Where Do You Need Authorized Personnel Only Decals?

Mark restricted areas clearly with custom-printed vinyl decals built for doors, windows, equipment, and vehicles

An authorized personnel only decal is a vinyl graphic that marks a door, window, machine, or vehicle compartment as off-limits to anyone without clearance. It sets a clear boundary for visitors, contractors, and staff without drilling holes, mounting sign hardware, or installing a gate. Decals.com prints custom vinyl decals to order in the USA, in your size, material, and wording, and ships them ready to apply.

Quick Answer: Put authorized personnel only decals on any entry point or object the public or untrained staff should not access: server rooms, electrical and mechanical rooms, loading docks, chemical storage, medication rooms, staff-only corridors, job-site trailers, and fleet vehicle compartments. Mount them at eye level, about 60 inches from the floor, on the door panel or glass itself. Printed calendered vinyl suits most indoor and outdoor doors, reflective vinyl suits dim areas, and cut vinyl lettering gives glass doors a clean, no-background look.

Key Takeaways
  • An authorized personnel only decal restricts access to a room, area, or object without the cost of a mounted sign.
  • Most door decals run 4x6 to 8x10 inches; Decals.com prints from 2x2 up to 50x120 inches.
  • Calendered vinyl lasts up to 5 years outdoors; reflective vinyl adds nighttime visibility for docks, gates, and vehicles.
  • Short, recognized wording works best: "Authorized Personnel Only," "Employees Only," or "Restricted Area: No Admittance."
  • Standard production is 3 business days, with 1- and 2-day rush and 5-day saver options.

Common Questions About Authorized Personnel Only Decals

What does an authorized personnel only decal mean?
It means only people with permission from the business, such as trained employees, maintenance staff, or approved contractors, may enter the marked area or handle the marked equipment. Everyone else, including customers and visitors, should stay out. A decal communicates that rule at the exact point of entry.
What size authorized personnel only decal should I order for a door?
Most door decals run between 4x6 and 8x10 inches, large enough to read from several feet away without covering the door glass or panel. A common sign rule is about 1 inch of letter height for every 10 feet of viewing distance. Decals.com prints vinyl decals from 2x2 inches up to 50x120 inches, so you can scale up for garage doors and dock entrances or down for cabinets and control panels.
Can I order a custom authorized personnel only decal instead of a generic template?
Yes. Generic decals sold on online marketplaces usually come in one fixed size, font, and wording. A custom authorized personnel only decal lets you set your own text, logo, colors, and dimensions so it matches your facility branding and safety program. Adding your logo signals that the restriction is official company policy, not a generic warning.
Are authorized personnel only signs required by OSHA?
OSHA does not require one universal "authorized personnel only" sign. Some areas do require restricted-entry marking. For example, OSHA 29 CFR 1910.303 requires conspicuous warning signs forbidding unqualified persons from entering rooms with exposed live electrical parts. Many facilities also follow the ANSI Z535 format, usiAre authorized personnel only signs required by OSHA?ng a blue NOTICE header for policy messages. Check the rules for your industry and location. 
What material holds up best for an outdoor restricted area decal?
For exterior doors, gates, and equipment, calendered vinyl with a glossy or matte laminate lasts up to 5 years outdoors when properly applied. In low-light areas, 5-mil engineering-grade reflective vinyl adds nighttime visibility and is rated for 3+ or 5+ years depending on the laminate. On glass entrances, clear decals let the message show without a visible background. 
How do I install an authorized personnel only decal on glass or metal doors?
Clean the surface with isopropyl alcohol, let it dry fully, then apply the decal using the squeegee method to avoid air bubbles. Die-cut and kiss-cut decals apply easily to flat glass and painted metal. For placement guidance on different surfaces, see our post on where to put stickers.
How much do employees only door decals cost in bulk?
Pricing depends on size, material, cut style, and quantity, and the per-unit cost drops as quantity goes up. If you are labeling many doors, machines, or vehicles across one facility or several locations, request a custom quote for volume pricing. 
How fast can I get employees only door decals produced and shipped?
Standard production is 3 business days at no added cost. Decals.com also offers 1- and 2-business-day rush options and a 5-business-day saver option; see full production times. Production starts after proof approval, and orders approved after 5:00 PM CST start the next business day. Shipping is separate, and most U.S. orders arrive 2 to 4 business days after production; see shipping info. 
How do I install an authorized personnel only decal on glass or metal doors?
Clean the surface with isopropyl alcohol and let it dry fully. Tape the decal in position, peel the liner, and squeegee from the center outward to push out air. Die-cut and kiss-cut decals apply easily to flat glass and painted metal. Follow our step-by-step guide to installing a vinyl decal for the full process. 
Can I remove an authorized personnel only decal later?
Yes. Properly applied vinyl decals remove cleanly from glass, metal, and painted surfaces with gentle heat and a slow peel. For short-term restrictions, such as renovations or events, low-tack vinyl window clings come off and reposition easily. Our guide on how to remove a decal covers each surface. 
Do I need to send print-ready artwork, or can Decals.com help with the design?
You can upload EPS, PDF, JPG, TIFF, or PNG files up to 100 MB, or send a simple text request with your wording, font, and colors and the in-house design team will lay it out. Logo recreation starts around $15. To check color and finish before a full run, order custom samples. 

