The old white square DIP design and modern white round Security+ 3.0 design are different code systems despite sharing a color name.
What this clue means
The manufacturer's identification chart places white square with pre-1993 DIP equipment, whereas its current white round entry is Security+ 3.0. If you cannot see the shape clearly, leave the finder result unverified until you inspect the opener or its manual.
Confirm it on your opener
Find the model sticker and compare the button with the manufacturer identification chart. Fading, replacement circuit boards and similar case designs can mislead you. If you cannot confirm the family, the correct status is unknown.
Next step
Run the finder with the brand, button color and shape. Then use the official compatibility tool or manual to check your particular opener before buying.
What the finder deliberately refuses to do
If you choose “white” without a shape, GarageFit returns unverified instead of displaying the modern white list. This is a safety rail against the most confusing color overlap in the manufacturer chart. A square white button should lead you to the legacy manual and safety review; a round white button can be compared with the current white-family accessory list. Neither route creates an exact opener-model guarantee.
