You won't need to request an increase as your ZebitLine can grow with you. We re-evaluate the performance of accounts on a 3-6 month basis and may increase your ZebitLine. Evaluation for increases generally start 6 months after your first order is placed. Strong purchase and on-time payment history are important in our evaluation of your ZebitLine and late payments may prevent you from getting an increase. So once you make your first purchase, please remember to sign-up for auto-pay so you do not miss a payment.
