Did you know there is a logic to the street numbers in Paris? There is, and it’s really quite simple and has helped me many times in pre-cell phone days or when I am on a bike and my phone is in my pocket.

The rule is very simple and distinguishes streets running (roughly) perpendicular to the river and streets running (again, roughly) parallel to the river.

For the perpendicular streets, numbering starts on the end closest to the river. Uneven numbers are on the left, even numbers on the right. So if you’re looking for a number higher than the one in front of you, go away from the river.

For the parallel streets, numbering starts upriver. The south side of the street will have the uneven numbers, the north side the even numbers. So if you’re looking for a number higher than the one in front of you, go downriver.

Easy-peasy, right?
