You can register numbers as trademarks, and some numbers are still available.

Most of the numbers 1-99 are registered trademarks. The numbers 16, 26, 27, 28, 34, 36, 41, 42, 46, 49, 52, 54, 55, 58, 59, 60, 61, 62, 64, 65, 66, 68, 70, 71, 72, 73, 74, 78, 79, 81, 83, 85, 86, 89, 93, 94, 95, 96, and 97 are not (yet) registered trademarks. I expected that 11 would be registered to Spinal Tap, but it wasn’t. I expected 42 (the answer to everything) to be registered (in the spirit of “The Hitchhiker’s Guide to the Universe”), but it wasn’t. And I expected 66 to be registered (as in Route 66 or Phillips 66), but it wasn’t. If you are using a number to identify your goods or services, than you, too, may be able to register the number as a trademark.
