Per my experience , expr in ARRAY_CONTAINS (arr_expr, expr [, bool_expr]) method is not supported list arguments.

According to your situation , I suggest you use UDF in Cosmos DB.

I created 3 sample documents as your description.

[
  {
    "id": "1",
    "zip": [
      {
        "code": "1111"
      },
      {
        "code": "2222"
      }
    ]
  },
  {
    "id": "2",
    "zip": [
      {
        "code": "2222"
      },
      {
        "code": "3333"
      }
    ]
  },
  {
    "id": "3",
    "zip": [
      {
        "code": "4444"
      },
      {
        "code": "1111"
      },
      {
        "code": "2222"
      }
    ]
  }
]

Please refer to the snippet of UDF code as below :

function test(zipcode){
    var arrayList = ["1111","2222"]
    var ret = false ;
    for(var i=0 ;i 

You could select zip array (select c.zip from c) ,then loop the results and invoke the UDF above in your code with the zip[i] arguments.

Hope it helps you.

Just for summary:

Use the IN operator from Cosmos DB SQL APIs to query entry which is included in the list condition.

Like

SELECT * FROM c WHERE c.ZipCodes[0].Code IN ("6500", "6700")

Or

SELECT DISTINCT c FROM c JOIN zc IN c.ZipCodes WHERE zc.Code IN ("2720", "2610")
