Identification Information
Your hearing instruments have a serial number
engraved on them. The location of the serial
number will vary according to the style of hearing
instrument you have chosen.
The year of manufacture is incorporated into the
serial number. Please note the warranty is based
upon the date of purchase, not the date of
manufacture. The serial number may look similar
to this sample: AS12345. The second letter of
this serial number refers to the year of
manufacture of the hearing instrument. The
letters S or T indicate the year of manufacture of
your BTE as 2008. Your Audiologist or Hearing
Care Provider can answer any questions you may
have about the identifying code on your hearing
instrument.
Record the serial numbers of each instrument in
the space provided for future reference.
