This has always been bothering me; why is 45 Province Street high rise tower located on MLS as Beacon Hill?  Why does Beacon Hill need three zip codes?

Well, here’s you answer.

But, before I get into that, let’s first start off with how zip codes were formed.

The ZIP in zip codes stands for; Zone Improvement Program, and it was introduced by the United States Postal service in 1963. It was created to make postal deliveries more efficient by designating a code for every delivery area in the US.

The first digit of the ZIP code is used (as stated above) to group states into regions, for the example;

  • 0 = Connecticut (CT), Massachusetts (MA), Maine (ME), New Hampshire (NH)
  • 1 = Delaware (DE), New York (NY), Pennsylvania (PA)
  • 2 = District of Columbia (DC), Maryland (MD), North Carolina (NC), South Carolina (SC), Virginia (VA), West Virginia (WV)
  • 3 = Alabama (AL), Florida (FL), Georgia (GA), Mississippi (MS), Tenn

The two following digits are the code of a central post office facility in that region.

The last two digits designate small post offices or postal zones.

Sorry for the interruption. Just received an internet lead that I need to answer, so come back soon.  I’ll have more answers for you regarding zip codes.( I hope this is a sales lead.. )

Okay let’s continue, now that we know how zip codes were formed will view where the boundary lines are for each zip code.

So by viewing the map above, you can see how and why MLS sometimes places 45 Province Street a high rise condo building in the Beacon Hill neighborhood, as it falls into the Beacon Hill area zip code.

Back in the 1960’s perhaps this zip code zoning map made sense, but its now 2020. Which brings up another question

Can zip codes change? 

Yes! It’s not very likely that the USPS adds or subtracts a zip code, but they do shift zip code boundaries from time to time as delivery routes evolve.

How does this apply to the Boston real estate for sale market?

Before you list your Boston condo for sale, it doesn’t hurt to do a USPS Zip Code Search on your downtown Boston home to make sure you still have the correct zip code. It will also give you the +4 so you know you have the most accurate address possible!

Also remember if you’re looking for a Boston high rise condo on any Boston real estate website, don’t forget to check the Beacon Hill neighborhood, By doing so, you might find a Midtown high rise condo, overlooked by other Boston high rise condo buyers.
