I got a memorable phone number a while ago. Websites like numberbarn.com make it relatively easy. A key realization I had is that repeating numbers aren’t the thing to look for, because they’re what everybody is depleting and marking up, and actually aren’t a very good proxy for what you really care about, which is memorability and maybe aesthetics. For example, 34567 is better than 37771, and also more likely to be available and cheap. Repeating digits and their associated markup are also about typability, but that probably barely matters to you if people are almost always calling from their address book.
