Most memorizers have preset mnemonic images for each number -- usually 0-9 and 00-99. Competitors often have images for 000-999 to further reduce repeated images.

Example: 123-555-2222

123 is always encoded as "tomb" in my phonetic system. 555 is always lilacs. 22 is always an onion.

When an image repeats, I place a mirror at that spot.

So 123-555-2222 becomes: a tomb, lilacs, an onion, and an mirror. I store them in a certain order with a story to keep them in order.
