Wait, you have one of those personal P. O. boxes? I don't know about that part.
But in general, the answer is YES. If you bring stuff to the post office, they may ask questions. Its actually BETTER if you use an entirely different name for the return address, then you can simply explain that if the mail gets returned, you want it returned to your shipping department/shipper etc. However that brings me to a good point...
You CAN receive mail if its addressed to Tyler when your name is Taylor. Hell, they might just think its a typo. BUT you have to keep in mind, you're technically stealing Tylers mail which is a federal offense.
If you start to buy more expensive, big stuff with signature confirmation it can get VERY risky because they wont just drop it off at your door.
You CANNOT pick up your mail at the post office because they will ask you for your ID. They MAY be skeptical if its addressed to T Stevenson. Although, they will likely have no problem with that, it sounds like a good bet.
In general, you want to get the mail DELIVERED to you because the mail carrier doesn't give a crap who its addressed to. Even if you have to sign for it. But at the post office they WILL ID you.
You can schedule redeliveries online if you miss a package, that works. I actually went into the post office once to get a package with a different name on it, and they didn't give it to me, and I scheduled a redelivery online and got it.
You only have 3 chances though. So I say, it is risky to do.
Hope this helps.
One more thing, I am lucky enough to have 2 last names, but I have been putting the same name from my original account on a secondary address, with the street name and number on different lines, haven't gotten limited, no issues. Though I know most people wouldn't recommend this.
