27700

27700 is a five-digit number that is primarily known as a postal code in France. In the French postal system, the first two digits of a five-digit code indicate the department; 27 corresponds to Eure, a department in the Normandy region. The code 27700 is used for the town of Les Andelys and several nearby communes along the Seine valley, facilitating mail routing and delivery.

Les Andelys is situated on the right bank of the Seine, upstream from Rouen. The area is noted for the Château Gaillard, a late 12th-century fortress built by Richard the Lionheart that overlooks the river and the town. The surrounding countryside features cliffs and river scenery that attract visitors.

As a number, 27700 factors as 277 × 100, or 2^2 × 5^2 × 277. It is divisible by 100 and is thus composite, ending in two zeros. It lies between 27699 and 27701. Outside its postal designation, 27700 may appear in various numeric contexts as a product or model code, but it does not have a single widely recognized meaning beyond its role as a postal code in Eure.
