As an Alberta resident, that is definitely not how our postal system operates, unfortunately.
Ash is correct, they alternate between letters and numbers.
Also regarding lighthouses we’re pretty landlocked ?
I appreciate you exploring all possibilities though. What about an American zip code? In New York or otherwise? I’m unsure how they work.
I tried looking at Aberdeen (can get as far as AB10), but the closest I can find a lighthouse is in AB11 (and still can’t figure out the last few numbers).
Also tried looking into grid reference maps, but doesn’t look like AB is a letter pair used, and there’re either too many or two few numbers.
UK postcodes are an area code (one or two letters) and a number (one or two digits), then a number and 2 letters. Couple of examples; CA12 7QO or B2 6ND (both made up, with CA for Cardiff and B for Birmingham). With only 2 letters, this cannot be a UK postcode.
Okay, I’m back and just as perplexed as you guys. I’m working on a longer post, but the gist is that I think I finally found the A.G. shipment. I mean, I think I know where it is. But now I’m waiting for someone there to confirm it’s there, and that I can have it. Update very soon.
