## Teaser 2985: What’s my (land) line?

**From The Sunday Times, 8th December 2019** [link]

My telephone has the usual keypad:

My [11-digit] telephone number starts with 01 and ends in 0. All digits from 2 to 9 are used exactly once in between, and each pair of adjacent digits in the phone number appear in a different row and column of the keypad array.

The 4th and 5th digits are consecutive as are the 9th and 10th and the 8th digit is higher than the 9th.

What is my number?
