Narrative:

Leveled at FL220 for approximately 30 mins when I understood and read back a clearance to climb to FL230 (frequency 124.3). Handed over to ZKC, 125.3, who informed me the clearance to FL230 was for another aircraft. Seems like we need a backup to reading back clrncs to ATC, since my readback was never corrected, if indeed it was for another aircraft.

Title: PLT OF AN SMT TURBO PROP RESPONDED TO A CLB CLRNC FOR ANOTHER ACFT.

Narrative: LEVELED AT FL220 FOR APPROX 30 MINS WHEN I UNDERSTOOD AND READ BACK A CLRNC TO CLB TO FL230 (FREQ 124.3). HANDED OVER TO ZKC, 125.3, WHO INFORMED ME THE CLRNC TO FL230 WAS FOR ANOTHER ACFT. SEEMS LIKE WE NEED A BACKUP TO READING BACK CLRNCS TO ATC, SINCE MY READBACK WAS NEVER CORRECTED, IF INDEED IT WAS FOR ANOTHER ACFT.
