How well do you know your texting slang?
458 is a variant of ILU - both of which mean "I love you." The numbers 4, 5, and 8 correspond to the letters I, L, and U on a telephone keypad, producing this heartfelt numeric abbreviation.
You're most likely to receive 458 from old-school chatters and texters, who used to text from a cell phone keypad. In the past, sending 458 in place of ILU saved these olds a bit of time. Now, they keep using 458 because they think it's kewl.
