Format Definitions for OA IDs and WCAIDs

Ryan Morlok

Are there published format standards for the format of [WCA][1] IDs and [OA][2] IDs? Informally I've understood WCA IDs to be Novus-style guids (33 characters with the first being 'i') and OA IDs to be integers, but I was wondering if there is documentation that can confirm this will always be true.

I received confirmation that OA IDS are always numbers (the column in OA DBs has an NUMBER(19) to store the data). WCA IDs are stored in string column, and I haven't been able to get 100% confirmation that their format is guaranteed, but below are examples that seem to indicate that their format is consistent.


Examples of WCA Company GUIDs: ('I' followed by 32 Hex characters: 0-9,A-F)
