On the 1 - Brand Registration tab, once your customer profile and A2P messaging profile are both submitted (not draft or rejected) you see "You may register your Brand to the Campaign Registry" and a button. The first click opens a Brand Registration window explaining that a one-time $5 fee must be paid to comply with the A2P 10DLC regulations; click Pay One Time Fee and confirm — the card on file for your Sprwt account is charged. After payment, click the register button again to submit the brand. You will see an error if the brand is already registered, if the profile or messaging profile status is draft/rejected ("Please check your Customer Profile Status" / "...A2P Messaging Profile Status"), or if the fee has not been paid ("You need to pay the brand registration one time fee first"). Each brand submission consumes the paid fee.
