numbers grouped in twos are great for mnemonic memorization. you'll easily come up with an association for many two digit numbers.

ex. 415-222-9670 becomes: sub universal (one less than the answer to life, the universe and everything) deck (52 cards) swift (she's feeling 22) resolution (old dpi on wandows) top speed (California speed limit)

now isn't "sub universal deck swift resolution top speed" easier than googling twitter hq? ;] granted, the associations have to make sense to you. for me, 96 was a toss up between nashville (code name of windows 96) and the resolution i had to train myself to remember after moving from the mac's 72.
