- dylan604 4y agobecause they followed the rotary phone dial? i've seen number sequence examples that start with 1-9 followed by 0 as the 10th digit. bogus/placeholder credit card numbers commonly used 12345678901234 type of sequence. since 1 is technically the first digit of any phone number, placeholder number sequences often started at 1 and ended with 0 for 10 digit numbers. lots of people think of 1 as the first number (zero isn't really a number), so it's just a convenient place holder for that 10th digit written as a single digit.
