The City of Austin 3-1-1 Call center can ONLY be accessed by phone numbers with the City limits. So residents living in North Austin M.U.D. #1 cannot call 3-1-1 because they are outside the City of Austin limits.
However, if you need information from Austin’s 3-1-1 Center you may call their full phone number and get through – this number is 512-974-2000.
