Frequently Asked Questions (FAQs)

BCBS prefixes primarily identify local entities and do not directly indicate international coverage. For international coverage, BCBS members should look for logos like Blue Cross Blue Shield Global on their member ID cards or visit GeoBlue's website for specific information regarding their international health plans.

No, BCBS prefixes cannot be used to verify patient identity. They are designed to identify the specific plan a member belongs to, not the individual member. For accurate verification, the full member ID number along with other personal information, such as date of birth, should be used.

New BCBS prefixes are issued based on member enrollment and plan changes rather than on a set schedule. They are assigned when new members join or existing members switch plans, making the issuance frequency variable and driven by member activity.

No, retired individuals do not have different BCBS prefixes compared to non-retired members. BCBS prefixes are determined by the specific plan a member belongs to, not their retirement status. Both retired and non-retired members on the same plan will share the same prefix on their BCBS ID cards

No, the BCBS prefix alone cannot reliably identify fraudulent activities. Fraud detection requires verifying member information, monitoring for unusual activity, and being aware of common fraud schemes like upcoding and phantom billing. The prefix only aids in identifying the plan and region.
