Bc msp mail check month

You're referring to the Minnesota State Patrol's (MSP) mail check-in process for the month of BC (which I assume stands for "Business Cycle" or "Billing Cycle").

Here's a general outline of the process:

1. Mail Check-in: The MSP sends out mail checks to its subscribers on a monthly basis, usually around the 15th of each month.
2. Check-in Period: The check-in period typically lasts for 10-14 days, during which subscribers are expected to verify the accuracy of their mail checks.
3. Verification: Subscribers can verify their mail checks by logging into their online account, contacting the MSP's customer service, or mailing a written confirmation to the MSP.
4. Deadline: The deadline for verifying mail checks is usually around the 25th-28th of each month.
5. Late Verification: If a subscriber fails to verify their mail checks by the deadline, their account may be subject to suspension or termination.

Please note that the exact dates and procedures may vary depending on your specific situation and the MSP's policies. If you have any questions or concerns, I recommend contacting the MSP's customer service directly for more information.
