Eircode (our version of the postcode in the UK). Stick that in the satnav (or my address) and he'd find me. I'd even left my mobile number on my porch door for the driver to ring. We could then have arranged for me to collect the parcel from him (I live a mile from where I work), or he could have called in to my workplace on his way back to civilisation. Or, if he didn't need a signature, I could have told him where a key for the porch was hidden outside. But they seem to have a rotten reputation.
