Fax Connecticut Unemployment Insurance — What to Send and How
Before you fax Connecticut Department of Labor about a unemployment claim, it helps to know what actually moves by fax in Connecticut — and what does not. For Connecticut residents in southern New England, Connecticut Department of Labor is the office behind the state's unemployment insurance program. This page covers what to fax, how to find the office's current fax number, and how to send it securely.
Does Connecticut Department of Labor accept a fax?
You generally cannot file a new unemployment claim by fax; the online and phone systems handle that. Fax comes in when you are appealing a determination or sending documents the agency requested. That one check keeps you from faxing into a system that may only take online filings.
Finding the official fax number
Because Connecticut Department of Labor handles a unemployment claim through different offices, the right fax depends on your document. Check the form's instructions or the notice, verify the line on the official site, and keep it with your file.

When to fax the unemployment agency
The documents that actually move by fax in an unemployment case are appeals and the proof behind them. Group the determination notice, your written appeal, and the supporting proof into one transmission. Faxing beats mail when the clock on the determination is already running.
The honest way to get the Connecticut Department of Labor fax number
