# What is a Medicaid CIN number and where do I find it? > Your CIN is an 8-character code on your New York Medicaid card — required to call MAS and book a free ride. Here's where to find it and what to do if lost. Source: https://dachiplus.com/resources/what-is-a-cin-number-medicaid/ Updated May 2026 Your **CIN (Client Identification Number)** is the unique ID on your New York Medicaid card — an 8-character code made up of two letters, five numbers and a final letter (e.g., AB12345C). MAS requires it to verify your eligibility when booking a Medicaid transportation trip. Find it in the upper right area of your Medicaid card, or call [1-800-664-1800](tel:+18006641800) (NY Medicaid helpline) if you've lost your card. The CIN is the one piece of information MAS absolutely requires before booking a transportation trip. Here's everything you need to know about it. ## How to find your Medicaid CIN - **Get your NY Medicaid Benefit card** — Your CIN (Client Identification Number) is printed directly on the card. - **Look for the 8-character code** — It’s typically two letters, five numbers, and one letter (e.g., AB12345C). - **No card handy? Check your paperwork** — The CIN also appears on your Medicaid award/eligibility letter and your managed-care card. - **Still can’t find it? Call for help** — Contact your local Department of Social Services or your Medicaid managed-care plan. - **Use it to book with MAS** — Give the CIN to MAS at 1-844-666-6270 when you schedule your ride and request DachiPlus. ## What is a Medicaid CIN number? CIN stands for **Client Identification Number**. It is the unique identifier assigned to every New York State Medicaid member. Your CIN is used across all Medicaid services — including transportation — to verify that you are an active member and to look up your coverage details. A New York Medicaid CIN follows this format: **two letters + five numbers + one letter** (for example, AB12345C or XY98765D). It is sometimes also called a Medicaid ID number or Member ID, depending on which plan or document you're looking at. Two things about that code are worth knowing before you call MAS. The first is that the trailing letter is part of the CIN — people frequently read off the first seven characters and stop, and a partial CIN fails eligibility verification exactly as an incorrect one does. The second is that the CIN is not the same as the Medicare number some dual-eligible members also carry; if you hold both, MAS wants the Medicaid CIN specifically, and offering the Medicare number instead is one of the more common reasons a first booking call stalls. ## Where do I find my CIN on my Medicaid card? Your CIN appears on your New York Medicaid card (also called the Common Benefit Identification Card or CBIC). Look for it: - **On the front of the card** — typically in the upper right or center area, labeled "CIN," "Member ID," or "ID Number." - **On correspondence from New York State Medicaid** — any letter from the Department of Social Services or Office of Health Insurance Programs will reference your CIN. - **On your Medicaid Managed Care plan's card** — if you have Healthfirst, MetroPlus, Fidelis, or another managed care plan, your member ID on that card is typically your CIN. ## What do I do if I lost my Medicaid card or don't know my CIN? If you've lost your card or can't find your CIN, here are your options: - **Call the NY Medicaid helpline at 1-800-664-1800.** Have your name, date of birth, and address ready — they can look up your CIN. - **Call your Medicaid Managed Care plan** (Healthfirst, MetroPlus, Fidelis, etc.) — they can provide your member ID, which is your CIN. - **Log into NY State of Health** (nystateofhealth.ny.gov) if you enrolled through the marketplace — your CIN should be visible in your account. - **Visit your local Department of Social Services office** — they can verify your enrollment and give you a replacement card. MAS cannot look up your CIN for you — you need to have it before calling to book a trip. ## Why does MAS need my CIN to book transportation? MAS uses your CIN to verify in real time that you are an active Medicaid member before authorizing a trip. This prevents unauthorized billing and ensures the provider is paid correctly. Without a valid CIN, MAS cannot confirm your eligibility, and the trip cannot be booked as a Medicaid-covered trip. If your Medicaid coverage has lapsed (e.g., you missed a renewal), MAS will be unable to book the trip even if you have your CIN. In that case, contact your local DSS office to reinstate your coverage, or book with DachiPlus as a private-pay trip at [(516) 754-7777](tel:+15167547777). ## Does my CIN number change if my Medicaid plan changes? Your CIN (the 8-character code) stays the same as long as you are enrolled in New York Medicaid, even if you switch between managed care plans. However, individual plan member IDs may differ. When calling MAS, use the CIN from your state-issued Medicaid card, not a plan-specific member ID — they should match, but the state CIN is definitive. ## Medicaid CIN — FAQ ## How do I book Medicaid medical transportation in Suffolk or Nassau County?
