I got an email from HostGator asking me to provide additional verification information. Is this legit?

Yes, it’s legit. This only happens on a rare occasion, but sometimes HostGator (other hosting companies do this as well) will ask a new customer to provide additional information to verify their identity.

They do this to help prevent people from signing up using stolen personal information – however, don’t take it personally, as the selection process is often random and based on factors like your location.
