Most of us have a TM fixed line phone at home. And there is a 4-digit number that when dialed, will reveal the phone number of that particular line.

Pick up any TM fixed line phone, dial 1313 and wait a couple of seconds, you will hear one or a series of beeps, followed by your phone number in Bahasa Malaysia. If your phone number is 03-7877 3803, you will hear tujuh lapan tujuh tujuh tiga lapan kosong tiga.
