The title may not make sense, but some examples:
-If your street address is 3465 Mongoose Lane, you may give it to the pizza place as “three four six five” or “thirty four sixty five” Mongoose Lane, but you’re almost certainly not going to say “three thousand four hundred sixty five Mongoose Lane”. The number is sequential and it’s not meaningless- your next door neighbors are probably going to live at 3463 and 3467 respectively (though they might live at 3455 and 3475 or something else, and the houses in front of you are probably 3464 or if there’s a park or church that takes up the entire block it may be 3400)- but chances are there aren’t really 3,400+ bulidings or lots on Mongoose Lane, and in fact the next street over could well be the 3500 block or might be the 3800 block due to some odd numbering (I’ve certainly seen odder).
Other examples: while your SSN isn’t randomly assigned, neither is it numerical (i.e. if it’s 987-65-4321 you’re not going to say “nine hundred eighty seven dash sixty five dash four thousand three hundred twenty one”. Same with phone numbers, credit-card numbers, bank routing numbers, confirmation number, etc.: the sequence may be orderly but it’s not meant to be read as a continual number, and while street addresses are usually sequential and routing numbers/credit card numbers are assigned due to some order (every part of a SSN/routing number/credit card number/etc. has some significance based on geography and or issuing agency and or customer number, etc.) there’s not really a base because it’s not a whole number.
So, hope I made it clear what I’m asking. Is there an actual term for these numbers?
