Change of Address or Name on a Patient Registration

If your name, address or contact details change, you update them in your account with the Medical Use of Marijuana Program Online System. The Commission says to do it within five days, and the regulation says within five business days. A name change and a residential address change each need an uploaded document. A mailing address change does not.

What needs a document

As of October 31, 2026. Source: Commission FAQ and patient pages.
Change	What you upload
Name	A legal document proving the name change, and updated proof of identification that shows the new name
Residential address	A proof of residency document
Mailing address	No documents
Email address or phone number	No documents; change them in your account
ID with a new expiration date	The new ID; update your account within five days of the change

How to update

The Commission says to log in to your account with the Medical Use of Marijuana Program Online System, select "My Registration" at the top of the screen, then click "Edit". After you enter the updated information, click the "Update" button. The Commission points to the Patient guide in the portal for step-by-step instructions on uploading documents.

How soon

The Commission patient pages say to update your account within five days of a change to your name, address, contact details, or when your government-issued ID has a new expiration date. 935 CMR 501.015(6) puts it as notifying the Commission within five business days after any change in the information you submitted. To stay inside both, do it within five days.

Proof of residency documents

For a residential address change you upload a document that shows your new address. The Commission lists these:

Utility bill (gas, electric, telephone, cable or heating oil) less than 60 days old
Current Massachusetts motor vehicle registration card
Tuition bill with a due date less than six months old
Car insurance policy or bill less than 60 days old
Mortgage, lease or loan contract less than six months old
Certified U.S. marriage certificate dated within the past six months
Property tax or excise tax bill for the current year
First-class mail from a federal or state agency less than 60 days old
Current state-issued professional license with your address

The Commission says it does not accept an identification document, pay statement, doctor or hospital bill, credit card bill or savings or checking account statement as proof of residency. Files larger than 3 MB will not upload, and the Commission suggests reducing the size of a phone photo.

When you renew

You can also change your name or address during renewal. The Commission renewal page says to update any changes, and to submit a new valid ID if the ID you used has expired. The same applies to caregiver details. The renewal steps are on the renewal page.
