I work from home. I ship packages from here regularly with a company name on them, even though the house has no signage (for sale doesn't count) for a business. I also have recieved packages for my business without incident.

Over the year and half I have been working from home, I have closed one business (ok, it never really took off) and opened another. Currently I have two small businesses running out of my small 2800 sqft house. One is an Ebay trading assistant business, the other a computer related business. I still occasionally get mail for the first business which closed after 3 months- just industry magazines.

Yep.UPS/Fedex will recognize a business address just fine. Err, let me rephrase that. UPS will recoginize a street address. They don't care if you call yourself "UPS STINKS Inc.", as long as you have a legit street address. As for suite #s, you could probably get away with an A and B, or 1, 2,3, provided you have three different doors with numbers. I don't think they'd care if you had suite 450, 3rd floor on a 800 sqft one bedroom house, but why?

US Postal is the same way. The suite numbers may give them a problem. They HAVE to by law put mail in the correct box, so you'd need as many boxes as numbers. 12 numbers or letters, 12 boxes.

I've got a postal box at the UPS Store (formerly mailboxes etc) and I was told when I opened it NOT to use Apt# or Suite # as it could be confusing and cause problems (was on official USPS po box info sheet). I just use # and then the number and have never had a problem...

So, yes and no to your answer. Yes, a business name is fine. No a suite or floor number 'might' cause confusion if that suite or floor didn't exist....
