Choosing the right SMS sender is critical for successful message delivery. Different countries have unique requirements, so always check our Developer documentation for specific country regulations and requirements.

For North American countries (US or Canada), you must use a two-way SMS number. Bird recommends Toll-Free Numbers for the simplest, cheapest, and fastest approval process.

For countries outside North America, most messages use one-way Alphanumeric senders - a string of letters (up to 11 characters) representing your brand. In our case this is “Bird”.
