How to get RecordTypeId without SOQL | Get RecordTypeId by Describe Call

Some time in code we need to get recordTypeId . For that generally we used SOQL like below :-

Id contRecordTypeId = [Select id from RecordType where sObjectType = 'Contact' and developerName ='NameOfRecordType' ].id ; 

You can try below Describe to get record Type Id without SOQL

Id contRecordTypeId = Schema.SObjectType.Contact.getRecordTypeInfosByName().get('NameOfRecordType').getRecordTypeId();

 Please check below post for more detail

If you want to get the Prefix of any object . Please try below code.

String keyPrefix = Account.sObjectType.getDescribe().getKeyPrefix();
System.debug('PREFIX--' + keyPrefix );

If you want to get the Object Name from RecordId then please try below code.

public class SchemaGlobalDescribeToGetObjectName
{
    public static String findObjectNameFromRecordIdPrefix(String recordIdOrPrefix)
 {
  String objectName = '';
        try
  {
            String IdPrefix = String.valueOf(recordIdOrPrefix).substring(0,3); 
            Map<String, Schema.SObjectType> gd =  Schema.getGlobalDescribe(); 
            for(Schema.SObjectType stype : gd.values())
   {
                Schema.DescribeSObjectResult r = stype.getDescribe();
                String prefix = r.getKeyPrefix();
                if(prefix!=null && prefix.equals(IdPrefix))
    {
                    objectName = r.getName();
                    System.debug('Object Name! ' + objectName);
                    break;
                }
            }
        }catch(Exception e){
            System.debug(e);
        }
        return objectName;
    }
}

If you want to Get the Object prefix by Workbench then please try below step :-

The easiest way to find out which key prefix maps to which object is by using a tool like the workbench . After you log into workbench, go to and pick an object from the pick list.

Step 1 :- Login in to Workbench
