How to create a login to pay your bill

Accessing your GRTI account online is a useful tool. You will need a bill handy when first registering your account. To begin, you will first need to register by following these steps:

  1. Click Continue.
  2. Click Register Now under New User to register
  3. Once on the registration form, you will be asked to enter your 10 digit account number as it appears on your bill statement, followed by your security code. Your security code is 217 followed by the last four digits of your telephone number. Example: 2173333
  1. You will now be asked to create a user name and password which will be used for future logins.
  2. You can now view your bill, make payments, manage payment options and more by using the user ID and password you created.
  3. Be sure to write down your information for future reference.
