I Don’t Have A Serial Number

Buffalo requires complete serial number information so we can provide you with the best possible level of service as laid out in our scope of support.


Support will not be provided without a serial number, regardless of contact channel. Not providing a serial number will only delay your service unnecessarily. 


Serial Numbers are 14 digit numbers (no letters) and can be located on your unit


User manuals and additional product downloads are available without the serial number, just enter your model number on the 'downloads' search in the support header menu.


A NOTE FOR OUT OF WARRANTY CUSTOMERS: Buffalo does provide a method for you to get support after the warranty period has expired, but the serial number is still required. Submitting a request without a serial number will result in an email asking you for one. You can submit an out of warranty request here.
