Caveats
Named-town list is not full Essex or Plymouth county FOM — verify address (Medium). Insurance: Publishes NCUA federal share insurance (typically to NCUSIF limits) plus MSIC Massachusetts excess coverage above NCUA limits — MSIC is not ASI and is not a substitute for NCUA. Confirm current insurer language on the CU site and via the NCUA locator. CIP applies.
Join difficulty rationale
Medium — published Norfolk/Suffolk/Middlesex community path exists, but Essex/South Shore coverage is a named-town list — Medium address-check.

Not a guarantee: Meeting the published field of membership does not mean you will be approved. Credit unions still run identity checks (CIP) and their own account rules.
