Amazon lockers - locker number?

[Bletchleyite]

I buy quite a lot of stuff from Amazon (this thread isn't for a debate on whether I should or not) and always collect at a locker if offered for that item.

One thing I've noticed is that when you do the collection the display shows e.g. "Open locker #3" to press to open it. But that number appears to have no basis, other than that I've never seen a number higher than 3. If you have stuff in more than one it gives you a button for the other locker, but the numbers again seem arbitrary, e.g. sometimes you'll get 1 and 3, sometimes 2 and 3 etc. But they clearly aren't the actual number of the individual compartment as they're not consistent and seem never to exceed 3.

Anyone know how it's derived or if it's just random?

I believe it’s derived from the item number when you’re collecting multiple items in one go, as they can and do deposit multiple items in the same locker, even on subsequent deliveries. So if it says “1 and 3”, it means locker 1 contains items 1+2, and locker 3 contains item 3 (and above).

The lockers themselves aren’t numbered in a user-visible way. Some older systems work that way, but it’s crazy as the user collecting the item doesn’t care.

Cheers. I've wondered for ages and not managed to work it out!
