If you take a look through your Android contacts, you’ll most likely see many variations in how the phone numbers are formatted. I’ve seen:

1 234 567 8900

(234) 567-8900


Although the Android platform supports multiple phone number configurations, staring at a hodge-podge of numbers can be dizzying when trying to sort through your multitude of contacts. If you’re a busy power user, it would behoove you to get those phone numbers into one standard format. But imagine reformatting hundreds (or even thousands) of contacts to the international standard:


The best application I’ve found to handle this task is Twitch! Contacts Formatter. Here are some features you’ll find with Twitch!:

  • Single click to standardize
  • International and national formats
  • Editable contact numbers
  • Select particular numbers to update
  • Skips invalid numbers
  • Auto-detect country
  • Update multiple contact sources

Using Twitch! gives you the power, with a single click, to standardize all valid phone numbers. How handy is that? Let’s get this installed and see how it’s done.


Installing Twitch! Contacts Formatter is simple. Just follow these steps:

  1. Open the Google Play Store
  2. Search for “twitch contacts” (no quotes)
  3. Tap the entry for Twitch! Contacts Formatter
  4. Tap Install
  5. Tap Accept

Once it’s installed, you should find the Twitch! launcher in the app drawer or on your home screen.


Using Twitch! Contacts Formatter is quite simple. Here are the steps:

  1. Open the application
  2. If your country isn’t correctly selected (indicated by a small flag at the top – Figure A), tap the flag and select the right country
  3. Tap either International or National format (from the map drop-down, next to the flag)
  4. Scroll through the list of numbers and de-select any number you don’t want converted
  5. When everything looks good, tap the Save button to convert

Twitch! Contacts Formatter detects the country code for the format from the phone’s SIM card. If, by chance, the detection is wrong (or there’s some reason you want/need to use a different format), just tap the flag icon and select the country you need to use as the basis for your number formatting.

You can also select between national and international formatting. The national format customizes phone numbers based on Google’s standard for that country. For example: U.S. phone numbers will show up as (123) 456-7890, while German numbers are displayed as 1234-567-8900.

In the listing, you’ll notice all invalid numbers are indicated with a “!” symbol. For those numbers, you’ll have to go back and manually convert them into one of the valid formats. Twitch! uses Google’s phone number formatting, and it will generally find phone numbers that are not in this format as invalid. For example: A U.S. phone number without an area code will be found as invalid. It doesn’t matter if the original format is:

  • (123) 456 7890
  • 1 (234) 567 8900
  • 123-456-7890

As long as it has the correct amount of digits, Twitch! Contacts Formatter should work just fine.

Once the save has completed, you can go back into the default Android contacts app and see that all valid phone numbers have been converted to the standard you’ve chosen (national or international). The one caveat to this is that you cannot undo the conversion (but there’s really no reason why you would want to).

If the phone numbers in your Android contacts are a formatting jumbled mess, install Twitch! Contacts Formatter to get those valid numbers following a recognized standard. This will make locating numbers faster and can even help you switch the default formatting on your phone.
