a!formatPhoneNumber() Function

Function

a!formatPhoneNumber( phoneNumber, countryCode, outputFormat )

Returns a formatted phone number based on the outputFormat parameter. The countryCode parameter, or any country code provided in the phone number, will verify that the phone number is valid. If the phone number does not match any provided country code, the phone number will be returned as invalid and unformatted.

Usage considerations

Using the countryCode parameter

The countryCode parameter can include one or more country codes. If you provide multiple country codes, the phone number will be formatted as the first matching country code. See a list of country codes.

If the phone number does not match any of the provided country codes, an error will appear.

If no countryCode is provided, but the phone number contains an international code (+[country code]), then the function will use the international code to determine if the provided phone number is valid.

For example, let's say you provide the phone number +34 913 30 28 00 without providing a countryCode parameter. Since +34 is the international code for Spain, the function will return a valid phone number in the specified outputFormat.

Using the outputFormat parameter

Specifies whether the phone number is formatted as a national, international, E164, or RFC3966 number.

For example, when testing the United States phone number 703-555-5555, the different outputs would appear as follows:

)

Returns tel:+44-20-3514-2838

Using a list of country codes

The countryCode parameter can accept an array of country codes. You may want to add a list of country codes if your application is used across multiple countries so you can format different phone numbers accordingly.

In the example below, there are two country codes: Mexico and United States. Since the phone number is a United States phone number, the function will skip the first country code (Mexico) and format the output as a United States phone number.

a!formatPhoneNumber(
  phoneNumber: "703 555 5555",
  countryCode: {"MX", "US"},
  outputFormat: "NATIONAL",
)

Returns (703) 555-5555

Using this function without a country code

The countryCode parameter is optional if an international code (+<international code here>) is provided as part of the phone number.

For example, the example below does not need the countryCode parameter since the international code (+52) is part of the provided phone number.

a!formatPhoneNumber(
  phoneNumber: "+52 55 5487 3100",
  outputFormat: "NATIONAL",
)

Returns 55 5487 3100

However, if you tried to use the following example, the function would return an invalid phone number because there is no international code in the provided phone number, and no countryCode parameter.

a!formatPhoneNumber(
  phoneNumber: "55 5487 3100",

Returns Invalid phone number: 52 55 5487 3100

Using this function in an interface

The following example uses the a!isPhoneNumber() and a!formatPhoneNumber() functions to validate and format a user-provided phone number, which could be a phone number in the United States, Great Britain, or Germany.
