Is an Illinois Resident Permit Valid in Maine?

Why

• Illinois is not on Maine's official reciprocity list.
• Maine allows permitless carry for eligible adults 21+, which extends to visitors who may legally possess a handgun.

Maine recognizes a permit 'issued by another state to its resident' only where that state recognizes Maine's resident permit - non-resident permits are not honored. Extra conditions: permit holders from Alaska, Arizona, Iowa, Kansas, Nebraska, North Dakota and Virginia must be 21+ (Virginia holders must also carry government-issued photo ID). In practice most visitors 21+ may simply carry permitless.

• Maine allows permitless concealed carry from age 21 for people who may legally possess a handgun, including eligible visitors.

Permit not recognized — but permitless carry applies. The answer is the same as for the resident permit on this page.

Not recognized. Reciprocity is decided by the destination state, so the answer in this direction depends on Illinois's law, not Maine's.

Where does Maine publish its official reciprocity list?

Maine publishes its recognition policy on an official state page, linked in the sources on this page. That page is the authority — check it shortly before travel, because recognition lists change without much notice.
