Incorrect.  As of March 2012 667 was added as an "overlay" area code to areas already served by 410 and 443.  There's a notice about this posted online.  Was able to Google that and found details within first 10 results.

The Maryland Public Services Commission (PSC) posted it on the web.  I just double-checked and it was hte first result.  http://webapp.psc.state.md.us/intranet/Telecom/Area%20Code%20FAQs_v3.htm

cid =baltimore,md.  Because we have so many scam calls, we no longer answer and we block all calls with names or numbers we don't recognize.
