To check a vendor’s legitimacy begin by:
Calling the vendor’s phone number listed – Do they answer as a business?
Check online with 3 different telephone sources to see if the phone number is listed for the vendor with the corresponding address provided.
Check online to see if a website for the vendor exists – Does it look professional?
Check the Better Business Bureau to see if the vendor exists on their site – Don’t forget to check the BBB rating.
While one can never be totally sure a vendor is not fraudulent take these steps to try and mitigate most issues.
