Hi
@Momwiz , I had a frustrating time the first time I used Correos, too. Another year when we needed it, it was much easier as I already had an account set up.
I would set up an account with them before you go. Right now, Correos is only doing winter transfers for the last 100 km on the CF and CP. If you are traveling before Easter, then you'll be limited to these routes for transfers. They may not have as many people staffed in winter to handle these service requests, but that is just a guess.
As someone else mentioned, they do have an English website and if you email them directly at
paqmochila@correos.com They should respond to you in English if you request it.
I called then each day to let them know where to pick up and deliver our bag in summer 2023 after we had to start shipping my husband's pack. They always had someone who spoke Englishto talk to me. You do need to make sure that where you plan to stay accepts bags. I had to change some plans as the places I selected did not accept bag transfers. Once bag shipping season begins, you can see the places that Correos delivers to on their website.
