*69. Should work in most North American Places with POTS service (Plain Old Telephone Service)
Just look in your caller history.
*69 will give you the number of the person that last called - usually.
It is the code # used when you want to find out the identity of the last person(s)who called you. You must make sure you use it BEFORE your next caller though as you will lose the ability to find out who it was and you will only get the number info on that next caller.
*69
Look at the Caller ID display.
1471 then press 3
The easiest way is to call someone who has Caller ID (for example, call your own cellphone from the land line). There are also special numbers you can dial to have the telephone switch read back to you the phone number, but those numbers vary from place to place and phone company to phone company.
If you call 1471 AFTER you have been called, it gives you the number who has just called you. This will not work for some private telephones and will not work for Business e.g. BT. NOTE YOU CAN ONLY GET THE LAST NUMBER THAT HAS CALLED YOU. Hope this works
In the US and Canada, *69 (or 1169 on a rotary phone) will redial the last number that called you, provided that you received valid Caller ID information and the caller didn't block it. If the Caller ID information was blocked, or if it got lost somewhere along the line, you can't call it back. The phone company may have additional information about the caller, using a different system called ANI that tracks the billing number, but you need to file a formal complaint and jump through some other procedural hoops to get that information.
*67 than dial the number. *69 to find out who called you last.
In North America, *69 will redial the number of the last person who called you. However, it does not work if the person blocked their caller ID, or if it's a telemarketer who sent a fake caller ID, or if for any other reason you didn't receive valid caller ID information.
Depending on the phone company, *67 usually will tell what the last number dialed is. Unfortunately, most people making calls like this will block the number. Also, use caller ID, and finally, get the phone company or the police involved.
