Will id field contain number only or can contain characters??

LS_760hw7

When I am listing issues using the endpoint /rest/api/3/search?jql=(project=10000). In json response I am getting id field as string. So I need to know whether id will contain numbers only or can contain characters??.

    "issues": [

        {

            "expand": "operations,versionedRepresentations,editmeta,changelog,renderedFields",

            "id": "10010",

         }

      ]