Common Places to Apply Authorized Personnel Only Decals

Authorized personnel only decals belong anywhere a business needs to control foot traffic, protect equipment, or keep people away from hazards. Office buildings use them on server rooms, electrical panels, IT closets, and HR file storage. Warehouses and manufacturing plants post them on loading docks, machine rooms, compressor rooms, and chemical storage areas.

Hospitals and clinics rely on them for medication rooms, labs, and staff-only corridors. Restaurants and retail stores use an employees only door decal on kitchens, stockrooms, and back offices. Construction sites place a restricted area decal on job trailers, tool cribs, and equipment sheds to keep untrained visitors away from hazards.

Fleet and utility vehicles often carry a restricted area decal on cargo doors and equipment compartments. Manufacturers that build machinery can add restricted-access markings at the factory through OEM decal manufacturing. Beyond doors, custom wall decals can mark a hallway entrance, and custom floor decals can mark a stop line in front of a restricted door or aisle. For glass doors and storefront windows, our guide to window decal placement explains where a decal reads best. 

Choosing Material, Finish, and Wording

The right authorized personnel only decal for a climate-controlled hallway is not always right for an outdoor gate. Interior doors, drywall, and cabinets do well with printed calendered vinyl in a glossy or matte laminate. Matte cuts glare under bright overhead lights, while glossy makes colors look sharper.

Exterior doors, gates, and equipment need the same laminated vinyl rated for outdoor use, and reflective vinyl when the area is dark at night. Glass doors work best with window decals or a clear decal so light still passes through. For a crisp painted-on look with no background, custom vinyl lettering is cut from pre-colored vinyl and applied letter by letter with transfer tape. On painted walls, vinyl wall lettering gives the same clean result. High-performance cast vinyl and 3M 

Controltac are wrap films, so they only make sense when the restricted-area message is part of a full vehicle wrap.

Wording that people recognize
Keep wording short and familiar. The most recognized phrases are:
  • Authorized Personnel Only: the standard for offices, warehouses, and utility rooms
  • Employees Only: best for customer-facing businesses like restaurants and retail stores
  • Restricted Area: No Admittance: stronger language for secure or hazardous zones
  • Authorized Personnel Only Beyond This Point: useful on corridors and floor stop lines

Use high-contrast colors, such as white on blue, black on yellow, or white on red. Facilities following ANSI Z535 often use a blue NOTICE header for policy messages and reserve DANGER, WARNING, or CAUTION headers for actual hazards. Adding your company logo shows the restriction is official policy rather than a generic label. 

Authorized Personnel Only Decal vs. Sign: Which Should You Use?

A decal is the better choice when the message belongs on the door, glass, or equipment itself. It costs less than a rigid sign, needs no screws or adhesive mounts, cannot be pried off easily, and works on curved or uneven surfaces like machine housings and vehicle doors. A rigid or post-mounted sign makes more sense for open areas with no wall or door, such as a fenced lot or a driveway entrance. Many facilities use both: a sign at the perimeter and an authorized personnel only decal on each controlled door inside.

Placement Best Practices for Restricted Area Decals

  1. Mount at eye level. Center the decal about 60 inches from the floor so people see it before they reach for the handle.
  2. Put it on the door, not beside it. A decal on the door panel or glass is seen at the moment of entry; one on the wall next to it is easy to miss.
  3. Apply to glass panes only. On glass doors, keep the decal inside the glass and off the frame or trim for a clean look and better adhesion.
  4. Mark both sides when needed. For double-swing doors or two-way corridors, apply a decal to each side.
  5. Pair with floor markings. A floor decal in front of high-risk rooms stops people before they reach the door.
  6. Install in the right conditions. Apply on a clean, dry surface at moderate temperatures; see our installation guides for surface-specific tips.
