Valid question. Should coincide with company name change request.
My broker informed me that anytime a company goes through a name and ticker change, a new cusip is assigned. The name change from Dolat Ventures to JB&ZJMY Co. was on May 3, 2017(amended) and filed May 8, 2017. That coincides with the new Cusip number date.
See Name Change pdf under History on WY SOS site. The Cusip number in the post by Somethinggood matches what has been confirmed by many brokers. Call yours for confirmation on the CUSIP. My broker confirmed the new CUSIP. Tick Talker's post contains a screen shot toward the end of this post.
