Of course. Did one or both apportioned plates remain?
Yes, both.
Then you must send in the apportioned plate and your old cab card within 30 days after you receive your new apportioned plates. Failure to return your license plates can result in suspension of your IRB account. The IRB will issue new apportioned plates that have a different number, along with a new matching cab card.
I also need more information about International Registration Plan . Is it possible to move my IRP registration over the internet?
