eli5 Why do house numbers skip digits?

1.61K views

My brother lives at 35 Parson Lane, yet the next-door neighbor is at number 25. My last house was number 10, the next-door neighbor was at number 12. Why all the number skipping? Why not just go in numerical order starting with 1, then 2, etc.

As others have mentioned, you have odd numbers on one side of the road and even numbers on the other so that it’s easy for others (delivery people, visitors…) to tell which side of the road you’re on when they lok for your house.

Distance plays a role as well. I used to live on a rural dirt road with only about a dozen houses, yet my house number was >400 while my next-door neighbor was about 80 numbers lower.

That said, different places have different rules. My parents who live in a different town in that same county have a house number below 50 despite having more houses on their road. Their town still follows the even/odd system, but the progression is a bit different.
