A: No. PO Box 12987 is a mail receptacle, not a physical office. You cannot visit it. You must ship via postal service.
If you have recently initiated a Samsung warranty claim, a trade-in, or a repair request, you may have encountered a puzzling piece of text in your shipping instructions: followed by a request to include your IMEI number . At first glance, this combination of a postal box in Ireland and a unique device identifier seems technical and obscure.
PO Box 12987, Dublin, Ireland
You might have entered the IMEI of a different phone (e.g., a secondary device) during the online form, then sent a different phone.
