Phone Formatting

Sendiee stores and transmits all phone numbers in full international format without the + sign. Understanding this format is important for all endpoints that accept phone numbers.

International Format

All phone numbers follow the format {countryCode}{number} — no spaces, dashes, parentheses, or + sign.

The defaultCountryCode Field

If you pass a local phone number (without the country code), you can include the defaultCountryCode parameter and Sendiee will automatically prepend it.

Validation

Sendiee automatically sanitises phone numbers by removing spaces, + signs, dashes, and parentheses before validation. If the resulting number is still invalid, the API returns an INVALID_PHONE_NUMBER (400) error.
