Salesforce ID Uniqueness


Are SFDC IDs unique across all of SFDC or can you only assume an ID is unique within a particular org? If an sObject with a particular ID is deleted, could that ID come back again in the same org or another one for a new sObject?

Possible Suggestion/Solution #1

For your initial question:


Short Answer

Yes for Production Orgs (Sandbox's can have the same object Id as the Production Org they were cloned from)

For your second question:

I would expect this to be the case however I wouldn't rely on it as with any auto increment field in a database there could come a day when those Id's are reallocated for use.
