Warranty Void Labels | Tamper-Evident Warranty Seals

Frequently Asked Questions

Q. What is a warranty void label?

A warranty void label is a small tamper-evident seal placed over the opening of a device, usually on a screw, seam, or case joint. If the device is opened, the seal either breaks or leaves a VOID mark, making it clear that it has been opened. The label often says "Warranty Void if Seal Broken" or "Warranty Void if Removed."

Q. Where should I put a warranty void label?

Place a warranty void label wherever the device actually opens, such as over a case screw, across the seam where two panels meet, or on the joint of a housing. The goal is to open the unit to break the seal. A label placed on a flat, unimportant spot will not be effective.

Q. How does a warranty void label show tampering?

A warranty void label shows tampering in two ways. Some leave a repeating VOID pattern on the surface when peeled off. Others are made to break apart and crumble rather than come off in one piece. In both cases, you cannot remove the seal and put it back without it being obvious.

Q. What are warranty void labels made from?

Warranty void labels are usually made from destructible vinyl, VOID polyester, or metalized foil. Destructible vinyl tears apart when removed. VOID polyester leaves the word VOID on the surface. Metalized foil gives a shinier, harder-to-copy finish. The material affects how noticeable the evidence of tampering is.

Q. Can warranty void labels be customized with my logo and a serial number?

Our warranty void labels can be customized with your company name, warranty terms, a logo, sequential serial numbers, or a barcode. Serial numbers are important because a numbered seal links one device to one label, so no one can quietly swap a new seal onto an already opened device.

About our Warranty Void Labels

We make warranty void labels. These are tamper-evident seals that go over the screws and seams of a device, making it clear if someone opens it. If you try to peel one off, it either leaves a VOID pattern or breaks apart. Neither option comes off cleanly. Manufacturers and repair shops use these labels to detect unauthorized opening, protect resale value, and ensure that "no user-serviceable parts inside" is enforced.

• Leaves a VOID mark or self-destructs upon any attempt to open.
• Print your company name, warranty text, a serial number, or a barcode directly on the seal.
• Choose destructible vinyl, VOID polyester, or metalized foil, in stock colors or a custom design.
• Small seals are sized to fit over a single screw or cover a full seam.
