You cannot use an SSN to directly look up a Medicare number on a public search tool, but you can find it by logging into a My Social Security Account.

How to Find Your Medicare Number

  • Social Security Account: Log in to your account on SSA.gov and view or download your Benefit Verification Letter, which lists your Medicare number.
  • Medicare Account: Log in to your secure account on Medicare.gov to view your card details or print a replacement.
  • Call Support: Contact 1-800-MEDICARE (1-800-633-4227) to speak with a representative who can help verify your identity and provide your number.
  • Medical Providers: Healthcare providers and billing offices can use secure administrative portals with your personal details and SSN to look up your Medicare Beneficiary Identifier (MBI) if you are receiving care.

For further assistance, consider the specific scenario:

  • For Personal Use: Accessing the official government portals mentioned above requires verifying the identity of the account holder.
  • For Providers: Accessing the MBI lookup tool requires authentication through an authorized Medicare Administrative Contractor (MAC) portal.

Following the designated steps on official agency websites provides the most direct path to obtaining the necessary information.

Does SSA have my Medicare number?

Yes, you can find your Medicare number on your Social Security Account by viewing or downloading your Benefit Verification Letter.

How to Find Your Medicare Number

  • Go to the Social Security Administration Portal and sign in to your account.
  • Look for the Benefit Verification Letter link on your account dashboard.
  • Download or open the letter as a PDF file.
  • Locate the Medicare Information section of the letter to view your unique Medicare Number and your Part A and Part B start dates.

Is my Medicare number the same as my member ID?

Your Medicare number is not the same as a member ID if you have a private Medicare Advantage (Part C) or a private prescription drug (Part D) plan.

Medicare Number vs. Member ID

  • Medicare Number: Also called the Medicare Beneficiary Identifier (MBI), this is a unique 11-character code with numbers and letters found on your red, white, and blue Medicare Card. It identifies you with the federal government's Original Medicare program.
  • Member ID: If you join a private insurance plan (like a Medicare Advantage plan or a separate Part D drug plan), that specific insurance company gives you their own card with a separate member ID number.

Which One to Use

  • Original Medicare: Use your federal Medicare number.
  • Private Plan: Use the member ID on your private plan's card when you go to the doctor or pharmacy for that specific coverage.

What does your Medicare number look like?

The Official CMS Medicare Overview states that the Medicare ID—known as the Medicare Beneficiary Identifier (MBI)—is an 11-character alphanumeric code.

Format Structure

The MBI follows this 11-character breakdown (N = Number, A = Letter, A/N = Letter or Number):

  • Position 1: Number (1–9, excluding 0)
  • Position 2: Uppercase letter
  • Position 3: Letter or number
  • Position 4: Number (0–9)
  • Position 5: Uppercase letter
  • Position 6: Letter or number
  • Position 7: Number (0–9)
  • Position 8: Uppercase letter
  • Position 9: Uppercase letter
  • Position 10: Number (0–9)
  • Position 11: Number (0–9)

Key Rules

  • No Hidden Meaning: Characters are randomly generated and "non-intelligent," meaning they contain no personal data or Social Security Numbers.
  • Excluded Characters: The letters S, L, O, I, B, and Z are never used to prevent confusion with numbers.
  • Dashes: While cards may print hyphens (e.g., 1EG4-TE5-MK73) for readability, you must enter the ID without dashes or spaces during electronic billing or online lookups.
