1.Create a SNS by searching SNS in the console and subscribe any email or anything like HTTP or ….then under policy we will get by default script like below.

{
    "Version": "2008-10-17",
    "Id": "__default_policy_ID",
    "Statement": [
      {
        "Sid": "__default_statement_ID",
        "Effect": "Allow",
        "Principal": {
          "AWS": "*"
        },
        "Action": [
          "SNS:GetTopicAttributes",
          "SNS:SetTopicAttributes",
          "SNS:AddPermission",
          "SNS:RemovePermission",
          "SNS:DeleteTopic",
          "SNS:Subscribe",
          "SNS:ListSubscriptionsByTopic",
          "SNS:Publish"
        ],
        "Resource": "arn:aws:sns:ap-northeast-1:084251039480:ee",
        "Condition": {
          "StringEquals": {
            "AWS:SourceOwner": "084251039480"
          }
        }
      }
    ]
  }

2.Here we have to edit 3 places out of those one is 7th line from bottom “StringEquals” to “ArnLike” and one more is “AWS:SourceOwner” to “AWS:SourceArn” and one more is value of source owner from default value like “54322423456” to S3 bucket ARN that is like “ARN:AWS:S3:::venkybucket”.
3.Then under s3 bucket goto properties and then under event notification we can add this sns and it will work otherwise it will throw error.

{
  "Version": "2008-10-17",
  "Id": "__default_policy_ID",
  "Statement": [
    {
      "Sid": "__default_statement_ID",
      "Effect": "Allow",
      "Principal": {
        "AWS": "*"
      },
      "Action": [
        "SNS:GetTopicAttributes",
        "SNS:SetTopicAttributes",
        "SNS:AddPermission",
        "SNS:RemovePermission",
        "SNS:DeleteTopic",
        "SNS:Subscribe",
        "SNS:ListSubscriptionsByTopic",
        "SNS:Publish"
      ],
      "Resource": "arn:aws:sns:ap-northeast-1:084251039480:aaa",
      "Condition": {
        "ArnLike": {
          "AWS:SourceArn": "arn:aws:s3:::venkyoiuyi"
        }
      }
    }
  ]
}
