When can I use the designation

I have passed the exams, paid the fees and attested to everything…do I now wait for some official confirmation that I am a charterholder and can use the designation? Or can I go ahead now?

I waited until I received a confirmation email from the CFA Institute informing me that my application had been accepted and that I could use designation.

Just had an email to say I am accepted and can use the designation.

Time to change your handle on this forum! Congrats.
