How to Read Your Blue Cross Blue Shield Insurance Card
Your BCBS card has about 8 different numbers on it. Maybe more. The receptionist just asked for your “policy number” and you’re staring at the card thinking… which one is it? Good news: every field on that card has a purpose, and none of them are as complicated as they look.
Here’s every number on the front and back of your Blue Cross Blue Shield card, explained in plain English. Doesn’t matter which of the 34 BCBS companies issued yours. The layout changes slightly between companies, but the core fields are the same.
Tap any highlighted field on the card below to see exactly what it means.
Now, the full breakdown of every field.
Where Is the Policy Number on Your Card?
The policy number is the longest number on the front of your card. It’s usually labeled “Member ID,” “Identification Number,” or “Policy #.” All three mean the same thing. On most BCBS cards, it starts with a 3-letter alpha prefix (like XOF or TEA) followed by your unique digits.
This is the single biggest source of confusion on BCBS cards. “Policy number,” “member ID,” and “subscriber ID” are all used interchangeably depending on the form you’re filling out and which BCBS company you have. If a form asks for a “policy number” and you only see “ID #” on your card, that’s the one.
That 3-letter alpha prefix at the front? It identifies which of the 34 BCBS companies manages your plan. XOF might mean Blue Cross Blue Shield of Texas. YZF might be Anthem Indiana. You can look up your prefix on our homepage to find your exact company.
If you’re a dependent on someone else’s plan, your policy number may be identical to the subscriber’s. That’s normal. Providers verify you using your name and date of birth alongside the shared ID number.
Where Is the Group Number?
The group number is on the front of your card, usually labeled “Group #” or “GRP.” It identifies your employer’s specific insurance plan. Everyone at the same company who picked the same plan shares the same group number. If you bought individual coverage (not through an employer), your card might not have a group number at all.
Here’s something most people don’t know: group numbers aren’t permanent. BCBS companies like Anthem change them every 1 to 2 years when employers restructure or renegotiate contracts. If your physical card shows one group number and your online portal shows a different one, the portal is usually correct. The physical card is outdated.
One important exception. Federal Employee Program (FEP) cards do NOT have a group number. If you’re a federal employee with BCBS, you’ll use enrollment codes instead: Self Only is 111, Self Plus One is 113, and Family is 112. These substitute for the group number on any form that asks for one. If the form requires a group number and your card doesn’t have one, write “N/A.”
Also, don’t confuse the medical group number with the Rx Group number (labeled “RXGRP” on some cards). The Rx Group is only used for pharmacy claims. They’re different numbers for different systems.
Where Is the Member ID?
Your member ID is the main identification number on the front of your card. On most BCBS cards, it’s the same as your policy number. It starts with a 3-letter alpha prefix followed by numbers. If you’re a dependent on a family plan, you and the primary subscriber often share the same member ID.
Can’t find your member ID because you lost the card or don’t have it with you? A few options. Check the BCBS mobile app, log into the member portal online, or dig through your email for a welcome letter from your BCBS company. You can also call customer service with your SSN and date of birth ready and they’ll pull it up. More on that in our guide on how to find your info without your card.
New members sometimes panic because they haven’t received a card yet. Your coverage is active from your effective date regardless of whether the physical card has arrived. Cards typically show up within 7 to 10 business days. If yours hasn’t come, register for an online account to get a digital card immediately.
What Is the Difference Between Subscriber ID and Member ID?
The subscriber is the person who holds the policy. Usually the employee whose job provides the insurance. The member is anyone covered under that policy, including the subscriber, their spouse, and dependents. If you ARE the subscriber, these two numbers are identical. If you’re a dependent, the subscriber ID belongs to the person whose employer provides the insurance.
Anthem specifically asks for both “Subscriber ID” and “Member ID” on some of their online forms. If you’re the policyholder, enter the same number for both fields.
Quick tip from people who’ve dealt with this: if your full member ID (with the alpha prefix) doesn’t work on an online form, try dropping the first 3 letters and entering just the numbers. Some systems don’t accept the alpha prefix and will reject the whole entry for no apparent reason.
One more thing. The subscriber’s name appears on ALL cards for that entire plan. So if your spouse’s name is on your card instead of yours, you don’t have the wrong card. That’s standard for dependent coverage.
Where Is the RX Bin Number?
The RX Bin (Bank Identification Number) is a 6-digit code used to process prescription claims at the pharmacy. On most BCBS cards, it’s printed on the BACK of the card, not the front. Look for a section labeled “Pharmacy” or “Prescription Benefits” on the reverse side. It’s usually right next to the RXPCN and RXGRP numbers.
