Night bus routes are often related to the day numerical equivalent, normally running the same route but with an extension at either end of the service. This is normally to provide a night service to destinations served by tube or train during the day.
However, there are a few N-prefixed route numbers that have no relation to their daytime equivalents: the N5, N20 and N97 all operate in a different part of London to their respective day routes, and the N550 and N551 (which provide night service on parts of the DLR network) have no corresponding daytime routes.
There are also 24-hour routes, which run day and night but usually with a lower frequency during the night hours. The vast majority run the same route at all times.
