Received a call from this #. They asked for the business owner and began asking about our labor law posters in our place of business. I placed them on hold and they either hung up or lost connection before I was able to click back over but it sounded like a sales call.

Same thing as other posted message.  Have received multiple calls for this type of "compliance" stuff.  Think they target new businesses and then try to sell labor posters.  Which you can get from your state....

Received call from "Federal Compliance". Woman asked to speak with the owner. She started speaking of compliance with federal laws. Cut her off and told here we are in compliance and are not interested in anything she is selling.

Telemarketer plain and simple.

This number has called us everyday for a week. I asked if this was important because she never asks for the owner by name. I explained he was out and she said shed write it in her notes.
I tried calling back and it rings and rings.
I live in the dc area, if this was federal issues it would have a 202 area code.

Katie, read the posts that appear above yours and you should be able to see what's happening.

The reason you can't get through when you try to call back is that the call didn't really come from 360-680-1802 – the Caller ID was faked or "spoofed" to conceal the identity of the caller. That in itself should tell you much about the trustworthiness of the caller, shouldn't it?
