Fax Connecticut Secretary of State — Cover Sheet and Documents
The difference between a matched filing and a stalled one at Connecticut Secretary of State is usually the cover sheet — here is what to include. Connecticut Secretary of State is the agency that administers business filings in Connecticut, serving residents across southern New England. This page covers what to label, what to fax, and how to find the office's current fax number.
Does Connecticut Secretary of State accept a fax?
Confirm whether the Secretary of State accepts your document by fax before you rely on it — corporate filings are largely online now, while notary, apostille, and correction filings are where fax is more commonly used. Treat fax as one channel alongside online and in-person, not the default for every document.
Finding the official fax number
There is no fax number printed here on purpose — Connecticut Secretary of State routes documents by office and the line changes. Start with the form or notice you are responding to, confirm the number on the agency's official site, and verify it by phone before sending.

Identifiers your fax to Connecticut Secretary of State needs
The cover sheet does the routing work once your fax arrives. Include a callback number so the division can reach you about a fee or a defect. With the identifiers and destination clear, the fax lands where it should on the first try.
Notary, authentication, and business filings you fax
When the entity portal will not take a particular form, fax is often the fallback the division names. Group the signed form and its attachments — a notary bond, an authentication cover sheet — into one PDF. A complete filing packet is what lets the division process it without returning it for more.
