UL 969 vs. UL 969A: Which Standard Applies to Your Label?

UL 969 and UL 969A cover two different kinds of labels.

UL 969 applies to labels attached with adhesive or molded into a part, including permanent nameplates on enclosures, panels and equipment. UL 969A applies to flag labels, flag tags and wrap-around labels used on flexible cords and hoses.

The distinction matters. These standards use different category control numbers, and a supplier recognized under one is not automatically recognized under the other.

What Each Standard Covers

UL 969, Marking and Labeling Systems, is the older and more widely used standard. It evaluates the entire label construction, including the facestock, ink, adhesive and application surface. These components are tested together to determine whether the label will remain attached and legible after exposure to specified conditions.

UL 969 is referenced by more than 450 UL standards and over 30 ULC end-product standards. That is why it appears on so many specifications and approved-vendor forms.

UL 969A was first published in 2020 to address a different physical challenge. A flag label wraps around a flexible cord or hose and folds back onto itself. Most of the adhesive bonds to the label rather than the surface underneath it. The label also flexes during use and has no rigid substrate supporting it.

Testing that label as though it were a nameplate attached to an enclosure would not tell you much about how it will perform in the real world. UL 969A provides a test method designed for that application.

The current UL 969 standard is Edition 6. UL dates it July 24, 2025, while the ANSI Webstore lists a publication date of July 28, 2025. If you are citing the edition in a specification, it may be helpful to include both dates. UL 969A remains Edition 1 from 2020 and was republished July 2, 2025.

The Fastest Way to Choose

Start with one practical question: How does the label attach?

If the label bonds to a surface and remains there, UL 969 probably applies. Common examples include aluminum enclosures, polycarbonate housings and powder-coated control panels.

If the label wraps around a cord or hose, bonds primarily to itself and leaves a visible flag, UL 969A probably applies.

The category control number, or CCN, provides another way to confirm the standard:

Application:

• U.S. CCN
• Finished printed labels PGDQ2
• Label stock for further printing by the manufacturer PGJI2
• Raw label materials PGGU2
• In-mold labels PGIM2
• Limited-use labels PGIS2
• Flag labels, flag tags and wrap-around labels PGCT2

Canadian category codes generally use the same prefix with an 8 suffix, including PGDQ8, PGJI8, PGGU8 and PGCT8. If the finished product will be shipped into Canada, confirm that the supplier holds the appropriate Canadian recognition. U.S. recognition alone is not enough.

This is also an easy way to catch a mismatch. If a supplier provides a certificate for PGCT2 and your label will be applied to a control panel, they have provided recognition for the wrong type of label.

What UL Recognition Means

Recognition under UL 969 or UL 969A is a Recognized Component certification, not a UL Listing.

That is the correct status for most labels. The label is being qualified for use as one component inside a certified end product. Its job is to meet the applicable requirements without creating a problem for the product’s overall certification.

Recognition is maintained through UL’s Follow-Up Service. This includes periodic, unannounced factory inspections and, when required, additional testing. It is an ongoing quality-control process, not a test report that gets filed away and forgotten.

A supplier’s recognition can also be verified through UL Product iQ. Buyers can search by file number and confirm which constructions and categories are actually recognized. It is worth checking before placing the first order, especially when a label is tied to an end-product certification.

Recognition does not give a supplier permission to print or apply the UL Mark. That requires participation in UL’s Authorized Label Suppliers Program, which is a separate program with its own requirements.

The Detail Many Specifications Miss

UL recognition does not apply to a material in isolation. It applies to a complete construction used on a specific surface and within a defined temperature range.

For example, one published recognized construction rates the same label stock to 80°C on aluminum and galvanized steel, but only 60°C on ABS. The facestock, ink and adhesive remain the same. The application surface accounts for the 20-degree difference.

The printing method matters too. Recognized constructions may identify approved thermal-transfer ribbons by manufacturer and part number. Changing from one ribbon to another, even when the printed label looks identical, can move the finished label outside the recognized construction.

That is why “UL 969 recognized polyester” is not a complete specification. A useful specification should answer several additional questions:

• Under which CCN is the label recognized?
• Which application surfaces are included?
• What temperature rating applies to each surface?
• Which inks, ribbons or printing methods are approved?
• Does the recognition include the Canadian equivalent?

If a supplier cannot provide those details in writing, the recognition may not cover your actual application.

UL recognition is also generally limited to indoor use unless the construction specifically includes outdoor exposure. Outdoor performance is a separate qualification and should never be assumed.

Common Questions

Is UL 969A a newer version of UL 969?

No. They are separate standards for different types of labels. UL 969 covers adhesive-attached and in-mold labels. UL 969A covers flag labels, flag tags and wrap-around labels used on flexible cords and hoses. Recognition under one does not include recognition under the other.

Does UL 969 recognition cover every surface?

No. A recognized construction identifies the approved application surfaces and the temperature rating for each. The same label may have different ratings on aluminum, galvanized steel, ABS or another material. Always confirm that your housing or substrate is specifically included.

What is the difference between UL Recognized and UL Listed for a label?

A Recognized Component is qualified for use inside another certified product. This is the status normally required for a label. A UL Listing generally applies to a complete end product. If a label supplier claims the label itself is “UL Listed,” ask exactly which certification they mean.

Do I need Canadian recognition too?

Yes, if the finished product will be sold or shipped into Canada. Canadian category codes generally mirror the U.S. codes but end in 8, such as PGDQ8, PGJI8, PGGU8 and PGCT8. U.S. recognition by itself does not cover Canadian requirements.

Can changing the printing ribbon affect recognition?

Yes. A recognized construction may identify permitted ribbons by manufacturer and part number. Substituting a different grade, such as switching from resin to wax or changing suppliers, can move the label outside the recognized construction even if the finished print looks the same.
