I had a parcel coming from the USA. I was not in and had a card from Parcelforce saying to go to my local Post Office to collect it. I had to take either my driver's licence or, a household bill with my name and address on it to retrieve my parcel. It was all straightforward enough, I just had a form to sign, that was it. Having said this, on a previous occasion, it was the sorting office I'd to collect from.
