E04057 — ContactPhoneInvalid
This does not look like a phone number. Send the international form, a leading plus sign, then the country code and number, for example +31612345678.
- HTTP status: 422
- Type: validation_error
- Name: ContactPhoneInvalid
What to do
Send the number in international E.164 form. Bird checks only the E.164 shape, never whether a number is currently assigned or known to numbering-plan metadata.
