iPhone: How to Add a Signature to Text Messages

The Apple iPhone doesn’t have a way to create a signature for a text message the way you can for an email. There are a few apps on iTunes that claim to do this for you, but I don’t recommend any of them. They’re pretty cheesy, cost money and are a pain to use. You have to switch between the text and the app in order to insert the signature. Who wants to add those extra steps and time?

Thankfully, I figured out a way to add a signature of sorts to the end of all of my outgoing text messages (and iMessages) using a keyboard shortcut. It only takes a moment to set one of these up and you can easily insert it at the end of every text message.

NOTE – This method can be used for any and all phrases you find yourself typing regularly into a message such as a URL, phone number, address or anything else you use often. Just follow the steps below to create a new keyboard shortcut and then use it while you type!

To create a keyboard shortcut:

  1. From the Home screen, open “Settings“.
  2. Choose “General“.
  3. Scroll down to find the “Keyboard” field and tap on it.
  4. Towards the bottom of this next screen, you will see a section called “Shortcuts” and an option titled “Add a New Shortcut“.
  5. Tap on the “Add a New Shortcut” field and the box will open for you to create your shortcut, which will turn into a “text signature” for you.
  6. In the “Phrase” field, type whatever it is you want to use as a shortcut or signature within text messages. Keep in mind that texts are supposed to be on the short side, so don’t create something insanely long here.
  7. In the “Shortcut” field, type the 2-3 letter shortcut you will use to bring this signature up within a text. When you are finished, tap the blue Save button in the upper-right corner of the screen.

Using the Shortcut as your Signature

In my example photo above, I chose to have the short phrase “Blessed Be” show up at the end of my text messages. When I am finishing up a text message, I just type bb at the end and my shortcut will pop up. I then simply tap the space bar and iOS places the shortcut/signature within the message for me.

Be creative – if you want to end your texts with something like:

You would type this into the Phrase field in the screen to create the shortcut. For the shortcut trigger, you could then use something such as “siggie” to trigger it.

You can choose to use whatever you’d like as your shortcut “signature” – short is usually always better when sending an SMS. Likewise, the trigger shortcut should be something around 2-3 letters for the most part and easy to remember. You’re trying to save yourself time, not add to your troubles.

    This is great! I only wanted to add a signature, but I can use this for all kinds of messages. Thank you.

    Thank you so much for this. Brilliant! just transferred back from Android so it was irritating without the signature! plus EVERYONE didn’t recognise me (apparently messages transmit on iCloud).

    Highly recommend this!!!!

    Thank you so much! This is a great idea b/c I don’t need a signature on every text message.
