If you live on 6th St in Emery what syntax do you use?

Our mail service is in Florida. At suggestion of our mail service we use Apt. instead of PMB. You could also use "Unit" with no "#" sign.

I have a Private Mail Box (PMB) at a parcel store and they have told me that as long as my box number is on the address - so that they don't have to look it up - they don't care what designator is used.

It could say BLDG, UNIT, APT, STE, SUITE, #, PMB - they don't care.

If I can't enter PMB, I'll try #, and then APT.
