There are letter codes attached to the numbers 2 through 9, the same as originally used to designate named telephone exchanges in the early days of telephones.
2 - ABC
3 - DEF
4 - GHI
5 - JKL
6 - MNO
7 - PQRS
8 - TUV
9 - WXYZ
The letters have become used to identify otherwise innocuous numbers, e.g. a phone number such as 555-5879 might be used by a trial lawyer because the number can be easily remembered as 555-JURY.
