Keep getting calls from this number and caller ID says SSI.  They don't leave a message and call at all hours starting as early as 7:30 and as late as 9:00pm!

To many people, SSI means Supplemental Security Income.

However, these calls might be coming from "Survey Sampling International" - and these types of calls are exempt from the federal Do Not Call registration. They should not be calling before 8 am, however.

There have been complaints about this company on several other phone numbers on 800notes.
This phone number might be a new one they are using, maybe because of aa new client, maybe to get past call blockers.

They have a webpage that describes three different ways you can give them a number that they are to not call :

This is not Social Security - this is Survey Sampling International, doing surveys for other companies, and they call incessantly.  I've blocked 4 different numbers from this company.

No message left.

This number keeps calling 5-6 times a day early morning to after 9 at night.
