It is very important that you maintain only one Google Adwords account else you may get your account suspended as Google Adwords do not permit having more than one account per website or business.
If one will have more than one account than the other account will be suspended as you can see the message which appears in the Google Adwords account on having more than one account.
Why did we get this message?
We got this message as Google Adwords team got our new account made as we had a very old account with them which did not allow payment with cards and had only net banking enabled in it for payment. We were forced to start a new account as per Google Adwords team because worldwide Google Adwords was facing a problem as its net banking amount paid was not getting credited and was not being reflected in the account. They have escalated the issue with concerned branch and suspension will be soon revoked. We have now cancelled the earlier Adwords account and hope issue will be resolved soon.
The message is as appended below:
Your Google AdWords account has been suspended because your business maintains multiple AdWords accounts simultaneously serving ads for similar or related keywords and/or businesses. If you think this suspension was made in error, please contact us though this form or through Google Adwords toll free number in India and tell them the issue.
See screenshot below which you can not miss. However you can get the same rectified by approaching them through their customer care or by filling a form.
