Parking Permits: Choosing and Managing Windshield Decals

Parking permits do one job: they let whoever is enforcing a lot tell, from a few yards away, whether a vehicle is authorized to be there. For most lots the practical choice is a numbered windshield decal in a color assigned to a lot, zone or permit year, with an adhesive matched to how long the permit is meant to stay on the vehicle. PolyLabel supplies these as 2½ × 1½ in decals in seven colors, printed right-read or mirror-image, with removable adhesive as standard and permanent adhesive as an option. This guide covers the decisions to make before you order, and how to run the annual changeover once the program is in place.

Why a permit program exists

A parking permit answers two questions for the person walking the lot: is this vehicle allowed here, and if not, what happens next. Without a permit, enforcement means checking every plate against a list. With a permit, the check is visual: the decal is present, it is the right color for this lot and this year, and the number is legible. Anything else gets a notice, a tow or a call to the office.

The same decal also ties the vehicle to a record. The number on the windshield points to a line in the register that names the permit holder, their unit or department, and the plate the permit was issued against. That record is what makes it possible to answer a complaint, resolve a dispute over a space, or cancel a permit when someone leaves.

The program that run smoothly were designed around enforcement from the start, whether that is a condo board separating resident and visitor parking, an employer with a lot smaller than its headcount, or a school keeping student vehicles out of the staff lot.

Hang tag or windshield decal

The first decision is the format, and it comes down to whether the permit belongs to a person or to a vehicle.

Hang tags hook over the rear-view mirror. They move between vehicles, and they can be lent to someone who is not supposed to have one. They suit a household that shares one permit across two cars, and lots where the permit holder will not accept anything stuck to the glass.

Windshield decals adhere to the glass and stay with the vehicle. One vehicle, one permit. They cannot be passed around and they are always visible. The cost is that a permit holder who changes vehicles needs a replacement decal rather than simply moving the tag.

PolyLabel supplies windshield decals. If your program needs a hang tag, the numbering and color decisions below still apply; the adhesive and print-orientation choices apply to decals only. Where a household needs to cover two vehicles, the decal answer is two numbered decals against the same record.

Right-read or mirror image: decide which side of the glass

Parking permit decals are printed in one of two orientations, and the choice is about where the decal will be applied.

Right-read decals are printed the normal way and applied to the outside of the glass. The text reads correctly from where it is stuck, and the instruction to the permit holder is just to stick it on.

Mirror-image decals are printed reversed and applied to the inside of the windshield, facing out. Read through the glass from outside the vehicle, the text appears the right way round. The decal sits inside the cabin, away from weather, car washes and anyone on the outside who might peel it off.

Pick one orientation for the whole program. Enforcement staff need to know where to look, and a mixed lot slows every check. If your lot includes heavily tinted glass, test readability of a mirror-image decal through the tint before committing. All PolyLabel parking permit decals are available either right-read or mirror-image, so orientation is a line on the order rather than a different product.

Removable or permanent adhesive

The adhesive should match how long the permit is meant to stay on the vehicle, and what happens when it is no longer valid.

Removable adhesive is the standard for parking permits and the right default for most program. It suits annual renewal, where every decal comes off and is replaced with the new year’s color, and it suits staff turnover, tenants who move out, and leased or company vehicles that will be returned.

Permanent adhesive is for permits that are meant to stay put for the life of the assignment. Fleet vehicles that will always park in the same yard, long-term contractor vehicles, or lots where the operator specifically wants removal to be difficult. Choose permanent only when you are confident the decal will not need to come off cleanly at renewal.

Neither adhesive is designed to be lifted and moved to another vehicle. When a permit holder changes vehicles, issue a replacement decal with a new number and mark the old number void in the register. An old decal that turns up on the wrong vehicle can then be identified as such.

Color-coding by lot, zone or year

PolyLabel parking permits are printed one color with black numbering on a white background, in red, blue, light blue, green, gold, purple and black. Seven colors is enough to encode one meaning per color, and the meaning you choose should be the one enforcement staff need most at a glance.

By lot or zone. Each lot, or each zone within a large lot, gets a color. A green decal in the blue lot is a violation without reading a single number. This is the common choice for property managers with several lots and for campuses that separate staff, student and visitor parking.

By permit year. Each year gets a new color, so an expired permit is obvious from across the lot. Rotate through colors so the same one is not reused while old decals from that color’s year might still be on the road.

By holder type. Resident, visitor, contractor, staff. This works where the lot is one space but the rules differ by who is parked in it, for example a condo with time-limited visitor parking.

Color carries one message; everything else lives in the number. A program that encodes zone, year and holder type all in color runs out of colors and confuses the people doing the checking.

Sequential numbering makes enforcement and reissue manageable

Parking permit decals from PolyLabel are printed with a sequential number inside a box, or with no numbering at all. Specify the numbered version unless you have a specific reason not to.

The number is the link between the windshield and the register. Color tells enforcement whether the vehicle belongs; the number tells them who it belongs to. When a permit is lost, stolen or cancelled, the number goes on a stop list, and any decal carrying it is treated as invalid regardless of color or year. When a replacement is issued, it takes the next number in the series. Numbers are never reused, because a reused number means two records pointing at one decal.

Plan the number range around the year’s demand plus replacements. Decals are sold in quantities of 100 to 500, so order enough to cover renewals, new permit holders and an allowance for lost or damaged decals, rather than placing a second order mid-year in the same color.

Running the annual changeover

A permit program that renews annually needs a changeover process, and it is easier to run if it is the same every year.

• Set the color and number range for the coming year before ordering, and record both in the register.
• Order ahead of the renewal date so decals are on hand before renewal notices go out.
• Distribute with placement instructions. State which side of the glass, and where on the windshield, so the lot stays consistent.
• Allow a grace period during which both the old and new colors are valid, then enforce against the old color.
• Reconcile the register at the end of the grace period: every issued number matched to a holder, every unissued number accounted for, every voided number listed.

Removable adhesive keeps the physical part simple: the old decal comes off, the new one goes on, and the register is updated.

Specifying your parking permits

Parking permits come down to four decisions: decal rather than hang tag, right-read or mirror-image depending on which side of the glass, removable or permanent adhesive depending on how long the permit lasts, and a color scheme that carries one meaning while the sequential number carries the rest. The Parking Permits category lists all seven colors in the standard 2½ × 1½ in size. For a different size, or a custom logo on the decal, contact us directly.
