I'm not sure if License Certification can only be done at LTO, East Avenue. You can check with your nearest LTO satellite office to verify. You can get the License Certification at the licensing area (if my memory serves me right, Window 10). Prepare a photocopy of the expired license card and OR. One certification, one photocopy (I requested for 2 copies - 1 for National and 1 to bring along during the drive). Fill-up the form that they'll be giving you, and pay Php 100.00 per certificate at the License Fee Cashier window. I applied last Thursday, and will get it on Tuesday. All in all, the whole application process took me around 30 minutes. Hope this helps!
