One hack around address limits is to put in a unit number. 1 Park Avenue or whatever in Manhattan will have multiple units in it. And if you live in one of these units you can add a letter, like "Unit 522B" which will just get delivered to your unit 522.

Some companies have databases that know the layouts in each address but many do not.

And when the grocery delivery person comes and sees the addresses don't match, your address gets blacklisted.

Never happened to me. If there are no letters after unit numbers, and the delivery person sees a delivery for unit 522B, they'll leave it at 522.
