How to change your name with Southwest Gas
Married or divorced and updating your accounts? Here's how Southwest Gas takes a name change, from its own help page.
In person or by phone only. Southwest Gas is one of the few that won't change your name online. Call 877-860-6020 or visit, and bring your documents.
Southwest Gas's steps
Southwest Gas doesn't post online steps for a name change. Call customer service and ask what they need.
Have these ready
- A copy of your marriage certificate, divorce decree or court order (most companies ask for one).
- Your updated driver's license or ID, if you have it. Social Security comes first, then the DMV.
- Your account number, and the name the account is in now.
