Every hearing instrument is unique and can be identified by its
serial number. The location differs depending on the type of aid
you have—Behind-the-Ear (BTE), In-the-Ear (ITE), In-the-Canal
(ITC) or Completely-in-the-Canal (CIC).
BTE
For BTE models, the serial number is located on the battery door. The manufacturer’s
name and the model number can be found on the inner curve of the hearing
instrument.
ITE
For ITE models, the serial number is located in the helix area, along with
the manufacturer’s name and model number. A red or blue bar next to
the number indicates right (red) or left (blue) ear.
ITC
The serial number, manufacturer’s name and model number are all located
on the outer shell of In-the-Canal models. A red or blue bar next to the
number indicates right (red) or left (blue) ear.
CIC
The serial number, manufacturer’s name and model number are all located
on the outer shell of Completely-in-the-Canal models. A red or blue shell
color indicates right (red) or left (blue) ear.
