For NA, you don't. But, you're not the only one - I'd submitted a bug report to Apple via the Apple Developer portal some time ago, and it's still open. To complicate it somewhat, bug-wise, the issue seems to be somewhat region-specific, e.g., I'm in Portland OR and all of my PDX Metro addresses work perfectly even with the "United States" tag included. But, heading just 8 miles north in Vancouver WA to my litigation attorney's office, the "United States" tag gets me about 1/2 mile away, and a visit to a client's office in Potlatch WA a few days ago gets me 2 miles farther up Highway 101 - backing out the "United States" tag gets me right to my attorney's office and much closer to the client's office (but still a few hundred yards off.

I noted that when there were errors at my attorney office (in a city) and client offices and mom's house (all in rural WA State), the errors were generally *exactly* in the same place, which is why I think it's a "blow" in GIS tagging - my attorney's office is shown 1/2 west in Bing (iOS/web), Apple (iOS), Mapquest (iOS/web), Teleatlas (Subars/Benz/TomTom GO/TomTom web) - but the Google Maps web (iOS and desktop) and Nokia Maps desktop show it correctly; the Nokia Maps web app is absofrickinlutely useless.
Short fix? I tap and hold on the contact's address and wait for "Copy" to pop up, then close the Contact's app, then open the Google Maps web app and paste the address into the search field - that gets me where I want to go most of the time.
Hey, we wanted free, right? Honestly, the $1600 head units in my Foz and GL450 are both crap too.
EDIT: Nokia Maps is hit and way-frickin-off. I'm connecting with a friend from Cork Ireland over the weekend, and she launched Nokia Maps to plan a trip. Our destination - 123 miles (way-frickin) off, and in the wrong state too. Nokia can póg mo thóin, we'll not be using them again!
