How to Find Out the Last Number That Called a Line

Updated April 17, 2017

So you missed what might have been an important telephone call to a landline phone with no redial button and no caller ID. You want that phone number. Even if the available phone is an antique with a rotary dial, your chances of getting the number are good. In the 1960s and 1970s, AT&T developed a set of codes to engage special telephone services. Those codes became a recognised standard still used today. "Identify Last Incoming Call" was one of those services.

Get a dial tone on the telephone line on which you want the number of the last incoming phone call.

Press "*69" (or dial "1169" on a rotary phone).

Listen for and record the number of the last incoming call. If you do not hear a voice providing that number (and it is not automatically redialed), go to Step 4.

Contact the landline service provider. At your location, a peruse option may not be available, or the "Identify Last Incoming Call" code may differ from "*69."


If you are likely to want last-incoming-number information three or more times a month, inquire about the monthly rate with your landline service provider. Rates start at 90p per month. Telephone companies charge the peruse fee at the time of delivery of an automated message.


In California, telephone number announcement is not allowed. Pressing "*69" dials the number immediately, without its being announced by a voice. In some states, landline service providers charge a fee just for disseminating the information that the last incoming call was private. An automated voice announcement may offer the option of having the number of the last incoming call automatically dialled. The phone company may charge a fee for this service. If the number is outside of the network of the landline provider, you will probably receive only that information.
