Person Master Index (PMI) is a unique identifier number created by eligibility systems such as MAXIS and METS. A consumer having a PMI number does not necessarily mean they have active health care coverage. The ARC does not give out PMI numbers for cases that are not active. PMIs are used by health care providers to identify coverage and bill for services. 

When contacting the ARC for a PMI number, please keep in mind that they are not accessible through METS. We must navigate multiple systems to retrieve this information. Thank you for your understanding and patience.

Alternatively, if you have sufficient personal identifiers for your consumer, you can obtain PMI numbers directly through the Renewal Lookup Tool.
