Kind of similar here. I have an almost photographic memory, but only really for numbers.

When I newly moved here, I went out shopping for furniture. At the cash register, the lady asked me what my postal code was for delivery. At that point, I had never properly read my full address, but it was on the contract I had signed. So, I went into the back of my brain, found a screenshot of that and could read out the code. Then I obviously double-checked, but yeah, I got all 5 digits right.
