The ID for White Wings appears to be 15302762999. The result I found is for a Roblox item listing, which matches the kind of ID people usually mean when asking for a “gtag” or game code for wings.

Quick note

Google Tag IDs are a different thing entirely, and they look like G-XXXXXXXXXX or GT-XXXXXXXXX. So if you meant a Google tracking tag, that would be a different ID format than the wings code.
