Mashpee Wampanoag Tribe COVID stimulus Checks will automatically be sent if you received assistance in 2020, we have had delays but should be able to complete the processing before the end of June. COVID Assistance applications are only required for those who were NOT sent assistance checks in 2020. Be reminded, checks will be mailed to the same address when we last distributed membership payments. If you need an address updated please email rita.lopez@mwtribe-nsn.gov or call 508-477-0208 x 173.
