People say "medical card" for three separate things in Massachusetts. Certification comes from a provider. Registration comes from the Cannabis Control Commission. The card is the Program registration card the Commission issues after you register. Each can expire on a different date, and you need the first two active to buy. This page separates them with the Commission wording.

1. Certification

Certification is a written statement from a certifying provider that you have a debilitating medical condition. Before registering, the Commission says you must receive a written recommendation that identifies your qualifying medical condition. The provider then emails you a four-digit PIN. A certification that is not active means you cannot buy, even if your card has not expired.

2. Registration

Registration is your application to the Commission, done online in the Medical Use of Marijuana Program Online System with the PIN, a valid ID and, for most patients, proof of Massachusetts residency. The Commission says registration is free. You renew it every year. A PIN is only needed the first time.

3. The card

The Program registration card is the physical card that arrives in the mail after the Commission approves you. When you enter a Medical Marijuana Treatment Center, the Commission says you present the card and a valid form of identification. You must carry it whenever you possess marijuana for medical use.

Why the dates do not match

The Commission FAQ answers the question people ask most: "My Program ID card is not expired, but the dispensary says it is. What is going on?" Its answer: the date on which your certifying provider certified you may be different from the date your physical card expires. If your medical certification has expired, you cannot buy medical marijuana.

In the Commission words, to purchase, "both your certification from a Certifying Health Care Provider and registration with the Medical Use of Marijuana Program must be active." Renewing means doing both: get recertified by the provider, then log in and complete the registration renewal.

The five steps to a card are on the patient hub, and the renewal steps are on the renewal page.

Short answers

Is the certification the same as the card?

No. Certification comes from a provider. The card comes from the Commission after you register. You need an active certification and an active registration to buy.

Why does the dispensary say my card is expired when it is not?

The Commission says the date of your certification may differ from the date your card expires. If the certification has expired, you cannot buy.

Does registering with the Commission cost money?

No. The Commission says there is no fee to register or to renew. The provider sets the price of the certification visit.

Do I need the PIN every year?

No. The Commission says a PIN is only required the first time you register in the medical program.
