Sportsbook userIDs

[Chcbleachers]

If you have a bookmaker account, your username will likely start with BKR.

Anyone know which site (likely affiliated with them) assigns usernames beginning with DOM?

Possibly one they have obtained over the years that may longer exist? I had one at the greek that moved there but already have Justbet so I never used, but it has different letters also.
