Hello,
Re: Increase of Credit Limit
Account No. <account number>
I am writing in request an increase to the limit of my current credit line.
If you have a look at my past account history, you will find that I have always made my payments on time.
Thus, I am requesting you for raising my credit limit from [$ ??] to [$ ??].
I believe that your company has all the information about me for the evaluation of my account, but still if you require any additional information, please feel free to contact me anytime.
Regards,
Robert Anderson
