BCBS Prefix List

A few things to note about this list:

There are hundreds of prefixes on this list that are no longer assigned to a plan but were in the past. I’ve left those on the site for now. They’re labeled “unassigned” where the plan name should be. If you think leaving them on the list adds clutter let me know and I can remove them.

There are some new Anthem prefixes that are national accounts and I have no idea which plan they belong to. Those will be labeled “Anthem” or “Anthem National Accounts” until I can track down the home plan.

If you find any that need to be added, please send them to me via email by using the Contact Us page.
