    【Question】
    Provide the zip codes and area codes of the postal points with the community post office type at the elevation above 6000. community post office type refers to type = 'Community Post Office'; elevation above 6000 refers to elevation > 6000;

    【Evidence】
    community post office type refers to type = 'Community Post Office'; elevation above 6000 refers to elevation > 6000;

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T1.zip_code, T1.area_code FROM area_code AS T1 INNER JOIN zip_data AS T2 ON T1.zip_code = T2.zip_code WHERE T2.type = 'Community Post Office ' AND T2.elevation > 6000
