I've just succeeded in parting with 7 Euro on line but not sure what I have! I thought I was going to get a yellow sticker al la French Crit but got a "Permit Registration" from Area Metropolitan de Barcelona. Seemingly that there is no sticker issued is in line with what is being said on this thread but the second page says Payment period 23/06/2023 to 08/07/2023. I thought I was getting a "life of vehicle" permit again al la French Crit but is what I have only valid for the 14 days? Not a lot of use as not likely to be around there until September! Did you get something similar or have I not applied for the correct permit do you think?I've registered my Hymer as a foreign vehicle so I can drive in the low emission zones in Barcelona. You don't get a sticker it's just an entry in their database so their ANPR cameras know I'm registered. Cost 7 euros.
