Modify number formats in Zaps

Formatter: Numbers

Formatter: Numbers

You can use Formatter’s Numbers transform to change number formats in your Zap. There are several different number transforms you can use.


If you have a United States phone number that needs to be formatted as an international number, you can use the Format Phone Number transform to add the “+1” country code before the number.

1. Add a Formatter step

  • In the Zap editor, click the Action step, or click the plus + icon to add a step to your Zap.
  • Select Format.
  • Click the Action Event dropdown menu and select Numbers.
  • Click Continue.
  • In the Set up action section, click the Transform dropdown menu and select the number transform you want to use.
  • In the Values section, click the Input field and enter the data that you want to transform. You can choose a field from a previous step or enter a value.
  • (Optional) If the Validate Phone Number? Field is set to Yes, the Zap will check if the phone number is valid for the country code selected (the United States is the default). Fake phone numbers (e.g. there is no 555 area code in the United States), phone numbers with too many or not enough numbers, or phone numbers with invalid characters will not be transformed.
  • Click Continue.

Some number transforms will have additional required or optional fields.

2. Test your number transform

  • Click Test & Review.
  • If the test was successful, you'll see the results of the number transform.

Once you've set up the Formatter Numbers transform step, you can use the results in further actions in your Zap.
