Health insurance cards contain several numbers and codes that identify you as a member and provide important details about your coverage. Two common ID numbers on insurance cards are policy numbers and member ID numbers. Are they the same thing? Or do these numbers serve different purposes?
Understanding how to read your insurance card is key to getting the most out of your benefits. This guide explains the difference between policy numbers and member IDs, along with other key items on insurance cards.
What is a Policy Number?
The policy number on your health insurance card is a unique identifier assigned to your specific insurance plan. This number allows your insurance company to access your account information and coverage details.
Your policy number is the key piece of information your health providers need to submit claims and receive payment from your insurer. It links the care you receive back to your plan’s contracted rates and benefits.
Some key facts about policy numbers:
Each insurance policy has its own unique policy number, even within the same insurance company.
The policy number stays the same as long as you keep the same health plan. It only changes if you switch plans.
Every insured member on the same policy shares the same policy number.
Your policy number can also be called a subscriber number or member policy number.
On insurance cards, it may be labeled as “Policy #”, “Policy ID”, “Subscriber #”, or similar terms.
Your policy number is the critical identifier your providers use for filing claims. So it is important to verify it is correct on your insurance card. Contact your insurer immediately if you find any errors.
What is a Member ID Number?
In addition to your policy number, you may also have a member ID or subscriber ID number on your insurance card. This is a unique number identifying you as an individual member on the plan.
While the policy number is tied to the plan itself, your member ID number is specific to your identity as an insured member.
Key details on member ID numbers:
Each covered member on a policy is assigned their own member ID number.
Your member ID number remains the same even if the policy number changes.
On your insurance card, it may be labeled as “Member ID”, “Member #”, “Subscriber ID”, or similar terms.
Your member ID number is sometimes, but not always, different from your policy number. Some insurers use the same number for both.
Your member ID number helps insurers match services you receive to your identity as a member on the plan. But it is not usually required by your healthcare providers for submitting claims.
Are Policy Numbers and Member IDs Interchangeable?
Whether policy numbers and member ID numbers are the same depends on the specific insurance company and how they format member identification numbers. There are a few possibilities:
Same Number – Some insurers use an identical policy number and member ID number for each insured member. In this case, the numbers serve dual purposes of identifying the plan benefits and the individual member together.
Different Numbers – Other insurance companies assign unique member ID numbers that are completely separate from the overarching policy number. The numbers will be different on your insurance card.
Variations of the Same Number – In some cases, the member ID may be your policy number plus an additional digit or characters indicating your place in the family. For example, your policy number might be 123456. Your member ID could be 1234567, with the extra digit specifying you as the first family member on the plan.
Group Policy Number – For employer group health plans, insurance cards may pair the group policy number from your employer with your personal member ID number.
The best way to clear up any confusion is to check your insurance card or contact your health plan administrator. Ask whether your policy number and member ID are the same or different.
Why Do Insurance Cards Have So Many Numbers?
You may wonder why insurance cards need separate numbers to identify the policy, group plan, and individual member. There are a few reasons multiple numbers are useful:
Claims processing – Linking your care to the correct plan benefits requires your policy number. But identifying you as the member who received services needs your member ID.
Coordination of benefits – If you have coverage under two plans, multiple ID numbers help coordinate claims between your primary and secondary insurer.
Family plans – Unique member numbers help differentiate between family members covered under the same policy.
Administrative changes – Your member ID stays with you if you change insurance plans. The policy number identifies the new coverage.
Data tracking – Unique identifiers allow detailed data analytics across large insurance populations.
While it may seem redundant, each number actually serves a distinct purpose for insurers and healthcare providers.
Where to Find Your Insurance ID Numbers
The fastest way to identify your policy number and member ID is to check your insurance card. These numbers are almost always printed on your card for easy reference.
typically find your policy number on the front of the insurance card. It may be labeled as “Policy #”, “Policy ID”, “Subscriber #”, or similar terms.
Your member ID number, if different from your policy number, is also usually on the front of the card. It may be labeled as “Member ID”, “Member #”, “Subscriber ID”, or other similar language.
If your insurance card only lists one ID number without clarifying if it is a policy or member number, you can contact your insurer for clarification. Their customer service team can identify which type of number is printed on your card.
Why Do Providers Need Your Policy Number?
Now that you know the difference between your policy number and member ID number, you may be wondering why healthcare providers focus on collecting your policy number.
When you visit the doctor’s office, hospital, or other healthcare facility, they need to properly bill services to your insurance plan to get paid. To do this, they submit a claim using your policy number.
This links the medical services you received to the contracted payment rates established between the provider and your insurer. Your policy number tells the insurer what benefits you are entitled to under your specific plan.
While your member ID number also helps identify you as the patient, the policy number does the heavy lifting to direct payment. The provider relies on your correct policy number to receive maximum reimbursement from your health plan.