The RX Bin routes your prescription claim to the correct insurance processor. When a pharmacist says “your card isn’t working,” one of the most common fixes is simply re-entering the RX Bin number. The pharmacy system needs three pieces of information from the back of your card: RX Bin, RXPCN, and RXGRP. If any one of those is wrong, the prescription claim rejects. More info on fixing that in our card not working troubleshooter.
If your card does NOT have an RX Bin number anywhere on it, your plan might not include prescription drug coverage. Or your pharmacy benefits might be managed by a separate company (like CVS Caremark or Express Scripts) with its own card. Check with your employer or call the member services number on your card to confirm.
Where Is the PCN Number?
The PCN (Processor Control Number) is printed next to the RX Bin on the back of your card, in the pharmacy benefits section. It works alongside the RX Bin to route your prescription claims to the correct processor. Pharmacies need both numbers to submit a prescription claim.
PCN and RX Bin always work as a pair. If the pharmacist asks for your PCN, flip your card over and look in the cluster of pharmacy numbers near the bottom. You’ll usually see three fields bunched together: RXBIN, RXPCN, and RXGRP. The RXGRP is your prescription group number, and it’s separate from your medical group number on the front. They serve different systems entirely.
What Is the Payer ID on Your Card?
The payer ID (also called the EDI number) is a 5-character alphanumeric code assigned to each BCBS company. Medical offices use it to submit claims and verify your eligibility electronically. On most BCBS cards, the payer ID is on the back, in a section labeled “Provider” or “Claims Submission.”
Honestly, this number matters more to your doctor’s billing department than to you. But if a billing office asks you for it, flip the card over and look near the claims address.
Each of the 34 BCBS companies has its own payer ID. BCBS of Texas has a different one than BCBS of Illinois, which has a different one than Anthem in California. If the billing office has the wrong payer ID on file, claims get rejected even though your insurance is perfectly valid. Knowing your alpha prefix helps the billing staff identify the right payer ID for your specific plan.

What Is the Plan Name on Your Card?
The plan name tells you which specific benefit package you have. It’s usually printed on the front of your card, sometimes in a colored banner or near the top. Common names include “Blue Access,” “Blue Choice,” “Blue Advantage,” “Choice Plus,” and “Open Access Plus.”
The plan name often includes your network type. If it says “Choice Plus PPO,” you have a PPO plan. “Blue Advantage HMO” means you have an HMO. That distinction matters for whether you need referrals and how your coverage works in other states.
If a form asks for a “Plan ID” and you don’t see a specific number for it, use your group number. In many BCBS systems, the group number doubles as the plan ID for administrative purposes. And if your card says something generic like “Health Select” without specifying PPO or HMO, it likely functions as an HMO. Call the number on the back of your card to confirm your plan type.
What Does the Suitcase Logo Mean?
The small suitcase icon on your BCBS card is the BlueCard symbol. It means your insurance works nationwide through the BlueCard program, not just in your home state. If you see a provider in another state who accepts their local BCBS plan, your card works there too.
Here’s the useful part. The suitcase tells you your plan type at a glance:
- Empty suitcase (no text inside): Your plan has out-of-area coverage but is NOT a PPO. Usually an HMO. Benefits may vary by situation.
- Suitcase with “PPO”: You have a PPO plan with full BlueCard access. You can see providers nationwide at in-network rates.
- No suitcase at all: Your plan may not include out-of-area benefits. Government programs like Medicaid typically don’t show the suitcase.
The BlueCard program connects all 34 BCBS companies into one national network. If you travel or live in a different state from where your plan is based, this icon is how the provider’s billing office knows how to process your claim.
What Do the Suffixes (01, 02, 03) Mean After Your Member ID?
The 2-digit suffix after your member ID (like -01, -02, -03) identifies which family member is covered under the plan. Typically, 01 is the primary subscriber (the employee), 02 is the spouse, and 03 or higher are children.
Not every BCBS company uses suffixes. Some assign completely unique member IDs to each family member instead of using suffixes on a shared base number.
If a form asks for your member ID, include the suffix if you have one. Some provider systems need it to pull YOUR specific records rather than the subscriber’s. Without it, the system might default to the primary account holder’s information and the copay or benefit details could look wrong.
Know your 3-letter prefix? You can look up your exact BCBS company and find your provider phone number right now.
