Chart Or Publication
After landing in Myrtle Beach on Runway 36 we were asked to exit left on B5; turn left on B; left on B3; short of 36. We were then cleared to cross 36 and taxi to the ramp via A4. However the A4 on the airport does not match our charts. Our charts list A4 as taxiway Z. We stopped the aircraft and inquired with Tower; who said that proceeding straight would put us on A4 and that our charts are incorrect. The chart should be updated to reflect the changes on the ground as soon as possible. [Caused by] incorrect taxi diagram almost lead to an incorrect turn on an active runway. Suggest chart needs to be updated to reflect actual taxiways at the airport.
Air carrier First Officer reported MYR airport diagram indicates taxiway A4 as Z.
