The issue is that census blocks almost always split down the middle of the street. ZIP codes rarely do because that would require two postal workers delivering mail to that street - one for each side of the street.

In the example, one mail carrier may deliver to 3 sides of the block via one ZIP code while another mail carrier delivers mail on the other street in a different ZIP code. When this happens, the Census Bureau will assign the entire block to a single ZCTA in this case, because the census block is the area that is precisely measured.

If you are getting very precise usually a matter of meters, not miles , census block boundaries near the edge of a ZIP code almost always split ZIP codes. Remember that ZIP codes were made to make mail delivery easier. They weren't made to correspond to existing boundaries such as cities, counties, or even states. If it is more efficient for a mail carrier to drive across a state line to deliver mail, the ZIP code "boundary" will cross the state lines.

These codes indicate a specific delivery route , meaning the actual path the mail truck would travel in a single drop-off. Usually this comprises ten to twenty homes or locations.

Because they are based on delivery routes instead of more permanent boundaries, the last 4 digits of a complete ZIP Code can change often. For another thing, they can help get you those bulk mailing discounts. That's right, your mail can show up faster if you label things right. Bet you're scrambling for those codes now, huh?
