301 604-3305 message states, they are from GSA.org, Wants to update my info.

BRIGHTKEY 301-604-3305.  Received a call from these people only seconds after hanging up on another robo call from (name not found) 224-000-8956.  Scams, and they don't feel the need to observe the do not call list.

They said its call from NASE. and wanted to verify the address

Brightkey is a customer service company. They work for organizations (mostly associations -- they work for ours) who outsource their customer service functions. So, they probably are only calling if you have a business relationship with their client, to verify an address, etc. There are many phone scams out there, but this is not one of them.

this is not one to worry about if you signed up for the NASE (National Association of the Self Employed) .  I recently signed up and they were calling, per the voice mail, to follow-up and discuss the benefits of joining.
