Summary
Standard and Custom Objects in Salesforce have three character prefixes which form the first part of the Record ID.
For example, a User record with ID 00561000000Mjya has the prefix 005, which is the prefix for the User Object.
For a list of Standard Field Record ID prefixes, please see Standard Field Record ID Prefix Decoder.
In some scenarios, you may want to find out the name of the Object associated with the prefix using Apex code.
Solution
If the Object id is ‘00561000000Mjya’, run the following code in ‘Execute Anonymous Apex’
Id sampleid = '00561000000Mjya'; System.debug('object is '+ sampleid.getsobjecttype());
You can use an alternate approach. Create the following Class SchemaGlobalDescribe.
Please note, if the org has many objects you may run into Apex CPU limit error. In that case, please adjust the following code to exclude managed packages or filter accordingly.
public class SchemaGlobalDescribe{
public static String findObjectNameFromRecordIdPrefix(String recordIdOrPrefix){
String objectName = '';
try{
//Get prefix from record ID
//This assumes that you have passed at least 3 characters
String myIdPrefix = String.valueOf(recordIdOrPrefix).substring(0,3);
//Get schema information
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();
//Loop through all the sObject types returned by Schema
for(Schema.SObjectType stype : gd.values()){
//if (!sObj.contains('__')) to exclude managed package objects
Schema.DescribeSObjectResult r = stype.getDescribe();
String prefix = r.getKeyPrefix();
System.debug('Prefix is ' + prefix);
//Check if the prefix matches with requested prefix
if(prefix!=null && prefix.equals(myIdPrefix)){
objectName = r.getName();
System.debug('Object Name! ' + objectName);
break;
}
}
}catch(Exception e){
System.debug(e);
}
return objectName;
}
}
