# Why can't I assign a call flow to a destination number in a different country?

|| For security and compliance reasons, free trial accounts cannot assign call flows with destination numbers in countries different from the country where the tracking number originates.

When you try to assign a call flow and see an error about country restrictions, this is expected behavior. Here's why it happens and what your options are.

# 1. Tracking numbers are region-specific

Tracking numbers can only be purchased or assigned in the same geographic region or country where your business (or your client's business) is legally registered.
This requirement exists to:

* Prevent misuse of numbers that could mislead callers
* Prevent disguising of call origin
* Prevent facilitation of fraudulent activities

| These restrictions may be enforced by local regulators, number providers, or platform-level rules within Nimbata.

# 2. Destination numbers are global

Destination number, the numbers that calls are forwarded to, can be from any country, subject to:

* Your account status
* Your plan limits
* Local telecom restrictions

This gives you the flexibility to route calls to international teams or remote call centers, while still maintaining compliance for the tracking number itself.

# 3. Cross-country routing on free trials

* On free trial accounts, cross-country routing between tracking numbers and destination numbers is restricted.
* Upgrading to a paid plan removes this restriction, subject to telecom regulations in the relevant countries.

🎉 In summary: tracking numbers are country-restricted by telecom compliance rules, while destination numbers can be international. If you're on a free trial and hitting this limit, upgrading your plan will give you full routing flexibility.
