As long as a telephone number meets the requirements of a trademark, namely that consumers can rely upon it to distinguish the trademark owner's goods or services from those of competitors, then it can receive all the protections provided by trademark and dilution law. Typically, protection for phone numbers is sought for those numbers that are converted to a meaningful word, such as in the case of "Dial L-A-W-Y-E-R-S" in which a court enjoined another company's use of the same phrase, even though the defendant used that number outside of the region in which the original L-A-W-Y-E-R-S phone number was originally secured. See Murrin v. Midco Communications Inc., 726 F. Supp. 1195 (Minn. 1989).
