How To: Add Extensions or Extra Digits to iPhone Telephone Numbers

You're listening to the latest, greatest TiPb Phone Different Podcast. Mike and Dieter are on fire. And then... out of nowhere... they cross the line. They say something so outrageous you just have to respond, to retort, to -- quite frankly -- set them straight. You grab your iPhone, hit the Favorite for Phone Different Feedback and...

You get the soothing tones of the answer-bot, asking just what extension you're trying to reach... What extension?! D'oh! Rantus Interuptus!

Next time you want to give our humble hosts (or anyone else) a quick call, save yourself some frustration and add the extension right into your iPhone contact info!

We'll show you how, after the jump!

Okay, here's how you can add extensions -- or any form of extra digits -- to a telephone number on your iPhone.

First, access your Contacts (either via the Phone App, or the dedicated Contact App in 2.x). Pick the Contact you want, and tap Edit in the top right corner. Next, pick the phone number you want to add the extension to, and then tap the +*# button on the bottom left of the Dial Pad.

As the button label implied, you can add the plus, star, or pound symbols. Tap Pause to add a comma (,) -- or short, silent wait period. Add the numbers for the extension, then tap Save to apply the changes.

And we're done! Have more Contacts you'd like to extend? Simply rinse and repeat as often as needed. Then get ready for the next Podcast, and let Dieter and Mike know how you really feel -- fast!

If someone could come up with a way to keep the telephone number form instead of the long line of numbers that would be great.

Hammer says:

After putting these extension numbers in my iPhone dials the extensions EXTREMELY slow...any idea why and can I change that?

Paul says:

I have the same problem, did you find a solution?

Naseer Malik says:

I added pause to my contact so I could have extensions but it seems to be invisible as when the main number is dialed the iPhone screen displays either key pad or the other screen carrying options of mute etc. Pls advise how to make extension dialing option visible.

Jeff L. says:

Naseer, you're probably either picking the default contact number to call which doesn't have an extension I guess, or you need to Hide Sources, then simply hit Keypd if all you want to do is dial when you're within a call..

Errol Hoberman says:

Any one know how to print my contacts, or hoe to edit contacts on my Desk Top, iTunes? other?

Andrew K says:

I want the extra digits to "play" only when I tell them to, after a "wait." The "+" sign seems to be the wait, but what makes the extra digits "play" after that?

Ferdinand says:

Thanks for this helpful tip. Any tricks for getting this phone number + extension combination to work when embedded in a Calendar appointment or e-mail message?

Again, blackberry wins. The dialing options are simply much better thn Apple has been able to give us in the lady three years. Extentions, waits, pauses, full control over dialing. And it works on Verizons network. Sigh.

Ljone says:

y obviuos design of a 30 year old who never had to hit and extension number for stores, doctors, pharmacies, etc. A real Iphone glitch that is ridiculous.

Patricia Hinestrosa says:

That works for extensions, but what about international numbers?
