Id Field Type  is a base-62 encoded string. Each character can be one of 62 possible values: a lowercase letter (a-z) - 26 values an uppercase letter (A-Z) - 26 values a numeric digit (0-9) - 10 values Within a 15 character Id the breakdown is: (CASE SENSITIVE) First 3 characters - First 3 characters are the  key prefix  that identify the object type. In Case of Standard objects : Same Unique key prefix across all the orgs. (very useful in case you have hardcoded standard object id in apex, so now you won't need to change it when deployed in other org) In Case of Custom objects : Unique key prefix per Org, but have a different key prefix in each installed org. ( How to get object key prefix ) Remaining 12 characters - These is a 62^12 number. It is common to see the first character in this sequence set to a value other than 0 even though most of the following characters are zero. This appears to be some kind of offset and may have significance. Review...

Using Apex: You can use DescribeSObjectResult() method to get Custom and Standard Object prefix in apex class. For ex:  Lets say we have a custom object "Group_Task__c", and instead of hardcoding Object Id we want to make it dynamic. Schema.DescribeSObjectResult result = Group_Task__c.SObjectType.getDescribe(); PageReference pageRef = new PageReference('/' + result.getKeyPrefix()); pageRef.setRedirect(true); return pageRef; Using Workbench: Log into workbench-> go to Info > Standard & Custom Objects and pick an object from the pick list.
