# Do I need to purchase a number to publish SMS, Voice, and Webhook flows?

SMS: It depends on your country.

* For Germany, UK, and The Netherlands, you’ll have a shared number available with which you can create and publish an SMS flow.
* For all other [countries](https://docs.bird.com/connectivity-platform/country-restrictions-and-regulations), a UK Number will be assigned automatically unless not supported by local restrictions—as some [countries](https://docs.bird.com/connectivity-platform/country-restrictions-and-regulations) overwrite the sender ID—in which case you will indeed need to [buy a Dedicated Number.](https://docs.bird.com/connectivity-platform/virtual-numbers/buy-a-virtual-mobile-number-vmn) 

Voice: Yes, you need to [buy a Number](https://docs.bird.com/connectivity-platform/virtual-numbers/buy-a-virtual-mobile-number-vmn) to be able to publish your flow.

Webhook: No, you do not need to buy a number to be able to publish a Webhook flow. If there are SMS and Voice Steps inside your Webhook flow, the same requirements as above apply.
