Identifying your Plugable device’s model number and serial number can help with troubleshooting, and warranty support. This article outlines where to find these labels on most Plugable products.
Model Number Location
The model number is typically printed on a label on the underside of the device. On smaller hubs, it may be etched into the chassis instead of appearing on a sticker.
Common model number prefixes include:
- UD-
- TBT-, TBT3-, TBT4-
- USBC-, USB3-, USB2-
- UGA-

Serial Number Location
Most devices also include a serial number (S/N) on the underside:
- Usually printed on a sticker
- On compact devices, it may be etched into the housing
- Some models may show a MAC address instead of a serial number — this can be used in place of the serial number when contacting support
Modern Plugable serial numbers typically follow this format:
####-A#####
(Though variations may exist on older products.)

MAC Address in Place of Serial Number
If your device displays a MAC address instead of “S/N,” you can provide this to the support team as an equivalent identifier.
