Show Device Certification Labels auf OnePlus
Older phones carried printed regulatory stickers under the battery cover. Modern OnePlus devices skip the physical label and store the same information digitally, since sealed unibody designs leave no room for a printed sticker.
You need this data mainly for two reasons: proving compliance when importing or reselling a device, and confirming hearing aid compatibility (HAC) before buying accessories. The FCC ID matters if the phone is used or shipped within the United States, since it links the device to its official certification record.
To view the labels, open Settings ➔ About phone ➔ Regulatory labels. This screen lists every certification mark assigned to your specific model, including region-specific entries.
Not every OnePlus model shows the same set of labels. Regional variants sold outside the US may not display an FCC ID at all, and HAC ratings only appear on models that were actually tested for hearing aid compatibility. If a label you expect is missing, it usually means your unit was never certified for that specific standard rather than a settings error.
