After you have downloaded Snapchat on your device, open the app and select the signup option, open Snapchat and select the signup option. Enter your name, birthday, email address, username, and password. Since this is a business account and not a personal account, make sure to make your username the name of your brand or company. Next, enter your phone number and wait for a verification code to be sent to your phone number. Once you receive the verification number, enter it.
At this point, Snapchat will ask you if you want to upload your contacts. It is recommended to only do this if you have a lot of business contacts or if you need more Snapchat followers. If most of your contacts are personal, then you will probably want to skip this. And just like that, you now have a business Snapchat account and you have completed the first step to Snapchat marketing.
