No, it’s nationwide, all carriers and mvnos are signed on to the US Block Status since IMEI became standard. It’s a separate list from the global GSMA and not all carriers in the US report to the GSMA like they should,but if a device is reported lost or stolen in the US it cannot be activated by a US carrier until resolved.

Except I have used unlocked IMEI blacklisted devices on different carriers, so if one exists in theory, it doesn’t appear to be there in practice.
