Your Request For Accessing AWS Resources Has Been Validated

Hi Team, I have received the below email from aws.

[You recently requested an AWS Service that required additional validation. Your request has now been validated for AWS Asia Pacific (Mumbai) region(s). If you are still experiencing difficulty, please contact us at aws-verification@amazon.com <[[mailto:aws-verification@amazon.com]]>.]

This is 2 year old aws account. I was using only us-east-1 region. when I tried creating resources in another region, I got the email. I had not requested for any validation.

What is the reason I got this mail from aws?
