or no holder. It is intended for workplace identification rather than communicating COVID-19 guidance.
Best for: Offices that need to identify an employee or room alongside a separate safety notice. It is included as an adjacent door-labeling option, not as a COVID-19 sign. Limitation: It does not carry quarantine, visitor, distancing, or delivery instructions.
Buying Guide: How to Choose a COVID-19 Door Sign
What message does the door need to communicate?
Match the wording to the action you want visitors to take. Choose a quarantine or no-entry message for restricted access, a no-visitors notice for a closed facility, a distancing sign for a waiting area, or a delivery instruction for package drop-offs. A generic notice may be less useful when people need a specific direction.
Should you choose a decal or a rigid sign?
An adhesive vinyl decal can be applied directly to a suitable surface and may be removed without sticky residue, according to the SignMission product descriptions. A rigid plastic sign is a better fit when you want a sign with pre-drilled mounting holes. Check the door or wall material and installation needs before choosing.
How large should the sign be?
Consider how far away a visitor will be when they need to read it. The 7 × 5-inch quarantine decal is compact; the 10 × 14-inch and 14 × 10-inch options offer larger formats. Place the sign where approaching visitors can see it without blocking other door information.
Can these signs be used outdoors?
The product descriptions identify the vinyl decals and SmartSign plastic sign as suitable for indoor or outdoor use. The SmartSign listing says the sign can last up to two years outside. Exposure, placement, and installation conditions can affect how well a sign performs, so follow the product’s mounting guidance.
